Enveloped within Rome is the world's smallest country - Vatican City, officially called the Holy See. Any trip to Rome, especially if you're Catholic, would be incomplete without a visit to the home of the Pope. On Sunday morning, Aaron and I decided that we would celebrate Mass at St. Peter's cathedral. I have to say, this wasn't originally on our bucket list, but it should have been. The church itself if beautiful and it was so special to be able to attend Mass here.
