Almost any supernatural explanation can be made more complex by adding another entity. For example, there is no way to discount the theory that there is a devil pretending to be God who will ultimately put all Christians in hell and everyone else in heaven despite writing the Bible.
Many Christians will likely discount this explanation since it seems more complex. For without using this razor, how could it possibly be discounted? By this very logic, since it is possible for naturalism to explain everything written in the Bible, does that make all supernatural explanations self defeating? Does this mean that Occam’s razor is selectively used?
