I like the name
Christian despite being a non-Christian. I don't think it would be weird for non-religious people to use it. Somehow,
Christian doesn't seem as overwhelmingly religious as many of the "hip Bible" names that are currently super hot, like
Levi or
Elijah or even
Jacob. It is very handsome, and somehow Christians avoid getting shortened to
Chris the way Christophers are. I've never met a
Christian that didn't go by Christian-in-full.
