I thought he DID do it. Didn't the nun tell him that she had talked to a nun at his previous parish and had found out that he was molesting boys there, too. (We find out later that she had not, but was using this to fish out his reaction.) When she told him this he seemed to stop his denials and became much more like, "Why are you doing this to me?" She told him he must leave her school. And he didn't seem to argue with her at this point. He seemed resigned that he had been caught again.
The next thing we know, he's leaving that particular church -- and we know that he DID resign on his own, because the sister mentions that in the last scene -- but the hierarchy has moved him to a bigger church/school.
Actually, I don't think she ever comes right out and says that he was molesting boys. I *think* she says, 'I talked to a nun and she told me what you did." But never comes out right and says it, in case she doesn't get the details right, or is wrong.
When he stops and asks what he's supposed to have done and why she is doing this to him, she again is vague and says something like "You know why."
She was hoping to trap him and that HE would say what he had done.
I got the impression when he heard that a nun was spreading the tale, that once again
rumors and inuendoes of what he had done had caught up with him. How do you fight a rumor? Even the people in Hollywood have a hard time squelching an untrue rumor.
He said very succintly, "Why didn't you ask a priest? Why did you asked a nun?" Like the
nuns were spreading rumors about him. That it is hard to defend a rumor that keeps going around in such an underhanded way.
When you think about it, that's exactly what Merle's character did. She acted on
suspicions, but had no proof. And he ended up resigning under the pressure and suspicion (only) of scandal - maybe,
just as he did at the last place.
Merle's character may not have had any more proof he did anything wrong than the last nun, yet BOTH of them forced him to leave, with their suspicions. Hmmm...
