Many Christians assume that Christianity and Judaism separated almost immediately after the resurrection of Yeshua. In this common understanding, the apostles left Judaism behind, established a new religion called Christianity, and the Church quickly became something distinct from Jewish life.
Messianic Judaism is a movement of Jewish people who believe that Yeshua (Jesus) is the promised Messiah of Israel while continuing to embrace their Jewish identity, heritage, and connection to the Jewish people. It seeks to live out faith in the Messiah within a Jewish framework rather than abandoning Jewish life and culture.
Scriptural unity never required the erasure of Jewish identity. In Messiah, Jews and Gentiles are brought into one body through peace, not through flattening what God has chosen to distinguish.
