I don’t know if O’Reilly is Catholic. Yes, civil unions are against the teaching of the Catholic Church, but considering the new Pope supported civil unions, I doubt he or anyone else will be barred.
O’Reilly claims to be Catholic and the new Pope didn’t support Civil Unions. That was a story floated by the liberal press.
