On the trip to Antioch, we saw St. Peter's Church, which is high in the mountains above Antioch. In this cave church (which once had a mosaic tile floor and murals on the wall), St. Peter and others met and worshiped as Christians. Anyone coming to this church is granted a plenary indulgence for all sins. In other words, if you make pilgrimage to this church, you are forgiven all your sins.
In the middle ages, people would make a pilgrimage to this church, buy a St. Peter's medal, and pray for forgiveness. In the middle ages, a pilgrimage to St. Peter's would be incredibly dangerous -- over the stormy seas, through treacherous mountains, through strange cities, and past bandits and robbers. Anyone surviving the pilgrimage and returning home would be famous!
