Oddly enough, early in the Wasp's career with the Avengers she was shown to have the ability to sense the presence of evil. This was explained as a function of her female intuition and her insect super-senses. See: Avengers #2, page 14 (reprinted in Avengers Classics #2 (September 2007).

Atheist representation on the Avengers
The teams pretty well rounded now, but are there any atheistic members?...

In the Last Avengers Story, the Wasp said she didn't believe in God.
