Churches are sometimes called...perishes. Perish means to expire, or in the case of humans, to die. Hmm. So here's what I think: The Romans wrote the Bible and hid all those "unknown" Bible-parts (can't remember the word, dang), like the one by the Black Sea. it's all a ginormous practical joke, sort of. But also a kind of massacre. I say on some overlooked Holy Day (like Good Friday--one that's not terribly celebrated), the churches will explode. Old ones, at least. Old bible, old testaments, old everything. Recall the whole perish thing. Anyone else understand a word I'm saying?
Nobody is going to understand what you are saying because the most basic part of your theory is wrong. There is two spellings to perish, perish, as in to die, and parish, as in a church. Good try.
