[.. and you DO realise that there is a difference between ancient Romans like Mark Antony, Caligula, Marcus Aurelius, Septimus Severus and between Catholicism, don't you? ..]

Sure.. There was no Roman Catholicism until Constantine forced all those pagans to become christians.. if that was possible.. which is wasn't.. After that instantly "priests" were needed to assuage the pagans.. pagans needed priests.. Thats where the term "priest" became a psuedo christian word.. And Roman Catholism became a Cult.. as it is today..

Your history is wrong again. Constantine didn't force anyone to become Christian. He just no longer made it illegal to be Christian. No pagans were forcibly converted to Christianity under Constantine. And "priests" or "elders" were part of the Church from the earliest days, taking the traditions of Judaism.
