I'm fairly sure that in vanilla FFH Order changes your alignment to Good. And, since FFH/Keal is still the first authority concerning Rife lore, this makes Order a "Good" religion (lorewise).
I have always felt that the term "Good" in FFh (and to a lesser extent in Rife) doesn't actually mean that a leader or a religion is "good" but rather that they are likely to stand on the side of the "Good" gods in their war against Agares etc.
Bannor are one example for that but it becomes even more obvious if you take the time to actually think about the Alignment of the Grigori and especially Cassiel.
Cassiel is true neutral, the most neutral of all FFH leaders in fact, yet he has an almost Gandhi-like character (except that he realizes that peaceful resistance won't get you very far in Erebus). and that isn't "good" then I don't know either.
