“Get behind me, Satan! You are a hindrance to me” (Matthew 16:23, ESV)
Peter is the only disciple who was called “Satan” by Jesus. It was the strongest rebuke ever uttered by the Lord to any of the twelve – Judas included.
Moments after Peter was commended for his confession of Jesus as the Christ of God, he was being rebuked for insisting that Jesus need not die in Jerusalem. It was an echo of the temptations Jesus endured from Satan himself (Matthew 4:1-4).
Like Peter, Satan knew Jesus was the Son of God. Like Satan, Peter encouraged Jesus to avoid the cross. Peter had become “Satan’s catspaw” (Robertson).
