North American College, you'll see that they were heading over there at 6:40 a.m. this morning for Mass.
Of course, St. Peter's is the mother church of all Catholics. One could spend hours in St. Peter's and still not have seen everything. As I mentioned in a previous post, apostles, saints and popes are buried in almost anonymous fashion beneath altars, in niches and in the crypt. Unless you know what to look for, you can walk right by Pope Pius X or St. Simon or St. Jude and have no idea. Although, obviously, the most important spot is the side altar where the Blessed Sacrament is exposed for prayer and adoration.
