From that time on Jesus began to explain to his disciples that he must go to Jerusalem and suffer many things at the hands of the elders, the chief priests and the teachers of the law, and that he must be killed and on the third day be raised to life.
Peter took him aside and began to rebuke him. ‘Never, Lord!’ he said. ‘This shall never happen to you!’
Jesus turned and said to Peter, ‘Get behind me, Satan! You are a stumbling-block to me; you do not have in mind the concerns of God, but merely human concerns.’ (Matt.16:21-23)
Peter loved his Lord, Jesus, his teacher, master and friend. He acted in love in trying to protect him, to stand between him and a violent fate. We know of Jesus’ love for Peter too: despite the awful triple denial Peter shouted in fear, Jesus later displayed a beautiful, tearjerking act of restoration of their friendship and confirmed his loyalty to his disciple as he evoked Peter’s loyalty to him.
However, in this case, despite Peter’s motivation and good intentions, he uttered something that Jesus did not wish to hear. Our Lord’s response was one of utter condemnation, in no uncertain terms. He loved Peter, but would not condone what he said.
Grace be with you.
