My thesis can be stated simply: scribes occasionally altered the words of their sacred texts to make them more patently orthodox and to prevent their… - Bart D. Ehrman

Historians can establish only what probably happened in the past, but miracles, by their very nature, are always the least probable explanation for what happened. This is true whether you are a believer or not. [...] If historians can only establish what probably happened, and miracles by their definition are the least probable occurrences, then more or less by definition, historians cannot establish that miracles have ever probably happened.

Miracles, by our very definition of the term, are virtually impossible events. [...] We would call a miracle an event that violates the way nature always, or almost always, works so as to make the event virtually, if not actually, impossible. The chances of a miracle occurring are infinitesimal. If that were not the case it would not be a miracle, just something weird that happened. And weird things happen all the time.

One of the most amazing and perplexing features of mainstream Christianity is that seminarians who learn the historical-critical method in their Bible classes appear to forget all about it when it comes time for them to be pastors. They are taught critical approaches to Scripture, they learn about the discrepancies and contradictions, they discover all sorts of historical errors and mistakes, they come to realize that it is difficult to know whether Moses existed or what Jesus actually said and did, they find that there are other books that were at one time considered canonical but that ultimately did not become part of Scripture (for example, other Gospels and Apocalypses), they come to recognize that a good number of the books of the Bible are pseudonymous (for example, written in the name of an apostle by someone else), that in fact we don't have the original copies of any of the biblical books but only copies made centuries later, all of which have been altered. They learn all this, and yet when they enter church ministry they appear to put it back on the shelf.
