No female is ordained under the Catholic beliefs because Jesus had no female disciples. (At least that's what they said) lol...
Nuns are proclaimed and "married" in body and soul to God... from then on they will serve for the Purpose of God and for his well-being.
well, I have no problems with the Nuns they have served and made their existence a meaningful one. But I hate the "male" ones lol... they cling to the title "Priest" as if it were some higher position when in fact they all serve the same God and is bound by it. And most of the Catholic scandals are committed by Priest.
IMHO
