Jesus turned and said to Peter, "Get behind me, Satan! You are an obstacle to me. You are thinking not as God does, but as human beings do."
Gospel's Commentary
Today Jesus gives Simon Peter a very strong response. What a rebuke! Just a few seconds earlier, Peter had confessed that Jesus is the Son of God, and Christ in turn had entrusted him with the primacy of the Church—he is the first Pope! But then Jesus, speaking to them in confidence, adds that He will be put to death… Simon refuses to accept the Lord’s Passion: “This must never happen to You!”
—Peter is thinking like a mere business “manager”… and has become a slave to success. But God is God, and His logic is different: His success is “giving Himself out of love.”
