The Feast of the Baptism of the Lord, celebrated on the Sunday after Epiphany, commemorates Jesus' baptism in the Jordan River by John the Baptist. This event marks the beginning of Jesus' public ministry and the manifestation of the Holy Trinity.
All four Gospels record Jesus' baptism. Matthew's account is particularly detailed:
"Then Jesus came from Galilee to the Jordan to John, to be baptized by him. But John would have hindered him, saying, 'I need to be baptized by you, and you come to me?" — Matthew 3:13-17
Jesus, being sinless, did not need John's baptism of repentance. Yet he submitted to baptism for several reasons:
The Baptism of the Lord is one of three traditional "Epiphany" events (along with the Magi's visit and the Wedding at Cana). It is a theophany—a manifestation of God:
After his baptism, Jesus went into the desert to fast and pray for forty days before beginning his public preaching. The baptism inaugurated this mission, anointing Jesus with the Spirit for the work of salvation.
Jesus' baptism prefigures and enables Christian baptism. What happened visibly at the Jordan happens invisibly in every baptism:
This feast is an appropriate time to renew our baptismal promises and give thanks for the gift of our own baptism, through which we were made members of Christ's Body.
