The Emergence of Christianity

The Birth of Monotheism: Cultural Fusion and the Rise of One God

By Alan Marley

Monotheism—the belief in a single, all-powerful deity—is often viewed as a theological revolution. But history suggests it was not a sudden revelation; rather, it was an evolution rooted in centuries of cultural contact, religious reform, and political upheaval. The rise of monotheism in the ancient Near East, especially among the Israelites, represents a gradual process of refinement, merging traditional beliefs with new theological insights brought about by conquest, exile, and survival.


Early Israelite Religion: Henotheism, Not Monotheism

The earliest form of Israelite religion was not strictly monotheistic. Scholars widely agree that the Israelites originally practiced henotheism—the worship of one god without denying the existence of others (Smith, 2002). Numerous passages in the Hebrew Bible suggest the presence and acceptance of other deities. For example, Exodus 15:11 asks, “Who is like you among the gods, O LORD?” This rhetorical question implies that other gods were believed to exist, even if Yahweh was considered supreme.

Psalm 82 is another key example. In it, God presides over a divine council and passes judgment on other gods. The passage concludes with a declaration that Yahweh will “inherit all the nations” (Psalm 82:8), indicating a shift toward universal rule—but not yet exclusive divinity.


The Canaanite Connection: Yahweh, El, and Baal

Archaeological and textual evidence reveals significant theological borrowing from Canaanite religion, particularly in the figures of El, Baal, and Asherah. The name El, for instance, appears frequently in Hebrew names—Israel, Betel, Ezekiel—indicating early reverence or syncretism (Day, 2000). Some biblical passages even refer to Yahweh as "El Elyon" (God Most High), suggesting a blending of identities (Genesis 14:18–20).

Baal, the Canaanite storm god, was both a rival and influence on Israelite thought. The prophetic texts denounce Baal worship repeatedly, which ironically confirms how widespread his worship was among Israelites (Hosea 2:13; 1 Kings 18). These denunciations mark the struggle to define Yahweh not just as superior, but as the only legitimate deity.


The Babylonian Exile: Crisis and Theological Shift

The Babylonian exile (586–539 BCE) was a turning point. The destruction of the Jerusalem Temple and the deportation of Israel's elite to Babylon forced a theological crisis. Without a temple, priesthood, or national autonomy, the Israelites reexamined their covenant with Yahweh. Many scholars argue that this period gave rise to pure monotheism as a response to national catastrophe (Finkelstein & Silberman, 2001).

During exile, the biblical texts underwent significant editing and compilation. The Deuteronomistic history (Deuteronomy through Kings) reframes Israel’s past as a series of covenantal failures—idolatry, injustice, disobedience—culminating in divine punishment. This reinterpretation not only reinforced exclusive worship of Yahweh but portrayed Him as the only true god who acts on behalf of all nations.


he Influence of Zoroastrianism and Persian Ideals

While in exile and under later Persian rule, Israelites encountered Zoroastrianism, a monotheistic-leaning religion with cosmic dualism and a focus on divine justice. The figure of Ahura Mazda, the single wise god, may have influenced emerging Jewish ideas of Yahweh as a universal moral judge, rather than a tribal deity (Boyce, 1979).

Persian imperial ideology also aligned with Israel’s theological evolution. The Persian kings allowed the Jews to return and rebuild their temple, framing their monotheistic worship as beneficial to imperial harmony. This further solidified the shift toward exclusive Yahweh worship as part of a new national identity.

Conclusion: Monotheism as Evolution, Not Invention

The birth of monotheism was not a spontaneous event. It was forged in the crucible of crisis, shaped by cultural exchange, and refined by centuries of theological development. What began as henotheistic worship of Yahweh within a pantheon evolved into the foundational principle of Judaism: “Hear, O Israel: The LORD our God, the LORD is one” (Deuteronomy 6:4).

Understanding the human and historical context of monotheism does not diminish its spiritual significance—it enriches it, showing how deeply faith responds to history, survival, and the need for meaning.

The Emergence of Christianity: From Jewish Roots to a Global Faith

By Alan Marley

Christianity did not emerge in a vacuum. It arose from the rich religious soil of Second Temple Judaism, evolved in a Roman-occupied world, and was shaped by Jewish expectations, Hellenistic ideas, and the missionary zeal of early followers. What began as a small Jewish movement quickly grew into a global religion, propelled by charismatic leadership, theological innovation, and the sociopolitical climate of the ancient Mediterranean world.


Jesus in the Context of Judaism

Jesus of Nazareth lived and taught as a Jew. He preached in synagogues, debated Jewish law, and referenced Hebrew Scripture. His message of the "kingdom of God" was deeply rooted in the prophetic tradition—calling for repentance, justice, and the restoration of Israel (Sanders, 1993).

Jesus’ ethical teachings—such as loving one’s neighbor, forgiving enemies, and caring for the poor—resonated with Torah principles but often challenged prevailing religious authorities. He was not the first messianic figure in Jewish history, but his claim to fulfill prophecy and his crucifixion under Roman rule marked a turning point for his followers.


From Sect to Church: The Role of Paul

After Jesus’ death, a small community of followers proclaimed his resurrection. Initially centered in Jerusalem under leaders like Peter and James, the movement remained part of the Jewish religious framework. It was the work of Paul of Tarsus that transformed Christianity into a broader movement.

Paul’s letters—some of the earliest Christian writings—argued that faith in Jesus as the risen Christ was the true fulfillment of the covenant, and that Gentiles could join the movement without adhering to the full Mosaic law (Galatians 3:28). Paul’s theology emphasized grace over law, shifting the focus from ethnic identity to spiritual adoption.

This theological move was crucial: it allowed Christianity to spread beyond Jewish communities and become a religion of empire-wide relevance (Ehrman, 2004).


Hellenistic Influence and Theological Development

Christianity took root in the Hellenistic world, where Greek philosophy, language, and cosmology shaped religious thought. Early Christian theologians used Greek concepts—such as logos (reason or word), pneuma (spirit), and soul—to explain Jesus’ divinity and mission (Hurtado, 2005).

The Gospel of John, for example, opens with a cosmic Christ: “In the beginning was the Word (logos), and the Word was with God, and the Word was God” (John 1:1). This blending of Jewish messianism and Greek metaphysics helped Christianity gain traction in a philosophically curious world.

As Christianity expanded, creeds were developed to define belief. The doctrine of the Trinity, formalized in the fourth century, reflected efforts to reconcile Jesus’ divinity with monotheism, using philosophical tools available in the Roman world.


The Break from Judaism

By the end of the first century, tensions between Jewish Christians and mainstream Judaism had grown. The destruction of the Second Temple in 70 CE and subsequent Roman crackdowns on Jewish uprisings led to increased marginalization of Jesus-followers.

Writings like the Epistle to the Hebrews and the Gospel of Matthew begin to define Jesus as the new high priest, or the fulfillment of the Law—implicitly, and later explicitly, superseding it (Hebrews 8:6–13; Matthew 5:17).

Over time, Christianity's claim that Jesus was the universal messiah and divine Son of God placed it at odds with Jewish theology. The eventual formation of a Christian canon, priesthood, and liturgy completed the separation.


Conclusion: From Margins to Empire

Within three centuries, Christianity went from a fringe movement to the state religion of the Roman Empire. Its universal message, emphasis on spiritual equality, and adaptability to diverse cultures helped it thrive.

Yet its roots remain firmly Jewish—shaped by covenantal theology, prophetic ethics, and messianic hope. Understanding the emergence of Christianity as both a continuation and transformation of Judaism provides a more complete picture of its enduring power and global reach.
