But he turned, and said unto Peter,
Get you behind me, Satan: you are an offense unto me: for you consider not the things that be of God, but those that be of men.

Go after me, Satan. The words may signify, begone from me; but out of respect due to the expositions of the ancient fathers, who would have these words to signify come after me, or follow me, I have put, with the Rheims translation, go after me. Satan is the same as an adversary: (Witham) and is here applied to Peter, because he opposed, out of mistaken zeal, Christ's passion, without which the great work of man's redemption could not be effected. Peter, however, unknowingly or innocently, raised an opposition against the will of God, against the glory of Jesus, against the redemption of mankind, and against the destruction of the devil's kingdom. He did not understand that there was nothing more glorious than to make of one's life a sacrifice to God. (Bible de Vence)
Thou dost not, i.e. thy judgment in this particular is not conformable with that of God. Hence our separated brethren conclude that Christ did not, in calling him the rock in the preceding verses, appoint him the solid and permanent foundation of his Church. This conclusion, however, is not true, because, as St. Augustine and theologians affirm, Peter could fall into error in points regarding morals and facts, though not in defining or deciding on points of faith. Moreover, St. Peter was not, as St. Jerome says, appointed the pillar of the Church till after Christ's resurrection. (Tirinus)
And it was not till the night before Christ suffered that he said to Peter: Behold, Satan hath desired to have thee; but I have prayed for thee, that "thy faith fail not "and thou being once converted confirm thy brethren. (Luke xxii. 31.) (Haydock)
