Jesus was unmistakably a Jew by birth, law, practice, and identity: born to Jewish parents (Mary and Joseph) in Judea and raised in Galilee, he is recorded as legally descended from David of the tribe of Judah (genealogies in Matthew 1 and Luke 3); he was circumcised on the eighth day and presented in the Temple with the prescribed offering (Luke 2:21–24; cf. Leviticus 12); he attended synagogue regularly and read Scripture publicly (Luke 4:16–21); he was addressed as “Rabbi” (John 1:38) and explicitly affirmed the Shema and the authority of Torah (“I have not come to abolish the Law,” Matthew 5:17; Mark 12:29); he kept Jewish festivals—Passover (Luke 2:41; Mark 14:12–16), Tabernacles/Booths (John 7:2, 10), and Dedication/Hanukkah (John 10:22); he wore tzitzit (ritual fringes) on his garment (Matthew 9:20; cf. Numbers 15:38); he observed Sabbath (while disputing certain interpretations; Mark 2:27); he spoke Hebrew/Aramaic phrases (“Talitha koum,” “Eli, Eli…,” Mark 5:41; Matthew 27:46); his given name Yeshua is the common Hebrew form of Joshua; his mission is framed as to “the lost sheep of Israel” (Matthew 15:24); and even in death the placard over the cross read “King of the Jews” (John 19:19). All of this—lineage, rites, language, titles, worship, dress, festivals, and self-understanding—locates Jesus squarely within first-century Judaism.
