First thought: she would love to believe they're simply good but incompetent, but more probably they don't actually care enough to do anything more than look sad and make speeches. Still, she'll take it, that's still extraordinarily good by the standards of horrifying heathen cultists.
Second thought: ...creating unlimited water like that - that only persists if drunk, what, seriously, why - does not in fact sound like something a cleric could do. ...Is Griffie, possibly, from a Far Realm in which there are entirely different gods and entirely different magic.
"I see. The true Church is a single body - made up of all of the faithful, but organised by the hierarchy of priests and acolytes and spread all across the known world as far as it can reach." And, hopefully, beyond. "It is... admittedly a lot of work. I can well understand those cults not bothering with it."
...On the other hand. That sounds like a fairly sophisticated - if wrong - notion of the nature of gods and how They affect the world. The clues that something is very strange here are mounting rapidly. ...Also, killing an evil god is not something she's ever known heathens to consider, for some insane reason, it's one of the most obviously reasonable and sane doctrines.
