Religions in Space!

[neotoma]

Apropos of conversations with friends this week, which SF novels deal with modern human religions in future/space-faring settings? I'm mean seriously deal with religions, as in they are integral to the setting and at least some characters motiviations and identity.

The example that comes to my mind is Sarah Zettel's Fool's War, where one of the main characters is identity as a Muslim is as important as her identity as a merchant spaceship captain.

Rec me others?

Edited for clarity: I'm interested in stories dealing modern day religions in current or lightly extrapolated forms, and really want recs for non-mainstream-Protestant religions and characters. Stories about Orthodox Christians IN SPACE, Mormons IN SPACE, Wiccans IN SPACE, Sikhs IN SPACE, Buddhists IN SPACE, etc etc.

If you want old-fashioned space opera with religious elements, Christopher Stasheff's Warlock books (and especially the prequels, like Escape Velocity and St. Vidicon to the Rescue) deal with Catholicism a lot.

And the Humanx Commonwealth books by Alan Dean Foster have a United Church, extrapolated as what might happen to the more adaptable schools of human religion if confronted with a friendly alien species which also had adaptable schools of religion. It's a major presence, not so much as a faith but as a powerful institution, sort of what would happen if the Unitarian Universalists became a major world/galactic power and the dominant religion; several important minor characters are clerics.

I wish I could come up with more but I've looked before and it's relatively hard to find any, especially non-Christian.
