Christianity is not a code for living or a philosophy of religion; rather, it is rooted in real events of history. The reason it’s scandalous is because it ties up the truth of Christianity with the truth of those historical facts. This means that if these historical events are shown to be fraudulent or fictional, then the whole basis of Christianity is removed. To put it as simply as possible: the truth or falsity of Christianity stands or falls with individual events within history.   —William Lane Craig (from, The Challenge of History)
