Reminder, dear friend in Christ, the Catholic Church gave you the Bible. That said, let's take a closer look at Peter's reaction. No sooner is he named "prime minister", than Peter pulls the king aside and advises him to take a different road. As he had been praised by the Master, now he is rebuked. Jesus goes so far as to call him “Satan.” This illustrates well what the Catholic Church teaches about the subject. For Catholic doctrine does not proclaim that the pope can never make a mistake in personal judgment. It is only when he fully engages his authority as successor of Peter speaking from Peter’s seat of authority (“ex cathedra”) that the Church guarantees him to be acting under the charism of truth given by the Father through the Spirit.
When Peter publicly proclaimed “you are the Christ,” Jesus pointed out that this was not from him, but from the Father. When Peter privately said, “God forbid that you should suffer,” Jesus notes that the source of this was himself. And what’s worse, this human opinion was being used by a diabolic manipulator to tempt the Lord to choose comfort and honor over suffering and sacrifice.
Jesus will have none of it, of course. After all, He is the truth incarnate. And the truth is that glory comes only after sacrifice. And His own incomparable sacrifice will not make things easy for his disciples, but will blaze the trail of sacrifice that they too must walk. The sacrifice that he will offer will be Himself. The sacrifice they will be called to offer will be similar: “offer your bodies as a living sacrifice, holy and acceptable to God, your spiritual worship.” (Romans 12:1-2).
Peter couldn’t quite get it. None of them could. This is entirely understandable. During the ministry of Jesus the apostles here and there experienced a passing inspiration from the Holy Spirit, but that Creator Spirit had not yet taken up residence within them. That only came when the fire descended on them in the upper room. Before Pentecost, they ran from suffering. After Pentecost they run towards it. Peter, who denied Jesus, ultimately gave his life for him. A successor of Peter, John Paul II, preached his most eloquent sermon by continuing to serve in the twilight years of his life, a living witness of loving self-giving which is a fruit of Pentecost. cf
