HEBREWS, ISRAELITES AND JUDEAN
Before we begin this section let’s take a moment to define the terms Hebrew, Israelite, and Judean (or Jew). These terms are related but distinct stages in the history of the ancient Jewish people. Hebrew is the earliest designation, traditionally referring to Abraham and his descendants, and later to the people who spoke the Hebrew language. Israelites were the descendants of Jacob, whose name was changed to Israel, and they formed the twelve tribes of ancient Israel. After the kingdom of Israel split, the southern kingdom was called Judah, and its people became known as Judeans.
Table 1: Identities and Historical Contexts
| Term | Brief explanation | Historical context |
|---|---|---|
| Hebrew | An early term used in biblical texts for people associated with the ancestors of the Israelites, particularly figures such as Abraham and his descendants. | Most useful when discussing the biblical patriarchal traditions and early origins of the people who would later be identified as Israelites. Its precise historical/ethnic meaning is debated. |
| Israelite | A member of the people identified with Israel. In biblical tradition, the Israelites descended from Jacob, also called Israel, and his twelve sons. Historically, “Israel” is independently attested by the late 13th century BCE. | Especially appropriate for the Iron Age and the peoples associated with ancient Israel, including the kingdoms of Israel and Judah. |
| Judean / Judahite | A person associated with Judah, the southern kingdom centered on Jerusalem. After the northern Kingdom of Israel fell to Assyria in 722/721 BCE, Judah remained an important center of Israelite political and religious life. | Particularly useful for inhabitants of the Kingdom of Judah and, later, the province of Yehud/Judea. The term eventually contributed to the development of the designation Jew. |
Over time, the term Jew (derived from Judean) became the common name for the people of Judaism, especially after the Babylonian Exile, and remains the primary term used today. Before continuing, let’s look at these terms a little closer through the writing of Christine Elizabeth Hayes below.
| Christine Elizabeth Hayes, Introduction to the Bible: Defining Hebrew, Israelite, and Judean/Jew “Hebrew is the name employed in some biblical sources to designate the most ancient ancestors of the Israelite people. It is primarily an ethnic and linguistic term denoting persons who spoke Hebrew, a Canaanite dialect. The Hebrews are thought to have established themselves in the land of Canaan (roughly modern-day Israel) by about 1200 B.C.E. The terms Israel and Israelite refer to a member of the twelve Hebrew tribes of the Israelite ethnos who inhabited Canaan, eventually forming themselves into a united kingdom around 1000 B.C.E. The kingdom of Israel later split into a northern kingdom, Israel, and a southern kingdom, Judah. Although any member of the twelve tribes was a member of the Israelite ethnos, inhabitants of the northern kingdom were Israelites also by virtue of being from the kingdom of Israel, while inhabitants of the southern kingdom were (additionally) known as Judeans by virtue of being from the kingdom of Judah. However, with the destruction of the northern kingdom in 722, the only Israelites remaining were the Judeans, and thus the terms Israelite and Judean become somewhat interchangeable (except in contexts that refer clearly to the former inhabitants of the destroyed kingdom of Israel). Falling under Persian rule at the end of the sixth century, the area around Jerusalem was named Yehud and the term Yehudi (often translated “Jew” but more properly “Ju-dean”) referred to an inhabitant of Yehud/Judea. It would be some centuries before the term Yehudi was understood to designate an adherent of the tradition of Judaism (a Jew), rather than an inhabitant of the province of Yehud/Judea (a Judean).” |
THE TANAKH
Judaism, encompassing the beliefs, identity, and practices of the Jewish people, is a monotheistic religion centered on the worship of one G-d. Worship is expressed through words, prayers, sermons, and the reading of scripture. This is conducted in synagogues under the guidance of rabbis (teachers). At the heart of Judaism are four key beliefs that have profoundly shaped its practices, values, and worldview.
Table 2: The Four Key Beliefs of Judaism
| 1. Monotheism | The foundational belief of Judaism is that YHWH (often pronounced Yahweh) is the one and only G-d, the creator of all existence. |
| 2. Obedience to G-d’s Law | Humanity is called to obey G-d’s law, which is expressed in both the written Torah and the oral traditions. These laws guide Jewish life and practice. |
| 3. The Covenants | The Covenants: Judaism emphasizes a series of covenants made between G-d and the Jewish people, designating them as the chosen lineage. Among the most significant covenants are: – With Abraham: The promise of a nation. – With Moses: The giving of the Law. – With David: The establishment of a kingdom. |
| 4. The King-Messiah | Judaism holds the belief in a coming King-Messiah who will deliver the Jewish people from foreign domination and restore peace and justice. |
Judaism evolved from two key sources. These were the history of the ancient Hebrews and the writings of the Tanakh (known in Greek as the Septuagint). The Tanakh is not a single book but an anthology of sacred texts, “written and compiled over a period of a thousand years, from approximately 1100 to 100 BCE.” It consists of twenty-four books and takes its name from the Hebrew acronym for its three sections, These are the Torah (Law), Nevi’im (Prophets), and Ketuvim (Writings). Of these, the Torah, the first five books (also known as the Pentateuch) is considered the most important, as it lays the foundation for Jewish law, ethics, and belief.
Table 3: The Torah
| Book of the Torah (Pentateuch) | Hebrew Name | Meaning | Main Content |
|---|---|---|---|
| Genesis | Bereshit | “In the Beginning” | Creation of the world, Adam and Eve, Noah and the Flood, Tower of Babel, and the stories of the Patriarchs and Matriarchs (Abraham, Sarah, Isaac, Rebekah, Jacob, Rachel, Leah, and Joseph). |
| Exodus | Shemot | “Names” | The Israelites’ slavery in Egypt, Moses’ call, the Ten Plagues, the Exodus, the crossing of the Red Sea, the giving of the Ten Commandments at Mount Sinai, and the covenant with God. |
| Leviticus | Vayikra | “And He Called” | Laws concerning worship, sacrifices, the priesthood (Levites), ritual purity, festivals, and the Holiness Code, emphasizing holy living. |
| Numbers | Bemidbar | “In the Wilderness” | The census of the Israelites, their forty years of wandering in the wilderness, challenges to Moses’ leadership, and preparation to enter the Promised Land. |
| Deuteronomy | Devarim | “Words” | Moses’ farewell speeches reviewing Israel’s history and laws, renewal of the covenant, and preparation for entering the Promised Land before Moses’ death. |
It consists of five books (Genesis, Exodus, Leviticus, Numbers, and Deuteronomy) which describe the origins of the world, God’s covenant with Israel, the Exodus from Egypt, the giving of the Law, and the Israelites’ journey to the edge of the Promised Land.
The early texts of the Tanakh have undergone centuries of theological interpretation and analysis. These texts are largely etiological, meaning they aim to explain how or why certain aspects of the world or human experience came to be, rather than being strictly prescriptive or normative.

They recount G-d’s creation of the world and humanity, detail the early history of the Hebrew people, establish the covenant between G-d and the Jewish people, and offer foundational guidelines for ethical and ritual behavior.
THE HISTORICAL NARRATIVE OF THE TANAKH
The Tanakh begins with the creation of the world by G-d, who brings the cosmos into existence through speech. This is done by “simply by commanding step by step that the cosmic order come into being.” Among the living beings G-d creates are humans, represented by Adam and Eve. Initially, Adam and Eve lived under G-d’s protection in a state of harmony and innocence. However, they transgressed by eating the fruit of the “tree of knowing good and evil,” an act that led to their expulsion from the Garden of Eden. Their actions casted them into a world of toil, mortality, and human suffering. As one historian has observed, “the very act of learning the difference between good and evil brought suffering into the world.”
| Genesis 1:1–2:3: Creation God said, “Let the earth bring forth every kind of living creature: cattle, creeping things, and wild beasts of every kind.” And it was so. God made wild beasts of every kind and cattle of every kind, and all kinds of creeping things of the earth. And God saw that this was good. And God said, “Let us make man in our image, after our likeness. They shall rule the fish of the sea, the birds of the sky, the cattle, the whole earth, and all the creeping things that creep on earth.” And God created man in His image, in the image of God He created him; male and female He created them. God blessed them and God said to them, “Be fertile and increase, fill the earth and master it; and rule the fish of the sea, the birds of the sky, and all the living things that creep on earth.” God said, “See, I give you every seed-bearing plant that is upon all the earth, and every tree that has seed-bearing fruit; they shall be yours for food. And to all the animals on land, to all the birds of the sky, and to everything that creeps on earth, in which there is the breath of life, [I give] all the green plants for food.” And it was so. And God saw all that He had made, and found it very good. And there was evening and there was morning, the sixth day. The heaven and the earth were finished, and all their array. On the seventh day God finished the work that he had been doing, and He ceased on the seventh day from all the work that He had done. And God blessed the seventh day and declared it holy, because on it God ceased from all the work of creation that He had done. Such is the story of heaven and earth when they were created. |

The early texts of the Tanakh emphasize recurring human failures, or “depictions of human beings’ inability to live as they should.” This theme is not only illustrated through the transgression of Adam and Eve but also through the actions of their children, Cain and Abel. Cain, the first human born, became the first to commit murder when he killed his brother, violating the “G-d-endowed sanctity of human life.” For many historians, this act of violence also reflects deeper symbolic tensions between sedentary and nomadic lifeways: Cain was a farmer, while Abel was a shepherd.
The cycle of human shortcomings continues with increasing wickedness, leading to the first covenant recorded in the Tanakh: the covenant between G-d and Noah. In response to humanity’s corruption, G-d unleashed a flood to cleanse the earth, sparing only Noah, his family, and a remnant of living creatures. Through this covenant, G-d promised never to destroy the earth by flood again, establishing a pivotal moment in the relationship between G-d and humanity.
| Genesis 17:1–22: First Covenant God blessed Noah and his sons, and said to them, “Be fertile and increase, and fill the earth. The fear and the dread of you shall be upon all the beasts of the earth and upon all the birds of the sky—everything with which the earth is astir—and upon all the fish of the sea; they are given into your hand. Every creature that lives shall be yours to eat; as with the green grasses, I give you all these. You must not, however, eat flesh with its life-blood in it. But for your own life-blood I will require a reckoning: I will require it of every beast; of man, too, will I require a reckoning for human life, of every man for that of his fellow man! Whoever sheds the blood of man, By man shall his blood be shed; For in His image Did God make man. Be fertile, then, and increase; abound on the earth and increase on it.” And God said to Noah and to his sons with him, “I now establish My covenant with you and your offspring to come, and with every living thing that is with you—birds, cattle, and every wild beast as well—all that have come out of the ark, every living thing on earth. I will maintain My covenant with you: never again shall all flesh be cut off by the waters of a flood, and never again shall there be a flood to destroy the earth.” |
Finally, there is the story of the Tower of Babel, a pivotal moment of defiance against G-d’s will. Humanity, united by a single language, sought to build a tower reaching the heavens, an act symbolizing human pride and ambition. In response, G-d disrupted their efforts by confounding their language, causing them to speak in different tongues. This act scattered humanity across the earth and marked the origin of linguistic and cultural diversity, as well as a reminder of the limits of human ambition when it opposes divine will.
The second covenant recorded in the Tanakh is between G-d and Abram (later renamed Abraham). While the text does not explicitly state why Abram was chosen, it suggests that, like Noah, he was a righteous man who found favor with G-d. Abram, who came from the city-state of Ur of the Chaldees in Mesopotamia, was instructed by G-d to leave his homeland and migrate to the land of Canaan. There, he was promised that his descendants would inherit the land and become a great nation. This covenant marked the beginning of a unique and enduring relationship between G-d and the people of Israel, rooted in faith, obedience, and divine promise.
| Genesis 17:1–22: Second Covenant When Abram was ninety-nine years old, the Lord appeared to Abram and said to him, “I am El Shaddai [God heeds]. Walk in My ways and be blameless. I will establish My covenant between Me and you, and I will make you exceedingly numerous.” Abram threw himself on his face; and God spoke to him further, “As for Me, this is My covenant with you: You shall be the father of a multitude of nations. And you shall no longer be called Abram, but your name shall be Abraham, for I make you the father of a multitude of nations. I will make you exceedingly fertile, and make nations of you; and kings shall come forth from you. I will maintain My covenant between Me and you, and your offspring to come, as an everlasting covenant throughout the ages, to be God to you and to your offspring to come. I assign the land you sojourn in to you and your offspring to come, all the land of Canaan, as an everlasting holding. I will be their God.” God further said to Abraham, “As for you, you and your offspring to come throughout the ages shall keep My covenant. Such shall be the covenant between Me and you and your offspring to follow which you shall keep: every male among you shall be circumcised. You shall circumcise the flesh of your foreskin, and that shall be the sign of the covenant between Me and you. And throughout the generations, every male among you shall be circumcised at the age of eight days. As for the homeborn slave and the one bought from an outsider who is not of your offspring, they must be circumcised, homeborn and purchased alike. Thus shall My covenant be marked in your flesh as an everlasting pact. And if any male who is uncircumcised fails to circumcise the flesh of his foreskin, that person shall be cut off from his kin; he has broken My covenant.” And God said to Abraham, |
After settling in Canaan, Abram received G-d’s covenant, which promised that his descendants would inherit the land and become a great nation. As a sign of this covenant, G-d instituted the ancient rite of circumcision, to be performed on every baby boy within the first week of life. G-d also gave Abram a new name, Abraham, symbolizing the elevated role Abraham would play in the divine plan.
Isaac, the son and heir of Abraham, would later father Jacob, whose name was changed to Israel. In the next generation, Jacob’s (Israel) four wives bore him twelve sons and one daughter. These twelve sons became the patriarchs of the twelve tribes of Israel, forming the foundation of the Israelite nation as foretold in G-d’s covenant with Abraham.

A famine eventually forced Jacob and his family to leave the land of Canaan and seek refuge in Egypt. During their time in Egypt, Jacob’s descendants were reduced to slavery, enduring years of hardship and suffering. In response to their plight, G-d sent Moses to lead them out of bondage. Through Moses, the descendants of Jacob became the free people of Israel, a nation composed of twelve tribes named after Jacob’s twelve sons.
After their liberation, Moses guided the Israelites into the Sinai desert, where they experienced a profound encounter with the divine. There, G-d’s voice spoke directly to them, delivering the laws by which they were to live. These laws formed the basis of the third covenant, through which Israel was established as G-d’s chosen nation, bound by divine law and united under His protection.
| Exodus 19, 20:1–17: Third Covenant On the third new moon after the Israelites had gone forth from the land of Egypt, on that very day, they entered the wilderness of Sinai. Having journeyed from Rephidim, they entered the wilderness of Sinai and encamped in the wilderness. Israel encamped there in front of the mountain, and Moses went up to God. The Lord called to him from the mountain, saying, “Thus shall you say to the house of Jacob and declare to the children of Israel: ‘You have seen what I did to the Egyptians, how I bore you on eagles’ wings and brought you to Me. Now then, if you will obey Me faithfully and keep My covenant, you shall be My treasured possession among all the peoples. Indeed, all the earth is Mine, but you shall be to Me a kingdom of priests and a holy nation.’ These are the words that you shall speak to the children of Israel.” God spoke all these words, saying: “I the Lord am your God who brought you out of the land of Egypt, the house of bondage: You shall have no other gods besides Me. “You shall not make for yourself a sculpted image, or any likeness of what is in the heavens above, or on the earth below, or in the waters under the earth. You shall not bow down to them or serve them for I the Lord your God am an impassioned God, visiting the guilt of the parents upon the children, upon the third and upon the fourth generations of those who reject Me, but showing kindness to the thousandth generation of those who love Me and keep My commandments. “You shall not swear falsely by the name of the Lord your God; for the Lord will not clear one who swears falsely by His name. “Remember the sabbath day and keep it holy. Six days you shall labor and do all your work, but the seventh day is a sabbath of the Lord your God: you shall not do any work—you, your son or daughter, your male or female slave, or your cattle, or the stranger who is within your settlements. For in six days the Lord made heaven and earth and sea, and all that is in them, and He rested on the seventh day; therefore the Lord blessed the sabbath day and hallowed it. “Honor your father and your mother, that you may long endure on the land that the Lord your God has assigned to you. “You shall not murder. “You shall not commit adultery. “You shall not steal. “You shall not bear false witness against your neighbor. “You shall not covet your neighbor’s house; you shall not covet your neighbor’s wife, or his male or female slave, or his ox or his ass, or anything that is your neighbor’s.” |
Over time, the twelve tribes of Israel were unified into a single kingdom. However, the stability of this kingdom was disrupted when ten of the tribes rebelled against the royal family, resulting in the division of Israel into two kingdoms. The northern kingdom retained the name Israel, while the southern kingdom, Judah, remained loyal to the royal family.

The kingdom of Israel was eventually destroyed by the Assyrian Empire in 722 B.C.E., leading to the displacement of its people. Judah, ruled by the descendants of David, faced a similar fate when it was conquered by the Babylonian Empire in 587 B.C.E. During this conquest, the Temple built by Solomon in Jerusalem was destroyed, and Judah’s leadership was exiled to Babylon, marking the beginning of the Jewish Diaspora.
It was during this period of exile that historians believe the Torah gained prominence as the central guide for Jewish religious beliefs and practices. In time, a group of exiles returned to the land of Israel and worked to rebuild a holy community centered on devotion to G-d’s word and the teachings of Moses. For many, this return marked the end of the Diaspora, though others remained scattered throughout the ancient world, continuing the broader dispersion of the Jewish people.
The arrival of Alexander the Great in the region and the subsequent rise of the Seleucid Empire after his death brought Judea into conflict with this Hellenistic kingdom. The Seleucid rulers sought to impose Hellenistic culture and practices, creating tension with the Jewish population, which resisted these influences. This conflict eventually escalated into open rebellion, most notably during the Maccabean Revolt.

A new era of conflict emerged with the rise of the Roman Empire, which supplanted the Seleucid Kingdom as the dominant power in the region. Under Roman rule, Judea became a province, and tensions persisted as the Jewish population struggled to maintain their religious and cultural identity under foreign governance.
The narrative just given “establishes certain conceptions that remained central to the emerging Jewish religion.” For example:
| 1. The narrative identifies “the G-d of the Jews as the creator and sole ruler of the universe.” 2. The narrative “asserts Israel’s claim to a special relationship with this God and explains how this relationship came to be.” 3. The narrative “depicts the Jewish way of life and the Jewish national homeland as gifts from G-d and gateways to holiness for those who abide by G-d’s demands and teachings.” 4. The narrative “contains a stark warning that those who depart from those teachings or who resist those demands unavoidably bring down disaster for themselves and those around them. ” |
Scholars will likely never be able to trace the precise development of monotheism with complete accuracy. However, the impact of monotheism, the ancient Hebrews, and the Tanakh is undeniable, particularly in the rise of Judaism. This foundational belief system would go on to shape two other major monotheistic religions: Christianity and Islam. Together, these three faiths, sharing a common spiritual ancestry rooted in the figure of Abraham, are collectively referred to as the Abrahamic religions. The shared heritage of these traditions highlights their interconnected histories, while their distinct interpretations of faith have profoundly shaped the religious and cultural landscapes of the world.

One final note before we move on. Sects within Judaism were not uncommon during its early period. The Jewish historian Flavius Josephus (c. 37–100 C.E.), in his work The Antiquities of the Jews, identifies four dominant sects: the Pharisees, the Sadducees, the Essenes, and the Zealots. These groups differed significantly in their interpretations of Jewish law, their responses to foreign rule, and their expectations of the Messiah, reflecting the diversity of Jewish thought in the Second Temple period.
Table 5: The Dominant Sects in Ancient Judaism
| Group | Who They Were | Main Beliefs |
|---|---|---|
| Pharisees | A popular movement of religious teachers and scholars. | Believed in both the Written Torah and the Oral Law; believed in the resurrection of the dead, angels, and divine judgment. Emphasized strict observance of Jewish law in everyday life. |
| Sadducees | Priestly and aristocratic class centered on the Temple in Jerusalem. | Accepted only the Written Torah as authoritative. Rejected the resurrection, angels, and the Oral Law. Focused on Temple worship and sacrifices. |
| Essenes | A separatist Jewish community, possibly including the group at Qumran. | Practiced communal living, ritual purity, prayer, and strict discipline. Expected God to soon establish His kingdom. Many scholars associate them with the Dead Sea Scrolls. |
| Zealots | A militant Jewish nationalist movement. | Believed that God alone should rule Israel and that armed resistance against foreign rulers was a religious duty. |
DO NOT THINK I HAVE COME TO ABOLISH THE LAW
Christianity, like Judaism, traces its spiritual lineage back to Moses, Abraham, and ultimately Adam and Eve. The canon of the New Testament contains the foundational Christian scriptures, but it is important to note that numerous non-canonical Christian writings also exist. This diversity is partly due to the theological conflicts and varying interpretations of Christian beliefs that arose among early Christian communities. It was not until around 367 C.E. that the Christian Bible, as it appears today, is first mentioned in historical sources. This reference, found in a letter by Athanasius, the Bishop of Alexandria, reflects the gradual process of canon formation as the early Church sought to define orthodoxy and unify the faith amidst its diversity.

The dominant theme in the teachings of Jesus is the kingdom of God. Central to his message was the idea of an imminent apocalypse (a catastrophic end of the world) followed by God’s judgment, where individuals would be rewarded or punished based on their actions. The teachings of Jesus were not concerned with politics, such as subservience to Rome, nor with theology or doctrinal debate. Instead, his focus was on morality and ethical living. Unlike theologians who discussed doctrine or rabbis who interpreted the law, Jesus communicated through simple, relatable stories and parables, using metaphorical and figurative language to illustrate how people should live and treat one another.
Table 6: Judaism and Christianity
| Category | Ancient Judaism | Early Christianity |
|---|---|---|
| Approximate Origins (Year) | Developed gradually between c. 1800–1200 BCE with the Patriarchs and the Sinai Covenant; reshaped during the Babylonian Exile (586–539 BCE) and Second Temple period (516 BCE–70 CE). | Began in c. 30–33 CE with the ministry, death, and resurrection of Jesus of Nazareth in Roman Judea. Expanded rapidly throughout the Roman Empire during the 1st century CE. |
| Cause for Its Creation | Emerged from God’s covenant with Abraham and later with Israel through Moses, establishing Israel as God’s covenant people under the Torah. | Originated from the belief that Jesus was the promised Jewish Messiah whose death and resurrection inaugurated a New Covenant and fulfilled God’s promises to Israel. |
| Founder / Prophet / Sage | Abraham (patriarch), Moses (lawgiver), and prophets including Isaiah, Jeremiah, Ezekiel, Elijah, and others. Later sages included Ezra, Hillel, and Shammai. | Jesus of Nazareth (Messiah, teacher, and Son of God), followed by the Twelve Apostles, especially Peter, James, and Paul, who spread Christianity throughout the Mediterranean world. |
| Sacred Texts | Tanakh (Hebrew Bible): Torah, Prophets (Nevi’im), and Writings (Ketuvim). Oral traditions later became the Mishnah and Talmud. | Hebrew Scriptures (Old Testament) plus the developing New Testament, including the four Gospels, Acts, the Pauline Letters, General Epistles, and Revelation. |
| Core Premises / Beliefs | One G-d, covenant between G-d and Israel, Torah is G-d’s revealed law, ethical living, justice, holiness. Israel is G-d’s chosen people. awaited the coming Messiah | One God revealed as Father, Son, and Holy Spirit (understanding developed over time). Jesus is the promised Messiah and Son of God. Jesus’ death and resurrection conquered sin and death. salvation is available to Jews and gentiles. the Kingdom of God has begun through Christ and will be fully realized at his return |
| Liberation / Salvation | Liberation is primarily understood as God’s deliverance of Israel (especially the Exodus). Individuals live faithfully through covenant obedience, repentance (teshuvah), worship, and observance of the Torah. | Salvation is understood as deliverance from sin and death through Jesus Christ. It is received by God’s grace through faith, repentance, baptism, and participation in the Christian community. Eternal life is promised through Christ’s resurrection. |
| Primary Religious Practices | Temple sacrifices (until 70 CE), prayer, Sabbath observance, circumcision, dietary laws (kosher), festivals, Torah study, charity (tzedakah), and obedience to the commandments. | Baptism, the Lord’s Supper (Eucharist), prayer, preaching, worship, charity, communal fellowship, reading Scripture, missionary work, and moral discipleship. Most Gentile Christians did not observe circumcision or the full Mosaic Law. |
| Ultimate Goal | To live faithfully within God’s covenant, become a holy people, and anticipate the coming Messianic Age and restoration of Israel. | To follow Jesus as Lord, participate in God’s Kingdom, receive eternal life through the resurrection, and live in communion with God forever. |
What made Jesus unique was his emphasis on the kingdom of God as the foundation for ethical behavior. He taught that moral acts such as repentance, love, charity, and nonviolence are God’s requirements for acceptance into the kingdom. In this way, he reframed traditional religious teachings, prioritizing a life of moral action over ritual or legal adherence.

In the early history of Christianity, there was no clear dividing line between Judaism and the emerging Christian movement. Jesus of Nazareth and his followers viewed themselves as part of Judaism, adhering to its religious discipline and traditions. This is evident in Matthew 5:17, where Jesus is recorded as saying, “Do not think I have come to abolish the Law or the Prophets; I have come not to abolish but to fulfill.” Initially, the followers of Jesus were seen as a sect within Judaism rather than as adherents of a separate religion.
So why did Judaism and Christianity eventually diverge? From the Jewish perspective, the split occurred when Jesus, followed by Paul, introduced a new interpretation of Judaism. It was one that abandoned certain commandments and borrowed core elements of Jewish tradition while adding what many Jews considered foreign or incorrect ideas. Central to this divergence was the Christian claim that Jesus was the Messiah and even the incarnation of God. This was a concept that contradicted Jewish teachings about the nature of the Messiah and the oneness of God. Over time, these theological differences, combined with the Christian movement’s outreach to non-Jews (Gentiles), led to Christianity emerging as a distinct monotheistic religion.

From the Christian perspective, Jesus “perfected” Judaism, bringing it to its intended fulfillment. However, Christians believed that the majority of Jews failed to recognize this transformation and continued to follow what Christians viewed as an obsolete form of the religion. As a result, Christianity was eventually seen as a heretical sect within Judaism.

Over time, Christianity grew beyond its Palestinian origins and Jewish framework, gradually becoming an independent religion. By 60 C.E., tensions between Jewish leadership and the emerging Christian movement had intensified, leading to a decisive split. One of the most influential figures driving this separation was Paul of Tarsus (c. 4–64 C.E.), a vigorous proponent of expanding Christianity to a broader audience. Paul argued that adherence to Mosaic law was no longer necessary for salvation and that Gentile converts should not be required to follow Jewish customs, such as circumcision or dietary laws. This position marked a significant departure from Judaism and helped Christianity establish itself as a distinct, universal faith.

As one historian has emphasized, the conflict between Judaism and early Christianity was not purely doctrinal. It also centered on questions of identity. Paul’s position, which downplayed the necessity of Mosaic law, “proved incompatible with the way that Jews understood themselves as a people or a community.” Mosaic law, along with its accompanying customs and rituals, was integral to the shaping of Jewish identity. For Jews, adherence to these laws was not merely a religious obligation but a defining element of their communal and cultural life, setting them apart as G-d’s chosen people. By suggesting that such laws were no longer essential, Paul’s teachings challenged the very framework through which Jews understood their relationship with G-d and their collective identity.

Due to the lack of unity among early Christians, “interpretations of Jesus and his message varied greatly among the new followers.” What was clear to most early Christians, however, was their belief in Jesus as the “crucified and risen Messiah who would return from heaven at any moment to begin an apocalyptic reign.” What remained unclear, and sparked one of the earliest and most significant debates within the movement, was the precise nature of Jesus. Was he divine, human, or some combination of the two? This theological question became a central point of contention among early Christians, as illustrated immediately below, and led to diverse interpretations that shaped the development of Christian doctrine over time.
Table 6: The Christological Debate
| Group | Who They Were | View of Jesus | Relationship to Judaism | Historical Outcome |
|---|---|---|---|---|
| Jewish-Christian Adoptionists | Early Jewish followers of Jesus who continued to observe the Mosaic Law. | Jesus was a fully human Messiah who was adopted by God (often at his baptism) and empowered by the Holy Spirit. They rejected Jesus’ pre-existence and divinity. | Strongly maintained Jewish identity, including circumcision, dietary laws, and Sabbath observance. | Gradually disappeared by the 4th–5th centuries as Christianity became predominantly Gentile. |
| Marcionite Christians | Followers of Marcion of Sinope (c. 85–160 CE), who sought to separate Christianity completely from Judaism. | Jesus was the divine Son of the loving God and only appeared to be human (Docetic tendencies). | Rejected Judaism and denied that Christianity fulfilled the Jewish Scriptures. | Declared heretical by the Church, though Marcionite communities survived for several centuries. |
| Gnostic Christians | Diverse movements emphasizing secret (gnosis, “knowledge”) as the path to salvation. | Jesus was a divine revealer who came to awaken humanity to its true spiritual identity. Many denied that Christ truly suffered physically (Docetism). | Generally viewed the God of the Hebrew Bible as the inferior creator rather than the supreme God. | Condemned as heretical; most movements disappeared by the early Middle Ages. Many writings were rediscovered at Nag Hammadi (Egypt) in 1945. |
| Proto-Orthodox Christians | The mainstream movement that eventually became orthodox Christianity and developed into the Catholic, Orthodox, and later Protestant traditions. | Jesus is fully God and fully human, the eternal Son of God, whose death and resurrection bring salvation. | Saw Christianity as the fulfillment of God’s promises to Israel while generally not requiring observance of the Mosaic Law. | Became the dominant form of Christianity after the 4th century and shaped the historic Christian creeds and biblical canon. |
In Closing
It was during the Patristic Period that Christian doctrine was formalized, and the final version of the New Testament was canonized. This critical era in Christian history saw debates and decisions that would define orthodoxy and the structure of Christian scripture. We will explore this topic in greater detail in a later module.

Holidays
From an early time, the Israelite religion had developed a calendar of important days to be observed. Of these, the earliest is Passover (Pesach), an annual celebration of Israel’s escape from Egyptian bondage. Yom Kippur, the annual Day of Atonement became the holiest day of the year. Over the course of time, the most striking feature of the Israelite calendar turned out to be the Sabbath, “the weekly day when productive labor was forbidden.”
