It seems like the Religious Studies move largely eclipses the Righteous Fury move.  The former allows you to ask "What god does it serve?"/"What god is revered here?" while the latter allows "Does it serve that deity?"/"Is that deity revered here?".

While I can imagine circumstances where RS might not totally replace RF (if there are multiple gods revered at a given place, perhaps?), they seem awfully narrow.  I think RF probably needs something else to properly differentiate it.
