Orthodoxy is my doxy and heterodoxy is your doxy.

Some people may think that it is a dangerous attitude to take toward the Bible, to pick and choose what you want to accept and throw everything else out. My view is that everyone already picks and chooses what they want to accept in the Bible...I have a young friend who whose evangelical parents were upset because she wanted to get a tattoo, since the Bible, after all, condemns tattoos. In the same book, Leviticus, the Bible also condemns wearing clothing made of two different kinds of fabric and eating pork...Why insist on the biblical teaching about tattoos but not about dress shirts, pork chops, and stoning?

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 of this, and yet when they enter church ministry they appear to put it back on the shelf. For reasons I will explore in the conclusion, pastors are, as a rule, reluctant to teach what they learned about the Bible in seminary.

In the ancient world, Christianity was even more diverse than it was today.

And above all, you must be asking which door is the true one; not which pleases you best by its paint and panelling…the question should never be: ‘Do I like that kind of service?’ but ‘Are these doctrines true: Is holiness there? Does my conscience move me towards this? Is my reluctance to move to this door due to my pride, or my mere taste, or my personal dislike for this particular door-keeper?

The search for truth takes you where the evidence leads you, even if, at first, you don't want to go there.
