The successors of Peter also speak for the disciples. We follow his teaching authority, and he is for us a symbol of and foundation for our unity. One faith, one baptism, One Lord.
So a Catholic who make a pilgrimage to Rome visits the Four major basilicas, especially St Peters which is built above the Tomb of St. Peter. The Pope speaks to the people in a General Audience every Wednesday, so yesterday we gathered with some 70,000 other pilgrims to see the pope and to listen to his teaching. It is a big gathering and everyone tries to get close to the barricades so that we can get a good look at the Pope as he passes by.
We got pretty close and I got a great picture.
