Hilary of Poitiers
Catena Aurea · Matthäusevangelium 16
Then Peter took him, and began to rebuke him, saying, Be it far from thee, Lord: this shall not be unto thee. But he turned, and said unto Peter, Get thee behind me, Satan: thou art an offence unto me: for thou savourest not the things that be of God, but those that be of men.
The Lord, knowing the suggestion of the craft of the devil, says to Peter, Get thee behind me; that is, that he should follow the example of His passion; but to him by whom this expression was suggested, He turns and says, Satan, thou art an offence unto me. For we cannot suppose that the name of Satan, and the sin of being an offence, would be imputed to Peter after those so great declarations of blessedness and power that had been granted him.
