The importance of detailed deities

I was hoping to get some input and opinions.

It seems like the majority of fantasy novels have a really detailed breakdown of "Gods." How important is this to you, as the reader?

The only reason I bring this up is because, in my recently finished manuscript, I allude to higher power(s) in the verbage that my characters use ( "By the Gods", "Gods, that hurt", etc.)

However, aside from showing that there is some form of organized theology, Gods play no part in my story. Is this a mistake? Should I give more detail, or perhaps take it out completely?

As always, all thoughts and input are greatly appreciated.

 

I appreciate the feed back...Yeah, like I said, outside of using them as a expletive, the gods play no role whatsoever. The only reason I got to thinking about it is because I'm currently reading "The Name of the Wind". Rothfuss uses so much theology that I started wondering if maybe I had made a mistake by not using more detail...But at the end of the day, you guys have helped to confirm what I already know. Thank you.

 

That's all I needed to hear, guys; thank you. No matter how great you think a story is, sometimes you just need a bit of affirmation.

 

See, that's the thing, though: I have no theology in my story, no hint of religion beyond the words "Dear Gods"...I was just second guessing myself, wondering if, since I mentioned them, I was obligated to create some sort of back story or history.
