The best reason for the serious study of history is that virtually everyone uses the past in everyday discourse. But the historical record on which they draw is abundantly littered with myths, half-truths, and folk history; historians can, or should, provide a corrective for this. This remark applies particularly to the history of Christianity and of the Christian church, which represents a familiar component of popular knowledge, part of “what everybody knows.”
