What significant event marked a major break in tradition for Jews and Christians?

The significant event that marked a major break in tradition for Jews and Christians is best identified as the Kiss of Peace. This practice, which involves the exchange of a kiss as a sign of peace and unity among believers, symbolizes a fundamental shift in the relationship dynamics within the Christian community as they began to distinguish themselves from Jewish customs.

The Kiss of Peace represents the inclusive nature of Christianity and the emergence of a new communal identity that transcended previous cultural and ritual boundaries, which were primarily rooted in Jewish tradition. This gesture of fellowship among early Christians emphasized their unity in Christ and was emblematic of the new covenant established through Jesus.

While the Last Supper, Breaking of Bread, and Good Friday Service are all significant in the context of Christian tradition and theology, none epitomize the break from Jewish tradition as distinctly as the practice of the Kiss of Peace does, as it directly reflects the evolving nature of Christian liturgy and community life in the wake of Jewish separation. The Kiss of Peace highlights the transition towards new worship practices that prioritize community and relational aspects of faith in Christ beyond the confines of Jewish rituals.
