"Un rabin vorbește cu papa despre Dumnezeu."

Translation: A rabbi speaks with the Pope about God.

[sage-tea]

I've heard "preot" more often than "papa".

[fifilaplume]

"papa" is the Pope
"preot" is "priest"

[Mdlina170278]

Papa sau papă este la catolici, noi avem preot

[Ursu_Brun]

I think you mean "popă", not "papă". Popă is indeed the colloquial noun for priest, used by almost everyone on the street, while preot is the literary word.
