"For the sake of argument, let’s imagine that Christianity is not the product of any one culture but is actually the transcultural truth of God. If that were the case we would expect that it would contradict and offend every human culture at some point, because human cultures are ever-changing and imperfect. If Christianity were the truth it would have to be offending and correcting your thinking at some place."
