You betray your own ignorance and prejudice by insisting the Catholic Church identifies itself as such "somewhat ambiguously."  There is nothing "ambiguous" about it, although your use of the word leads me to belief you don't know the meaning.  Let me make this clear:  the Catholic Chuch unequivocally refers to itself as the "Catholic Church."  Only bigoted and moronic Protestants generally insist on insisting we Catholics call ourselves "Roman" Catholics.  The truth and reality is that we have the right to call ourselves whatever we choose, not what YOU choose.  Dude, better look in the mirror and ask yourself your true motives and re-editing and calling us "Roman" Catholic.  You appear to be a nitwit, but i don't insist on your identifying yourself as one.  By the bye, for us Catholics Protestants are "apostates":  get out your dictionary and grow up, pal.
