Telic 21

I am hoping that someone will be able to help define Natural Theism. I understand it to be a term that was first used by Henry Nelson Wieman, a Unitarian. From the little that I know, it resembles an early form of Deism. Is anyone familiar with it? Is it a belief system that uses the Bible at all? Are there Christians that use the term? Does anybody know of any resources? Websites? Books? Thanks.
