More often by married men in the family, or by single men in the family?
You may be right. But the statistician in me has to note that there are fundamental differences between teachers and priests which make it less meaningful to compare. So it may not be a statistically valid comparison.
For example, to even enter the seminary, one has to go through quite a screening process. My son is nearly through it and will likely enter the seminary this fall, so I’ve seen this first hand. He had to fill out extensive questionnaires on his family life during his upbringing. He had to write about various categories of problems he had, academic, social, medical, emotional, and some others. He had to describe his relationship with other kids and his teachers, and specifically identify any types of problems he had. He had to write a detailed autobiography about himself, with many few personal details. He won’t even show me the one he turned in, and we have a very honest an open relationship far beyond most anyone I know. I know for example, that he had to write candidly about what impact my having had severe psychosis has had on him. I get the impression he might have written things he thinks would hurt me. (I still wish he’d show it to me though because I like to know the truth as he sees it.

)
There may have been other things he was required to do. I only see him a couple times a week at most so I only saw a part of the process.
And that was just the application process. Then comes the evaluation.
I don’t know what all the evaluation entails, but next month, two priests come to our house (where Matt grew up, not where he lives now) to meet with his parents and siblings. All of this is before they even decide whether he’s going to be accepted.
He cannot pay for the seminary even if he wants to, because they don’t want anybody to feel they are “owed” anything. So they are very picky about whom they invite because it is all subsidized. And if they drop out, they will not owe anything because if they do, then they might stay even if they don’t think they belong, and to avoid them covering up a problem because they are afraid if they quit they will have to pay it back. Plus I suppose if the Church decides he should not continue, it avoids any conflict of interest, in that the authorities do not have to deal with whether their decisions will place a financial burden on him.
Of course, there are all the usual background checks, including VIRTUS-required checks.
With all of these protections in place, I would hope that the clergy has fewer molesters than teachers, who do not undergo this rigorous process to get their jobs.
