Okay, this piece is biased, too — but they give references so you can check it out.
Do Christians have any obligation to use reason, to be rational about the world at large? Blatzkrieg writes about the issue here, especially with regard to vaccination phobics. (A few people in every community can safely go without vaccinations, if everyone else gets them. In too many communities, we have too many going without, for religious, political and economic reasons, and that puts us all at risk.)
It bugs the heck out of me, the “I-don’t-have-to-think;-I’m-a-Christian” view that tends to emphasize the snarkier bumper-sticker views on everything, and usually the wrong bumper-sticker. How many times today can you find someone telling you the equivalent of “I’m sure Millard Fillmore put the first plumbed bathtub in the White House, because I have faith he did — and he probably invented plumbing, too?”
