Then Peter took him, and began to rebuke him, saying, Be it far from you, Lord: this shall not be unto you.

Theophylact of Ochrid
AD 1107
Peter rightly confessed what had been revealed; in what had not been revealed, he erred: that we may learn that Peter did not utter that great truth without God’s help. Not wanting Christ to suffer, and being ignorant of the mystery of the Resurrection, Peter said, "Be it far from Thee, Lord, this shall not be unto Thee."
