With all due respect, it seems to have been less than universally effective at that for Protestants. And I say that having been one up until last month.
Well once the clergy's wives figure it out, they probably aren't able to keep it a secret for long. My point was the boy-raping "priests" were able to hide their queerness under the cloak of celibacy...none of them are married.
I think we can figure out pretty quickly who the Protestant fake clergy are. The problem is the wish-washy sects that allows them to continue serving in the church....especially with boys around.
