That is actually a very insensitive statement... but you probably don't realize that so I'm going to let it pass. But do keep in mind, there are still practitioners of non-judeo-christian religions. Like... Druids and Wiccans, even worshipers of Odin who might take offense to that statement above. So you're handling someone's religion here, of course people are going to get touchy.
I think the main concern people have here is that you're going to shit all over someone's religion in the name of fiction, which is a legitimate concern. (i know this is contrary to my who cares he's writing fiction statement, but admittedly I was a few glasses into the evening, and oh the flippant shit I say when tipsy.)
I would suggest picking up some of the viking sagas or early Irish and Welsh texts. You can get translations of a few of them on Amazon for free. And visit your local library.If you think about the most successful author of what I call super fantasy (elves, orcs, goblins etc.) it's Tolkien and the guy was a medievalist who borrowed heavily from Viking sagas (There is literally a saga about a guy named Frodi who has to destroy a ring),
Also, I think it might be more impactful if you just have one set of gods you focus on and write a story about infighting among them. It would also mean less research for you, (compelling fantasy is research).
