Rebuttal against what?
Thanks to God, I'm not a "reformed" Calvinist.
But you are a Roman Catholic. Whether or not you want to thank God for that one is up to you.
Nope, you're a Roman Catholic. In the common vernacular, a Roman Catholic is a Catholic who follows the Pope, rather than a Eastern Catholic who follows the Patriarch.
The term "Roman" modifies Catholic to indicate one who follows the Pope who sits in the Vatican inside Rome.
You want to play little word games to deflect from the facts you cannot address...
