Behold the Lamb

"But the Lord's messenger called to him from heaven, 'Abraham, Abraham!' 'Yes, Lord,' he answered. 'Do not lay your hand on the boy,' said the messenger. 'Do not do the least thing to him. I know now how devoted you are to God, since you did not withhold from me your own beloved son." As Abraham looked about, he spied a ram caught by its horns in the thicket. So he went and took the ram and offered it up as a holocaust in place of his son." (Genesis 22: 9 – 13)

Isaac said to the Abraham, his father: We have the priest, the altar and everything for the sacrifice. But where is the lamb? Abraham answered him: God will provide the lamb at the appropriate time.

When John the Baptizer saw Jesus, he said to the crowd: Behold the Lamb of God, who is the true sacrifice for our sin.

The Church teaches that Jesus is not only the Lamb for the sacrifice, he is also the priest and the altar.
