Literally "belief lover".
As for the previous poster, you fool that's not what credophile means. Credophile is an awesome term coined originally by the writer L. Sprague de Camp, in a letter to James Randi.
It's a label for those who appear particularly
gullible and are particularly inclined to believe
whatever claims come their way. (See Scientologist).
To quote de Camp directly,
A credophile gets positive
pleasure from belief and pain from doubt... The credophile collects beliefs the way a jackdaw does nest ornaments: not for utility but for
glitter. And, once having embraced a belief, it takes
something more than mere disproof to make him let go.
