This is absolutely no excuse for ignoring child abuse but it might be part of the puzzle as to why it was allowed to occur for so long. It is thought a significant percentage of practicing clergy are closeted agnostics or atheists. Quite a number from different backgrounds have confided this and the most common reasons are that in seminary or the equivalent the depths that biblical teachings go to leaves them unbelieving because it is simply so hard to believe once you peel back the superficial layers. Another reason is that as a community leader many of them feel hopeless in helping which contradicts their reason for becoming a priest. Eventually all of the "it's all a test, keep praying" doesn't make sense any more. By all accounts it's an extremely lonely existence pretending to everyone you are someone you're not and feeling trapped into doing it day in, day out.
So, if you wonder how someone could so ironically run a sermon that speaks against the very crime going on under one's nose there's a potential explanation. They themselves may not even believe what they're saying anyway. It all adds into an existence that is secretive and protective.
So it's all the closet atheists turning a blind eye to child abuse that kept this thing going so long? I must've read that wrong, cause that's easily the dumbest thing I've read on blitz, unless I've misread it.
Did you read the part where I said "part of the puzzle"? The secretive nature of that organisation buries a lot of things.
