This should be an interesting thread.
I suspect it won't be any more or different than the "answering protestants" posts.
It DOES make me wonder, if Roman Catholics are SO sure they are in the one, true church and only they are right, why they need to so often post threads like this that bash other Christians and provoke discord? It's like they have to reassure each other as often as they can especially when their view gets creamed in a earlier thread.
