Today the Church celebrates the Feast of the Baptism of Our Lord. This brings to an end the season of Christmas. The Church recalls Our Lord's second manifestation or epiphany which occurred on the occasion of His baptism in the Jordan. Jesus descended into the River to sanctify its waters and to give them the power to beget sons of God. The event takes on the importance of a second creation in which the entire Trinity intervenes.
Many of the incidents which accompanied Christ's baptism are symbolical of what happened at our Baptism. At Christ's baptism the Holy Spirit descended upon Him; at our Baptism the Trinity took its abode in our soul. At His baptism Christ was proclaimed the "Beloved Son" of the Father; at our Baptism we become the adopted sons of God. At Christ's baptism the heavens were opened; at our Baptism heaven was opened to us. At His baptism Jesus prayed; after our Baptism we must pray to avoid actual sin.
Now, in the mystery of Christ’s Baptism in the Jordan River, we again encounter and represent the truth of the Lord’s incarnation and His manifestation as the Christ. Jesus’ Baptism is in fact His definitive manifestation as the Messiah or Christ to Israel, and as the Son of the Father to the entire world. Here we find the dimension of the Epiphany which was His manifestation to all nations. The Father’s voice from heaven shows that Jesus of Nazareth is the eternal Son and the descent of the Holy Spirit in the form of a dove shows the Trinitarian nature of the Christian God. The true and unique God, Father, Son, and Holy Spirit, shows Himself in Christ, through Him, with Him and in Him.
