Behind his jabs at the Christian faith (though it’s usually "young earth" creationism that raises his ire) stands a confirmed naturalist who asks how channeled revelations square with science. Unlike Christians, rationalists do not believe demons exist, so they cannot dismiss the difficulties posed by occult phenomena or The Urantia Book as manifestations of demonic power. In other words, humanists don’t have a "Satan of the gaps," as Christians do, to account supernaturally for problematic occult experiences. Their very rationalism forces them to seek natural explanations, often long after evangelicals have despaired of earthly answers and begun talking about demons.

While I certainly believe in supernatural agents, both demonic and divine, who influence people on earth, my point is that we theists sometimes give up too easily. In this case it took a hard-core skeptic to unwind methodically the tangled origins and material fallacies embodied in The Urantia Book (UB). His chronicle is a landmark exposé of the origins of the Urantian movement.
