I don't think American Catholics appreciate St. Peter as much as we ought to. Maybe it's because his successors are always with us. Perhaps it's because Americans tend to dumb everything down. We either think of Peter as the first pope or we simply think of him as the head of the bumbling apostles.
Have you failed? Have you ever really messed up so horribly that a mere apology will not fix it? Go to Peter. He knows your shame and regret. He betrayed Our Lord three times after boldly saying earlier that night that he'd never do such a thing. Have you ever hidden your Faith so you could blend in with the cool folks? Peter understands. He stood around a fire warming himself with the temple servants. Have you ever been so depressed that you thought everything was hopeless? Peter's been there. From Good Friday to Easter Sunday he thought that everything was lost, that the Light of the world was gone out forever and how it must have scalded his heart when he looked at St. John and Mary.
Have you ever thought, this job is too big for me? Have you listened to your friends when they said, "What can one little person do?" Peter understands that too. He went to Rome and stayed there even though it meant losing his life. Satan and the Romans must have thought after Peter's crucifixion that the Christians were done. They were wrong. As St. Peter hung on the cross dying in agony he knew where he was going. With his help, may you and I get there too.
St. Peter, the apostle, pray for us that we may be made worthy of the promises of Christ. Amen.
