I had some bible thumping baptist going door to door tell me almost exactly that. I had time, and decided to amuse myself in engaging these two guys. I talked to them for about 20 mins before they left. I kept asking them to compare their religion to various religions around the world, including eastern relgiions, and was quoting passages from many of them. These guys clearly had never studied anything but their version of christianity. Their only defense was, “But this was written by our lord and savior, Jesus Christ”
