Dr. Brian Lee has an editorial in today's Daily Caller that is well worth reading.
Dr. Lee writes, "To date, all U.S. presidents have labeled themselves Christians of some sort, and it is speculative and uncharitable to question their claims or sincerity. Nevertheless, a number of presidents have provided abundant evidence in their writings or behavior that their faith was heterodox, at best. At worst, we may have serious reason to doubt whether they confessed anything at all like the historic Christian faith."
