“Then Peter took him, and began to rebuke him, saying, Be it far from thee, Lord: this shall not be unto thee.”
Matthew 16:22 — Greek Interlinear
Church Fathers on Matthew 16:22
While Christ was yet speaking the beginnings of the things which He was shewing unto them, Peter considered them unworthy of the Son of the living God. And forgetting that the Son of the living God does nothing, and acts in no way worthy of blame, he began to rebuke Him; and this is what is said, 'And Peter took him, and began to rebuke him.'
We have often said that Peter had too hot a zeal, and a very great affection towards the Lord the Saviour. Therefore after that his confession, and the reward of which he had heard from the Saviour, he would not have that his confession destroyed, and thought it impossible that the Son of God could be put to death, but takes Him to him affectionately, or takes Him aside that he may not seem to be rebuking his Master in the presence of his fellow disciples, and begins to chide…
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.
