We heard Matthew’s account of Jesus’ baptism last Sunday, on the feast of the Baptism of the Lord. Today, we hear John the Baptist’s testimony about Jesus as found in John’s Gospel. John’s Gospel differs from the other Gospels because John does not describe Jesus’ baptism by John the Baptist. Instead, John the Baptist announces that he knows that Jesus is the Son of God. In today’s reading, John the Baptist sees Jesus approaching and cries out, giving witness about who Jesus is. In John’s testimony he says that he saw the Spirit descend upon Jesus. By this sign, John the Baptist knew that Jesus was the one who is to come after him. John the Baptist uses two titles for Jesus that are familiar to us. John calls Jesus the “Lamb of God” and the “Son of God.” By using these titles, John the Baptist identifies Jesus’ ultimate purpose: to redeem sinful humanity. John the Baptist’s testimony about Jesus clearly distinguishes John’s baptism from the Baptism that Jesus will inaugurate. John baptizes with water; Jesus will baptize with the Holy Spirit. John also puts his practice of baptism in the context of Jesus’ ministry. The purpose of John’s baptism was to make Jesus known to Israel. John the Baptist’s sense of purpose is clearly identified in this reading: he baptized in order to prepare for and make known the ministry of the One who was to follow. John’s witness is an excellent example of what it means to be a disciple. By our Baptism, we are called to make Jesus known to all the world by our words and by the witness of our lives.
