This is a point with fantasy settings that I've even taken to trying to subvert whenever I write a character or do a story involving these sorts of things. Either in the FFXIV universe or otherwise, having the religious figure not be a giant asshat seems to shock people quite often. They always jump to the priest and his congregation being behind a cult or whatever reason has them snooping around.
The XIV writers really don't seem to have much of an idea what the actual religion in the world is, if anything at all. The Ishgardian culture carries all the trappings of late medieval catholocism yet simultaneously does nothing but have a lot of influence and fancy cathedrals. Hell all I can tell you of their doctrine is 'Dragons are bad, the land will be littered with the blood of the heretics. Praise Halone!' And that's literally it, I'm not even sure they have actual services or rituals.
