I actually happen to
love the term “Roman” Catholic because of my particular fondness for ancient Rome. Infact, understanding the Roman Republic helps tremendously in understanding not only why the Catholic Church is the way it is, but also why such a deep rift exists between Orthodox and Latin-rite operations.
A thorough explanation would be too long, but basically the Romans were
very traditionally minded individuals. The Romans were very conservative and when changes were proposed, they would have to be viewed in the light of what the Roman Fathers did. This is the difference between Julius Caesar and Octavius. While both were emperors, Julius Caesar was killed because he blatantly went against the tradition of the Roman Republic, while Augustus manipulated the Repulican system to, in effect, make him emperor while presenting the appearance of carrying on the traditions of the ancients. Julius was killed, Augustus was hailed.
Furthermore, the Romans were very legalistic and if you observe the practices of the Latin-rite Church and the Eastern Orthodox, this difference becomes apparent in how worship and theology is approached.
In either event, as I am a
big fan of ancient Rome, I am proud to call myself a
Roman Catholic
