 Many Messianic Jews believe that Jesus is the Jewish Messiah and "God the Son" (one person of the Trinity), and that the Tanakh and New Testament are the authoritative scriptures.Salvation in Messianic Judaism is achieved only through acceptance of Jesus as one's savior, and Jewish laws or customs which are followed do not contribute to salvation.Belief in the messiahship of Jesus, his power to save, and his divinity are considered by Jewish authorities to be the defining distinctions between Christianity and Judaism.
