+ Jn 1: 29-34
The next day he saw Jesus coming toward him and said, “Behold, the Lamb of God, who takes away the sin of the world.
He is the one of whom I said, ‘A man is coming after me who ranks ahead of me because he existed before me.’
I did not know him, but the reason why I came baptizing with water was that he might be made known to Israel.”
John testified further, saying, “I saw the Spirit come down like a dove from the sky and remain upon him.
I did not know him, but the one who sent me to baptize with water told me, ‘On whomever you see the Spirit come down and remain, he is the one who will baptize with the holy Spirit.’
Now I have seen and testified that he is the Son of God.”

“The Lamb who takes away the sin of the world”
608 After agreeing to baptize him along with the sinners, John the Baptist looked at Jesus and pointed him out as the “Lamb of God, who takes away the sin of the world”. By doing so, he reveals that Jesus is at the same time the suffering Servant who silently allows himself to be led to the slaughter and who bears the sin of the multitudes, and also the Paschal Lamb, the symbol of Israel’s redemption at the first Passover. Christ’s whole life expresses his mission: “to serve, and to give his life as a ransom for many.”
