The question of the relationship between Jesus’s Jewish identity and the emergence of Catholicism addresses the historical and theological development of Christianity. Jesus, born and raised Jewish, lived his life within the context of first-century Judaism. His teachings, actions, and self-understanding were deeply rooted in Jewish tradition and scripture. However, the early followers of Jesus, initially all Jewish, gradually began to include Gentiles (non-Jews) into their community. This inclusion, and the debates it generated regarding adherence to Jewish law, marked a turning point in the evolution of the Christian faith.
The separation between Judaism and Christianity was not a singular event but a complex process spanning several centuries. Key events contributing to this divergence include the destruction of the Second Temple in 70 CE, which significantly altered Jewish religious practice, and the growing influence of Pauline theology, which emphasized faith in Christ over strict adherence to the Mosaic Law. The Council of Jerusalem, described in the Book of Acts, addressed the issue of Gentile converts and their obligations to Jewish law, setting a precedent for a more inclusive, less legalistic approach. Over time, Christian practices and beliefs became increasingly distinct from those of Judaism, culminating in the establishment of a separate religious identity.
