Would a correct summary be, The Catholic Church did not live up to my expectations?
Church didn't live up to mine, either, even as a child. So what. I didn't live up to my expectations, either. The true (or early) definition of 'perfect' is whole/complete. That's what we all want to be--whole and complete. No person, no agency is whole and complete. When God was creating the world, He did not murmur, "perfect" or "whole and complete". He said it was good. So while you and I--and the Church--are not perfectly whole and complete, parts of us are good. I'm not completely good--a lot of parts of me are missing. Same with the Church. And we work from there. I don't know about you, but I'm not satisfied with just being a decent person.
Did you see yourself and others as being decent in Church, but not outside of Church? I'm the opposite. Before I go to Church, my prayer is, God let me be as decent inside of Church as I am outside of Church. I may be living it backwards, but I need both places to work on being whole and complete.
