Just a warning: being the equal opportunity offender he is, there are a couple of parts in these videos where it sounds like Colbert is mocking the claims of inerrancy and in addition makes some off-the-wall comments (it is Colbert after all). But nevertheless, he surprisingly makes some good (hilariously glaring) points and even pushes Ehrman a bit on his claims. Seems like maybe Ehrman is getting frustrated in portions of the videos? Not positive on that, but you’ll just have to watch and see for yourself.
