The early Christian movement emerged within the complex religious and cultural landscape of Second Temple Judaism, where the Hebrew Scriptures—the Old Testament in Christian terminology—played a central and authoritative role. For the early followers of Jesus, these sacred texts were not merely historical documents or legal codes but the living testimony of God's covenantal dealings with Israel. From the outset, the early Christians were engaged in a profound hermeneutical endeavor: to interpret the life, death, and resurrection of Jesus of Nazareth as the culmination of the divine narrative embedded within the Torah, the Prophets, and the Writings. This interpretative effort was not only theological but also missional, as the early Christians sought to proclaim Jesus as the fulfillment of Israel's messianic hope to both Jewish and Gentile audiences. The historical context is indispensable to understanding the use of the Old Testament in the early Christian tradition. The Jewish milieu of the first century was characterized by diverse interpretations of the Scriptures. Groups such as the Pharisees, Sadducees, Essenes, and Zealots had differing views on key theological concepts such as the resurrection, messianism, and the nature of God's covenant with Israel. The discovery of the Dead Sea Scrolls at Qumran, for instance, reveals a community that saw itself as the "righteous remnant" awaiting divine vindication, interpreting the prophecies of Isaiah and the Psalms through an apocalyptic lens. Into this context stepped Jesus, who positioned himself as the embodiment of the promises made to Israel, declaring in passages such as Luke 4:16-21 that he had come to fulfill the prophetic announcement of liberation and restoration.
