The Christmas season, celebrating the self-revelation of God through Jesus, comes to an end with the feast of the Baptism of Our Lord. Christmas is the feast of God's self-revelation to the Jews and Epiphany celebrates God's self-revelation to the Gentiles. At the Baptism in Jordan, Christ reveals himself to repentant sinners. The Baptism of the Lord Jesus is the great event celebrated by the Eastern churches on the feast of Epiphany because it is the occasion of the first public revelation of all the Three Persons in the Holy Trinity and the official revelation of Jesus as the Son of God to the world by God the Father.
