Jesus and Jewish History Explained — Studying Religious Philosophy, Abraham to the Messianic Expectation

Introduction — Why This Lecture Matters

This lecture stands at a specific and important juncture in the history of Western thought. We have traced Greek philosophy from its pre-Socratic origins through Plato, Aristotle, and the Hellenistic schools; and we have seen how Neoplatonism served as the philosophical bridge toward medieval thought. Now we enter the Judeo-Christian tradition — the second pillar of Western intellectual history. Together, Greco-Roman and Judeo-Christian thought constitute the foundation on which virtually all subsequent Western philosophy, ethics, politics, and culture are built.

This lecture has three purposes. First, it introduces the methodological principles necessary for studying religious philosophy without distortion. Second, it maps the key conceptual differences between major religious frameworks — differences that must be understood before any specific tradition can be fairly studied. Third, it tells the story of Jewish history from Abraham to the birth of Jesus: a story without which neither the New Testament nor the philosophical tradition that followed it can be properly understood.

Part One — How to Study Religious Philosophy

1. The Context Principle

The most fundamental requirement for studying religious philosophy is the recognition that every tradition operates within a specific metaphysical and cultural context — a framework that gives meaning to every term it uses. The same word can mean something entirely different depending on which framework it is used within. A philosopher who does not attend to this context will misread every tradition they study.

This is not a problem unique to religion. In Greek philosophy, as we have seen, the word ‘god’ means something different in Plato (the Demiurge — a craftsman working with pre-existing matter), in Aristotle (the Unmoved Mover — an impersonal self-contemplating intelligence), in Stoicism (the Logos — a rational principle pervading matter), and in Epicureanism (blessed beings who take no interest in human affairs). Each usage is coherent within its own system; each is incompatible with the others. The same logic applies to every major religious tradition.

Judaism, Christianity, and Islam each describe their God differently. Each has its own understanding of the soul, of salvation, of the relationship between God and the world, of time, and of the proper mode of worship. A student who approaches any of these with the implicit assumption that the categories of their own familiar tradition are universal will understand none of them correctly.

2. Ex Nihilo vs Brahman Expansion — The Root of All Differences

The single most important conceptual distinction for understanding the difference between Western Abrahamic and Dharmic religious frameworks is the question of how the world came into existence. Everything else — every difference in practice, vocabulary, and ethical framework — flows from this foundational metaphysical question.

The moortipooja example: Christianity forbids idol worship; Dharmic traditions practice it. Many people observe this difference without understanding why it exists. The answer is entirely metaphysical. In the Christian framework, the world was created from nothing — it is not God and contains nothing of God’s essence. Worshipping a created image would therefore be worshipping something that has no divine substance — a category error at best, an act of idolatry at worst. In the Dharmic framework, the world evolved from Brahman. Every object in the world, including an image or statue, is made of substance that is Brahman’s own expansion. Focusing worship through that image is therefore focusing on the divine that is genuinely present within it. Both positions are internally consistent. Neither is arbitrary.

3. Holy vs Divine — The Vocabulary Gap

Religious language is precise in ways that casual usage does not reveal. Two words that appear to be rough synonyms — ‘holy’ and ‘divine’ — carry fundamentally different meanings in the Western Abrahamic framework, and conflating them produces systematic misreading.

This distinction matters concretely. In Christianity, the correct phrase is ‘Holy Bible’ — not ‘Divine Bible.’ The Bible is sacred, spiritually pure, set apart for God, and authoritative — but it does not contain God’s substance. The phrase ‘Divine Grace’ is correct because grace is God’s direct property, an expression of God’s nature itself. A reader unfamiliar with this distinction will misread Christian texts consistently.

In the Dharmic framework, both ‘holy’ and ‘divine’ apply to the Gita — it is spiritually pure (holy) and it contains the divine essence (divine), because in the Dharmic account everything exists within Brahman and therefore contains Brahman’s nature. A reader who understands only the Christian framework will find this claim puzzling; a reader who understands the Dharmic metaphysics will find it precise.

4. Soul vs Atman — Not the Same Concept

Perhaps the most frequently confused pair of concepts across traditions is soul and atman. They are often used interchangeably in casual discussion, but they are not the same concept and cannot be substituted for one another without significant distortion.

• Soul (Abrahamic concept): Each individual person has a unique soul — distinct from every other soul. This soul does not reincarnate. It is the specific person God created; it will be judged after death and will be either reunited with God or separated from him for eternity. There is no cycle of birth, death, and rebirth.
• Atman (Dharmic concept): The atman is the same in all beings — not individual. It does not belong to ‘me’ specifically; it is the universal self, which the individual personality (jeev) mistakenly identifies with. The atman undergoes rebirth through successive lifetimes. Liberation (moksha) comes from realising that the individual self is not separate from the universal atman — and through it, from Brahman.

These are not different names for the same thing. They are conceptually distinct, grounded in different metaphysical frameworks, and lead to entirely different ethical, spiritual, and philosophical implications. Treating them as equivalent produces confusion in both directions.

5. The Abrahamic Traditions — Internal Differences

A further layer of complexity is that even within the Abrahamic family — traditions that share a common ancestor in Abraham and a common commitment to monotheism — the differences are substantial and philosophically significant. Judaism, Christianity, and Islam are not the same tradition under different names. They share a family tree; they do not share a doctrine.

6. Why This Matters for Philosophy

A student might reasonably ask why a philosophy course needs to cover this religious and comparative material. The answer is direct: because Western philosophy from the fifth century onward cannot be understood without it.

When Augustine writes about the soul, he is using a concept whose meaning depends on the entire Abrahamic framework. When Kierkegaard writes about faith, he is engaging with concepts — covenant, commandment, the paradox of obedience — that come from Jewish and Christian scripture. When Nietzsche attacks morality, the morality he attacks is specifically the morality shaped by the Judeo-Christian tradition. When John Locke grounds political rights in natural law, he is drawing on a tradition of moral thinking rooted in the idea that humans are created in God’s image.

Moreover, Western philosophy texts routinely reference Biblical events, figures, and concepts — the fall of man, the second coming, original sin, exodus, the covenant — and assume readers already know what these mean. For a student formed in a different cultural tradition, this assumption is false. Making these references explicit is not optional background reading; it is essential equipment for understanding the texts themselves.

Part Two — Jewish History: From Abraham to the Messianic Expectation

Jesus was a Jew. His disciples were Jews. His earliest followers were Jews. The text that Christianity calls the Old Testament is the Jewish scripture. The theological categories that the New Testament uses — covenant, law, prophet, messiah, sin, redemption — are Jewish categories. Christianity cannot be understood except from within Jewish history. That history spans roughly four thousand years; what follows is the philosophical core of it.

1. Yahweh — The Name and Its Meaning

The God of the Jewish people has a specific name: Yahweh. This name was not invented by human beings and applied to God — according to the Jewish tradition, God revealed this name directly to Moses when Moses asked who he was. ‘I am that I am,’ God said — ‘My name is Yahweh.’

The name Yahweh is built on the Hebrew verb ‘to be.’ Its most basic meaning is ‘I am’ — pure existence, being itself. Various interpretations have been offered across centuries of Jewish and Christian scholarship: Yahweh as self-existent being; Yahweh as the ground of all existence; Yahweh as the one who simply is, without beginning or cause. What unites these interpretations is the identification of God with existence itself — not a being among other beings, but Being as such.

Jews do not pronounce this name. The third of the Ten Commandments prohibits misusing God’s name, and out of deep reverence for this commandment, Jewish tradition has for centuries avoided pronouncing Yahweh at all. In reading scripture aloud, the word Adonai (Lord) is substituted. This is not ignorance of the name — it is a form of honour, an acknowledgment that some things are too sacred for casual use.

2. Monotheism in a Polytheistic World

One of the most significant facts about the emergence of Judaism is how unusual its core commitment was in the ancient world. Virtually every ancient religion was polytheistic — believing in multiple gods, each with a specific domain, a specific personality, and specific limitations. The Greeks had Zeus, Hera, Poseidon, Artemis, Apollo and dozens more. The Egyptians had Ra, Osiris, Isis, and a complex divine hierarchy. The Romans absorbed and adapted the Greek pantheon. The Mesopotamians — in the very region where Judaism emerged — worshipped Marduk, Enlil, Ishtar, and many others.

Monotheism — the belief in one God, and one only — was not a natural or obvious position. It had to be worked out slowly, over generations, against the surrounding cultural current. Even within the Jewish community itself, the history of the Hebrew Bible shows a long struggle between strict monotheism and the persistent pull toward the polytheistic practices of neighbouring peoples.

The Jewish God differs from the gods of other traditions in several philosophically important ways:

• All-powerful (omnipotent): Unlike Greek gods — who had limited domains and could be resisted or tricked — and unlike Plato’s Demiurge — who worked with pre-existing matter and eternal Forms — Yahweh has no limitations. He created the world from nothing and answers to nothing outside himself.
• Personal: Unlike Aristotle’s Unmoved Mover or the Stoic Logos — which are impersonal rational principles with no interest in individual human affairs — Yahweh is a personal God. He speaks to people, hears prayers, responds, becomes angry, shows mercy, and enters into covenants with individuals and communities.
• Creator ex nihilo: He required no pre-existing material to create the world. This distinguishes him sharply from the Platonic Demiurge and makes the question of the world’s relationship to God fundamentally different from anything in Greek philosophy.

3. The Patriarchs — Abraham to Moses

4. Abraham — The Beginning of the Story

The Jewish story properly begins with a man called Abram, living in Ur — a city in what is now southern Iraq — around 1800 BC with his wife and father. Abram was not a great king or a priest. He was an ordinary person who believed in one God in a world that believed in many. God spoke to him with a remarkable promise and a remarkable demand: leave your home, go to a land I will show you, and I will make of your family a great nation that will bless the world.

Abram trusted this promise and went — at the age of seventy-five, with no children and no clear destination except ‘Canaan,’ the region that is today’s Israel and Palestine. When he arrived, God renewed the promise and gave him a new name: Abraham. His wife was renamed Sarah.

Sarah, troubled by her childlessness, suggested that Abraham have a child with her servant Hagar. Abraham agreed, and a son was born: Ishmael. God blessed Ishmael. But God had more to say. When Abraham was approximately one hundred years old, God appeared to him again with a specific promise: Sarah herself would bear a son. And she did. They named him Isaac.

The two lines of Abraham: This moment — the birth of both Ishmael and Isaac — has world-historical consequences that are still unfolding. Jews trace their lineage through Isaac. Muslims trace their lineage through Ishmael. Both are Abraham’s children; both traditions are therefore Abrahamic. The connection between Jews and Muslims is not merely symbolic — according to both traditions, they are literally the same family. At Sarah’s insistence, and at God’s direction, Hagar and Ishmael were eventually sent away. Ishmael settled in the Arabian Peninsula, where his descendants — according to tradition — became the ancestors of the Arab peoples. The twelve sons of Ishmael became princes of twelve Arab tribes. This is described from the Jewish perspective; the Islamic tradition tells the story somewhat differently but shares its main outline.

5. The Test of Abraham — Akedah

The most theologically significant event in Abraham’s life is what Jewish tradition calls the Akedah — the binding of Isaac. God came to Abraham with a command that seems incomprehensible: take your son Isaac, whom you love, to a mountain in the region of what is now Jerusalem, and sacrifice him as a burnt offering.

Abraham obeyed. He and Isaac made the journey. On the mountain, Abraham bound Isaac and raised his knife. At that moment, an angel called out from heaven: stop. Do not harm the boy. This was a test. Now God knows that your faith is complete — that you hold nothing back, not even your most beloved child. Abraham looked up and saw a ram caught in a thicket; he sacrificed the ram instead of his son. The blessing was renewed: your descendants will be as numerous as the stars of the sky and the grains of sand on the seashore.

This story is at the centre of Jewish faith and has generated vast amounts of interpretation across three millennia. It raises urgent questions: what kind of faith demands this? What kind of God asks for a child’s life? What does it mean to obey absolutely when obedience conflicts with everything we know of love and ethics?

Kierkegaard — Fear and Trembling: The Danish philosopher Søren Kierkegaard took the story of Abraham and Isaac as the central case study for his analysis of faith in his short but demanding book Fear and Trembling. Kierkegaard asks the question directly: how can we possibly call Abraham a hero — even a spiritual hero — when he was prepared to murder his own son? Reason says Abraham was about to commit something monstrous. Faith says Abraham was the most obedient and trusting of all human beings. Kierkegaard argues that faith is precisely this: a paradox that cannot be rationalised, a leap beyond what reason can authorise. Faith and reason can genuinely conflict — and in the story of the Akedah, they conflict absolutely. Kierkegaard does not resolve this conflict; he insists that it cannot be resolved. This makes Abraham not a comfortable moral example but a deeply disturbing one — and for Kierkegaard, that is precisely the point. A full discussion of Fear and Trembling will come in the Kierkegaard lecture.

6. Jacob — The Wrestler Who Became Israel

Isaac married Rebecca and had twin sons: Esau, the elder and physically powerful, and Jacob, the younger and intellectually gifted. The brothers were in conflict from the beginning. When their father Isaac, old and nearly blind, prepared to give his blessing to Esau, Rebecca helped Jacob deceive him — dressing Jacob in goatskins to make him feel like his hairier brother, and presenting him to his father for the blessing. Isaac gave the blessing to Jacob. When Esau discovered what had happened, he was furious, and Jacob fled.

Jacob went to Haran, where he married Leah and Rachel. With Rachel he had a son named Joseph. Years later, Jacob decided to return to Canaan and reconcile with his brother Esau. The night before the reunion, something extraordinary happened.

The wrestling at the ford: A man came in the night and wrestled with Jacob until dawn. The struggle lasted the whole night; neither could overpower the other. As the sun began to rise, the man said: let me go. Jacob refused: ‘I will not release you unless you bless me.’ Jacob was wounded in the struggle but would not stop. The man — who was, the text makes clear, a divine messenger, an angel of God — said to him: ‘You shall no longer be called Jacob. Your name is now Israel, because you have wrestled with God and with human beings, and you have prevailed.’ Israel means ‘the one who wrestles with God,’ or ‘the one who struggles with God.’

The name Israel becomes the name of the entire people: the children of Israel, the Israelites. A nation defined by its wrestling — by its engagement with difficult questions, its refusal to accept easy answers, its willingness to struggle with the divine even when the struggle is painful.

Jordan Peterson — We Who Wrestle With God: The psychologist and cultural commentator Jordan Peterson took the title of his book, We Who Wrestle With God, directly from this story. Peterson argues that Jacob’s night-long struggle at the ford is not a quaint mythological episode but a vivid picture of the universal human condition. Every person, in every era, must wrestle with the deepest questions of meaning: what is life for? What is worth suffering for? What is the right thing to do when there is no clear answer? What does genuine faith look like in the face of genuine suffering? Jacob’s struggle is an inner struggle — not just a physical combat but a confrontation with the most difficult dimensions of existence. The blessing comes not despite the struggle but through it. You must engage; you cannot bypass the wrestling.

7. Joseph — The Dreamer in Egypt

Jacob had twelve sons, but his favourite was Joseph, born to his beloved Rachel. The other brothers grew resentful of the favouritism and eventually sold Joseph to slave traders. Joseph was taken to Egypt, where — after years of hardship including false accusation and imprisonment — his gift for interpreting dreams brought him to the attention of Pharaoh.

Pharaoh had dreamed of seven fat cows devoured by seven thin cows, and seven full ears of grain swallowed by seven withered ones. No one at court could explain the dream. Joseph interpreted it: seven years of extraordinary plenty would be followed by seven years of devastating famine. His advice was practical and brilliant — use the abundant years to stockpile food, so that Egypt would survive the famine and have surplus to sell to surrounding nations. Pharaoh, recognising both the interpretation and the wisdom, appointed Joseph as Egypt’s chief administrator.

The famine came exactly as Joseph had predicted. People from across the region came to Egypt to buy food — including, eventually, Joseph’s own brothers. After a complex and emotionally charged series of encounters, Joseph revealed himself to his family and forgave them. Pharaoh, grateful for Joseph’s service, invited the entire family of Jacob to settle in Egypt. The Israelites — the children of Israel — came to Egypt and settled there.

8. Moses, the Exodus, and the Torah

Generations passed. The Israelites grew numerous in Egypt, but so did the suspicion with which the Egyptians regarded them. A new Pharaoh came to power who knew nothing of Joseph and feared the Israelites’ numbers. He enslaved them. And then, seeking to prevent their growth further, he ordered that every Hebrew newborn boy be killed at birth.

Into this world Moses was born. His mother placed him in a woven basket and set it on the Nile river to save his life. The basket was found by a woman who turned out to be the Pharaoh’s daughter, who took the child in and raised him in the royal household. Moses grew up in Pharaoh’s palace — an Israelite by blood, an Egyptian by upbringing.

One day Moses saw an Egyptian overseer beating an Israelite slave with brutal force. He intervened and killed the Egyptian. Fearing the consequences, he fled from Egypt. He settled in the wilderness, married, and lived as a shepherd. Then God appeared to him — in a bush that burned without being consumed — and issued the call that would define Moses’s life: ‘Go back. Free my people from slavery. Bring them to the land I promised Abraham.’

Moses returned. He confronted Pharaoh. Pharaoh refused. God sent ten plagues upon Egypt — the last and most devastating being the death of every firstborn Egyptian child. After this final plague, a grief-stricken Pharaoh agreed to release the Israelites. Moses led hundreds of thousands of people out of Egypt in what the tradition calls the Exodus — one of the most formative events in human religious history.

As they fled, Pharaoh changed his mind and sent his army after them. They reached a great body of water. According to the narrative, the waters parted; the Israelites crossed on dry ground; when the Egyptian army followed, the waters returned and the army was destroyed. The Exodus — the liberation from slavery — was complete.

On the way to Canaan, the community stopped at Mount Sinai. There, God spoke to Moses and gave him the Ten Commandments: the foundational moral and religious code of the Jewish people. No other gods; no idols; honour the sabbath; do not murder; do not steal; do not bear false witness; do not covet. These commandments, together with the extensive body of law that surrounds them, constitute the Torah — the term for both the Five Books of Moses and the wider body of Jewish religious law that guides every aspect of Jewish life.

The Israelites wandered in the wilderness for forty years. Moses died before entering Canaan — God showed him the promised land from the summit of a mountain, but he did not cross over. Joshua led the people into Canaan. A new chapter of Jewish history began.

9. From Canaan to Roman Rule — The Long Struggle

The Israelites settled in Canaan. The period of David and Solomon — roughly the tenth century BC — was the high point of their political independence: a unified kingdom, a stable state, relative peace. But this stability did not last. The Assyrian Empire conquered the northern kingdom of Israel in the eighth century BC. The Babylonian Empire took Jerusalem and exiled much of the population in the sixth century BC. Alexander the Great’s conquests brought the region under Greek Hellenistic rule. And finally, in the first century BC, the Roman Empire absorbed the region into its vast imperial structure.

The Jews experienced the Roman occupation as one more chapter in a long story of foreign domination — a story in which their God had promised them land, freedom, and greatness, and history seemed to have delivered the opposite. This produced a profound and persistent question that runs through the entire prophetic tradition: if God chose us, why do we suffer this way?

10. The Messianic Expectation

From within this history of suffering and foreign rule came one of the most powerful ideas in the history of religion: the expectation of a Messiah — in Hebrew, Mashiach, meaning ‘the anointed one.’ The belief that God would send a specific individual to break the cycle of defeat, drive out the foreign powers, and restore the glorious and peaceful era associated with David’s reign. This Messiah would be God’s appointed agent of liberation and restoration.

It is essential to understand that this messianic expectation was, at its origin, primarily political and national. The expected Messiah was not, in the original Jewish understanding, a divine being — he was a human leader, anointed by God for a national mission. The transformation of this concept into a primarily spiritual one was one of the most significant and contested developments in the history of Judaism and early Christianity.

Part Three — Jesus, Crucifixion, and the Reform of Judaism

1. Jesus — Dates and Historical Context

Jesus was born approximately in 4 BC — though the exact date is uncertain and scholarly estimates range from around 7 BC to the early first century AD. The uncertainty is a genuine historical one, not merely a matter of convention; the calendar we use today was developed centuries later and the synchronisation with earlier records is imprecise. For philosophy, as the lecturer notes, the precise date matters less than the ideas. Augustus Caesar was the Roman Emperor at the time of Jesus’s birth.

Jesus died by crucifixion approximately in 29 to 30 AD, during the reign of Emperor Tiberius. His active ministry — the period of his public teaching, healing, and the gathering of followers — lasted approximately three years. In that time he attracted devoted followers and intense opposition, both from Roman authorities and from conservative Jewish religious leaders. The crucifixion was not an accident of history but the planned consequence of that opposition.

2. Crucifixion — The Context of Jesus’s Death

Crucifixion was the most severe punishment available in the Roman legal system — reserved for slaves, foreigners, and those convicted of the most serious crimes against the state. It was designed not merely to kill but to humiliate, to deter, and to make the death as public and as drawn-out as possible. Understanding what crucifixion actually was is necessary for understanding the theological weight that early Christians placed on Jesus’s death.

The process followed four stages:

• Flogging: The condemned person was first beaten with a flagrum — a whip with multiple leather straps embedded with metal balls and shards of bone. This beating alone could bring a person close to death.
• Carrying the beam: The condemned then carried the horizontal wooden beam (not the whole cross, as is often depicted) to the execution site. This site was deliberately chosen to be maximally public — a city gate, a market, or a prominent hillside — so that as many people as possible would witness the punishment.
• Binding or nailing: At the execution site, the person was either tied or nailed to the beam, which was then raised on an upright post. Both methods were used; nailing was particularly severe.
• Left to die: The person was then left — sometimes for hours, sometimes for days — to die of asphyxiation, blood loss, shock, or exposure. Death was slow and public by design.

This was the death Jesus underwent. The event is referred to in these notes, as in scholarly convention, as the crucifixion rather than simply ‘death’ — because the manner of the death is theologically and historically inseparable from its meaning. The crucifixion and what Christians believe followed it — the resurrection — constitute the absolute centre of Christian theology. Everything else in Christianity is commentary on or response to these two events.

Historical instances of crucifixion: Crucifixion was used extensively by Rome throughout this period. Spartacus, the gladiator who led a massive slave revolt against Rome, was defeated around 71 BC; Rome crucified approximately six thousand of his soldiers along the Appian Way as a deterrent. Saint Peter, one of Jesus’s closest disciples, was executed by crucifixion under Emperor Nero. According to tradition, Peter requested to be crucified upside-down — considering himself unworthy to die in the same position as Jesus.

3. Jesus as Jewish Reformer

One of the most important and sometimes overlooked facts about Jesus is that he did not come to found a new religion. He was a Jew, trained in Jewish scripture, teaching in Jewish synagogues, and addressing Jewish audiences about their own tradition. His earliest followers were entirely Jewish. The movement that eventually became Christianity was, in its first generation, a Jewish reform movement — an attempt to recover the original spirit of the covenant with God from beneath the accumulation of centuries of legal elaboration.

To understand what Jesus was responding to, one must understand what had happened to Jewish religion in the centuries before his birth.

4. The Evolution of the Prophetic Message

The Hebrew Bible contains a remarkable and philosophically important internal development: the concept of God’s character and what God actually wants from human beings shifts and deepens across the prophetic tradition. This is not a simple linear progression, and scholars interpret it in various ways — as genuine theological development, as deeper understanding of an unchanging God, or as a gradual correction of earlier misunderstandings. For our purposes, the important thing is the content of the shift.

The trajectory is clear. The movement is from external to internal, from thundering power to gentle whisper, from ritual performance to the condition of the heart, from law as the letter to law as the spirit. This movement did not resolve cleanly, however. Jewish religious life in Jesus’s era was shaped by a complex negotiation between these impulses, and the legal framework of the Torah had, over centuries, become extraordinarily detailed and comprehensive.

5. Deuteronomy and the Problem of Rigid Legalism

The Book of Deuteronomy — whose title means ‘the Second Law’ — represents an important attempt to resolve the tension between ritual observance and inward devotion. It sought to harmonise faithful love of God with careful obedience to the commandments: the commandments are not a burden separate from love but the expression of love; love is not a vague sentiment but one that shapes every dimension of life.

The problem is what happens when harmonisation becomes codification. The attempt to specify exactly what faithful love looks like in every possible situation produced, over generations, an enormously detailed legal system. Every aspect of daily life — what to eat, when to work, how to pray, what to wear, how to wash — was governed by specific rules. This was, in its original intention, an expression of the conviction that all of life belongs to God. But it created a new risk: that meticulous attention to the rules could become a substitute for the inward life the rules were meant to express.

Jesus identified this risk as the central problem of the religious practice of his time. Deuteronomy sought to harmonise ritual and love; what had resulted, in his view, was a system in which the rules had swallowed the spirit. People were following the letter of the law with great care while missing — or actively evading — its meaning. The prophets had said this four centuries earlier; Jesus was saying it again, with the urgency of someone who believed the situation had become critical.

6. Jesus’s Reform Mission

Understanding Jesus as a Jewish reformer rather than the founder of a new religion is essential for understanding the content of his teaching. He was not introducing an entirely alien framework — he was appealing to the deepest layer of his own tradition against what he saw as its distortion. ‘I have come not to abolish the law but to fulfil it,’ he said — meaning that the law’s true fulfilment is the spirit it was always meant to express.

The prophets — Amos, Hosea, Micah — had already articulated this spirit: God wants justice, love, and kindness; God is not impressed by ritual performed with a corrupt heart. Jesus’s teaching extends and intensifies this prophetic tradition. In the Sermon on the Mount, he moves systematically beyond the letter of the commandments to the inward disposition they were meant to form: not merely ‘do not murder’ but ‘do not harbour hatred’; not merely ‘do not commit adultery’ but ‘do not harbour lust’; not merely ‘love your neighbour’ but ‘love your enemy.’

Whether this reform succeeded in its original intention — the transformation of Judaism from within — is a question Jewish and Christian scholars continue to debate. What is historically clear is that the movement Jesus inspired separated from Judaism within a few generations, took on its own institutional form, and eventually became, under the influence of the Roman Emperor Constantine’s conversion, the official religion of the Roman Empire in 380 AD. The teaching of a Jewish reformer became the foundation of a new civilisation.

Conclusion

This lecture has covered ground that is necessary for everything that follows in the history of Western philosophy. The methodological principle — study every tradition on its own terms, within its own framework — is not merely good manners; it is a requirement of intellectual honesty. A philosophy that cannot engage respectfully and rigorously with frameworks different from its own is not philosophy — it is provincialism.

The Abrahamic traditions, in all their internal diversity, have shaped Western thought as profoundly as Greek philosophy. The concepts of a personal God, of covenant, of sin and redemption, of linear time moving toward a final judgment, of every human being as uniquely created in God’s image — these are not peripheral ideas. They are the metaphysical and ethical air that Western philosophy has breathed for two thousand years. A philosopher who does not understand them cannot understand the tradition they are studying.

Jewish history — from the promise to Abraham through the slavery in Egypt, the Exodus, the giving of the Torah, the prophets’ increasingly inward interpretation of God’s demands, the centuries of foreign domination, and the messianic expectation that defined the world into which Jesus was born — is not separate from philosophy. It is the living context from which one of the most philosophically productive religious traditions in human history emerged. Understanding it is not optional equipment; it is essential preparation.

Frequently Asked Questions

Why must religious philosophy be studied with such care about context?

Because every religious tradition uses words that appear familiar — God, soul, worship, salvation, creation — but assigns them meanings shaped by a specific metaphysical framework. When those meanings differ fundamentally across traditions, using a word from one tradition to describe another produces distortion rather than understanding. The most vivid example in this lecture is the word ‘God’: in Plato it refers to a craftsman working with pre-existing matter; in Aristotle it is an impersonal self-contemplating thought; in Stoicism it is a rational principle pervading matter; in Judaism it is a personal, all-powerful creator who speaks to human beings and enters into covenants with them; in Christianity it is a triune being whose second person became human; in Islam it is an absolute unity that admits no partners or internal divisions. These are not variations on a single concept — they are genuinely different frameworks. Studying any of them requires learning that framework first, setting aside whatever sense of ‘God’ one might bring from elsewhere, and reading the tradition through its own logic.

What is the philosophical significance of the difference between ex nihilo creation and Brahman expansion?

The metaphysical difference between ex nihilo creation and Brahman expansion is not merely a theological technicality — it generates entirely different answers to the most basic philosophical questions about reality, knowledge, ethics, and the self. If the world was created from nothing by a God who stands completely apart from it, then the world contains no divine substance, the self is a creature rather than a manifestation of the divine, study of the external world is not study of God, and prayer must be directed to a transcendent being who is not present in things. If the world evolved from Brahman as Brahman’s own expansion, then every thing in the world is a form of the divine, studying anything — including the self — is studying Brahman, meditation is a valid path to ultimate knowledge, and worship can be directed through any form since every form contains divine essence. Every specific difference between Western Abrahamic and Dharmic religious cultures — from worship practices to views on reincarnation to the nature of liberation — traces back to this foundational metaphysical difference.

What is the Akedah and why does Kierkegaard find it philosophically significant?

The Akedah is the Hebrew name for the story in Genesis in which God commands Abraham to sacrifice his son Isaac — and Abraham prepares to obey, only for an angel to stop him at the last moment. In Jewish tradition it is the supreme example of faith tested and proven. For Kierkegaard, in Fear and Trembling, it is philosophically significant precisely because it cannot be made comfortable. He asks: by any ordinary ethical standard, what Abraham was about to do was monstrous — the murder of his own child. No ethical reasoning can justify it. Abraham’s willingness to proceed does not rest on any argument; it rests entirely on his relationship with God and his absolute trust in God’s word. This means that faith, as Kierkegaard understands it, is not a lower form of reason or a supplement to it — it is a different and in some respects conflicting mode of commitment. Faith can demand what reason forbids. This creates what Kierkegaard calls the ‘teleological suspension of the ethical’ — a suspension of ordinary moral rules in response to a direct divine command. Whether this is admirable, terrifying, or both is not a question Kierkegaard resolves. He presents Abraham as genuinely incomprehensible to ordinary ethical thinking — which is, for Kierkegaard, precisely what makes him a figure of faith rather than of ethics.

Why is the story of Jacob wrestling with the angel philosophically important?

The story of Jacob wrestling through the night and being renamed Israel — ‘one who wrestles with God’ — carries several layers of philosophical significance. At the most obvious level, it gives the Jewish people their name, and defines them as a people defined by their engagement rather than their passive reception. But at a deeper level, the story makes an extraordinarily bold claim: that wrestling with God, refusing to let go, demanding to be blessed rather than simply submitting — this is the proper response to the divine. Jacob does not win the fight; he is wounded. But his persistence is rewarded. The blessing comes through struggle, not around it. Jordan Peterson, who built his book We Who Wrestle With God on this story, argues that this is not a peculiarly Jewish insight but a universal description of the human condition: the deepest goods in human life — meaning, identity, faith, virtue — are not received passively. They emerge from engagement with the most difficult questions, the hardest circumstances, and the greatest resistances. Avoiding the struggle does not lead to the blessing; it leads to the forfeiture of it.

What did Jesus mean by reforming Judaism, and why did it become a new religion? Jesus’s intention, as far as it can be reconstructed from the historical and textual record, was to recover the spirit of the Jewish law that he believed had been buried under centuries of increasingly rigid legal elaboration. The prophetic tradition — Amos, Hosea, Micah — had already made this argument four centuries earlier: God is more interested in justice, love, and the condition of the human heart than in meticulous ritual performance with a corrupt interior. Jesus extended this argument with an urgency and directness that was characteristic of him. He was not rejecting the Torah — he said explicitly that he came to fulfil the law, not abolish it — but insisting that the law’s true fulfilment is inward rather than outward. His conflict with the religious authorities of his day was precisely this: they focused on the letter; he insisted on the spirit. Why this reform became a separate religion rather than a renewed Judaism is a complex historical question involving the content of Jesus’s claims about himself, the fact of his crucifixion and the belief in his resurrection, the destruction of Jerusalem in 70 AD, and the gradual separation of the Jesus movement from Jewish institutional life. It was not an inevitable outcome — it was the result of specific historical pressures over the first century of the Common Era.
