Well, of course, coming from that tradition, once doubt creeps in, the ediface crumbles. He writes,for example,
While science has yet to answer every question about our existence and our place in the universe, it has gone a remarkable way toward that end. I expect there will always be mysteries waiting to be investigated, but the scientific method has served us well. Coming as I have from a Christian tradition that flatly refuses to acknowledge the discoveries of science, my faith has limited my understanding of the world and my pursuit of truth. I cannot live in this way any longer. I feel much more confident leaving questions of our physical world and the cosmos to science. I understand that some Christians can reconcile their faith with the scientific account of our origins, but I see no reason for this approach at this time.I've argued before that I think the rigidity of the Evangelical tradition is its weakness for just this reason.
Notice how he refers with some disdain to "some Christians"... meaning mainline Protestants and Roman Catholics, who do not deny science.
