I don't think anything particularly unique about Catholicism. I think it has more to do with losing the faith due to peer issues as a teen and then regaining the faith as an adult.
And, I think, in this case, one could easily replace Catholic with Orthodox or with one of the various Protestant sects easily enough. That is not always the case with posts from this site.

Ah! My prep school religious experience was, if anything, quite the opposite. My apostasy came later, in grad school and a bit after. Marriage and the arrival of the boys reversed that aberration.
