Sorry, I should have elaborated. Theistic evolution takes into account the idea of souls, and doesn't cause a person to have to choose between the Bible and science. The third category is someone who is spiritual, perhaps religious, who doesn't believe in creationism, doesn't really follow any particular ancient/holy text, yet believes in ID. Fine line maybe but the difference is that the former category is made up of theists who reconcile their theology with science. In other words, a believer doesn't need to be a theist. Yea, I've heard those concepts brought up, as well. Thing is, when you believe in God, you believe that he is the creator, and that humankind is discovering his creation. For example, my belief is that God created gravity but humankind discovered the science behind it, and gave it a name. Same with all other scientific theories. When I identified as an atheist a few years back, I didn't believe any of that - rather, that the universe just ''is,'' and that science is the revealing of the mysteries of the universe. The difference between my beliefs as an atheist, and my beliefs as a believer now is that I believe that the mystery is God.
