The Nativity is feast of Light. The three-fold manifestation of this is seen in the Magi on the Epiphany, the theophany at Our Lord’s Baptism and the miracle at the wedding feast of Cana. Baptism is the official consecration of Christ as priest (although priest from Annunciation). Cana teaches about transubstantiation and the role of the Blessed Mother and prayer. Christ identifies Himself as our spouse and we are united in Holy Communion.
