Rev 22, 16 I am the root and offspring of David

(Rev 22, 16) I am the root and offspring of David

[16] "I, Jesus, sent my angel to give you this testimony for the churches. I am the root and offspring of David, the bright morning star."

(CCC 437) To the shepherds, the angel announced the birth of Jesus as the Messiah promised to Israel: "To you is born this day in the city of David a Savior, who is Christ the Lord (Lk 2:11). From the beginning he was "the one whom the Father consecrated and sent into the world", conceived as "holy" in Mary's virginal womb (Jn 10:36; cf. Lk 1:35). God called Joseph to "take Mary as your wife, for that which is conceived in her is of the Holy Spirit," so that Jesus, "who is called Christ," should be born of Joseph's spouse into the messianic lineage of David (Mt 1:20; cf. 1:16; Rom 1:1; 2 Tim 2:8; Rev 22:16). (CCC 528) The Epiphany is the manifestation of Jesus as Messiah of Israel, Son of God and Savior of the world. The great feast of Epiphany celebrates the adoration of Jesus by the wise men (magi) from the East, together with his baptism in the Jordan and the wedding feast at Cana in Galilee (Mt 2:1; cf. LH, Epiphany, Evening Prayer II, antiphon at the Canticle of Mary). In the magi, representatives of the neighboring pagan religions, the Gospel sees the first-fruits of the nations, who welcome the good news of salvation through the Incarnation. The magi's coming to Jerusalem in order to pay homage to the king of the Jews shows that they seek in Israel, in the messianic light of the star of David, the one who will be king of the nations (Cf. Mt 2:2; Num 24:17-19; Rev 22:16). Their coming means that pagans can discover Jesus and worship him as Son of God and Savior of the world only by turning towards the Jews and receiving from them the messianic promise as contained in the Old Testament (Cf. Jn 4 22; Mt 2:4-6). The Epiphany shows that "the full number of the nations" now takes its "place in the family of the patriarchs", and acquires Israelitica dignitas (St. Leo the Great, Sermo 3 in epiphania Domini 1-3, 5: PL 54, 242; LH, Epiphany, OR; Roman Missal, Easter Vigil 26, Prayer after the third Reading) (are made "worthy of the heritage of Israel").
