The final Sunday of the Christmas season and the First Sunday of Ordinary Time are both the celebration of the Baptism of the Lord. In this scene, we encounter the adult Jesus for the first time, as He comes to the Jordan, where His cousin, John the Baptist, is baptizing in the river. The last time we saw Him was at the age of 10 when Mary and Joseph searched frantically for three days for him in Jerusalem.
All four Gospels begin the adult life and ministry at this point, His baptism. Luke’s account of the baptism, which we read from today, is very succinct— “When all the people were being baptized, Jesus was baptized too.” Then we are told that as He was praying, presumably after having been baptized, “heaven was opened and the Holy Spirit descended on Him in bodily form like a dove. And a voice came from heaven, ‘You are my Son, whom I love, with you I am well pleased.”
