Kind of. In Spira, the Fayth is something that embodies all the temples, Yevon teaches us that the Fayth is all that can save us from Sin, which isn't just our sins, but an actual entity that tears through the world and destroys places. Summoners are able to harness the Fayth to battle Sin. Apparently, Sin was born from our reliance on machina, which is what the Al Bhed create.
I have this feeling that I really want to be on an airship. Like, not a plane, but something bigger.
