A few more details, if they're not obvious from the race paper.
The "excerpt" was written by an elvish scholar. Elves, as they are in the Eastern Realm, are ancient, dying, bigots. They stubbornly hold onto the past and refuse to admit that they don't own the entirety of the continent anymore, just letting it go as "letting them use our land."
They're not really aggressive about it, though, just complaining and making snide, "superior" comments. It's only half-elves that they're actively aggressive towards - they view them as horrible freaks of nature that have no place in the natural way of things. They don't like dwarves much, either, because the short people tend to challenge the fact that they're the first ones there... and because the dwarves refuse to shut up about drow.
As far as religions go, in sweeping terms...
Humans have a loose pantheon. The elves are agnostics, to a point, and the dwarves are monotheistic (not only for their deities, but others, as well - they maintain that human gods are merely facets of theirs.) Halflings tend to worship human gods, and gnomes are fey, so if anything, pay homage to Oberon and Titania. (Or the Queen of Air and Darkness.) Other races have their own deities, but nothing really noteworthy. Last note - there are evil gods, and then there are evil
divinities. Other things hold divine power than the gods - demon lords, for instance. Like Orcus, and Demogorgon.
