Oh, come on guys, it's totally a joke. Auron and Seymour Guado being high ranking members? Seriously. They're crossing over into Final Fantasy, too. And did you take a look at the picture of their 'New York temple'? It's got a cross on the top. Actually, just looking for it quickly, that's actually a neoclassical church called the Pantheon in Paris. So...
It's just a bit of humour, nothing more. Done with apparent dead-seriousness, but meant to be humour all the same.
