Yes, that's what I would have expected from one of our midwife/nuns, they're usually putting the welfare of mother and child ahead of they're own feelings.
Maybe it's because I was raised Presbyterian and not Catholic but I never expect priests (or ministers) to be perfect or above the rest of us, they are all just men to me. Sure they are supposed to set a good example, but if they don't, we Presbyterians just fire them, we don't go into shock over it. In fact our most recent one in this town turned out to be an out of control alcoholic and after several DUI's he had to be let go, hopefully to a good rehab center. The Catholic priesthood, with all due respect to the many wonderful dedicated men in that church, does tend to attract more than it's share of bad ones probably because a "vow of celibacy" is a good way to explain why they aren't dating or marrying.
I watched this again and the priest in this episode, while clearly in the wrong, didn't seem worthy of quite so much hatred from Mother Mildred. He's not responsible for all the sins of all the priests in 2000 years of church history and to me there's a whole world of difference between a pedophile and sex between two consenting adults.
