I'll just remind you all that Final Fantasy does indeed have a history of poking fun at Christianity. (Or really, Judeo-Christian and organized religions in general.) FFX being the obvious example of course. Yuna walking on water, the Church of Yevon, etc. But also, remember JENOVA? Yeah, change a letter and add another on the end and you get JEHOVAH, the personal name of the Judeo-Christian God. Then, of course, there are the obvious religious implication of Sephiroth's name (And Boss names) and the Cetra/Ancients.
