Not every priest is living such a lie, though media reports make it easy to believe otherwise. We don't focus on them because it's impossible to really know who they are. Instead, we focus on the significance of broken vows, as if it proves anything other than not everyone is worthy of the priesthood. Yes, priests will fail to keep their vow of celibacy, but, in the call for devotion and sacrifice, that may not really matter.
What matters are the unnoticed many who will succeed.
