Empricial findings in neuroscience or any other discipline don't change whether or not the structure of some argument presumes its conclusion. Neuroscience (which, by the way, brings materialism in as an assumption) or not, it's still question begging to draw on materialist assumptions to argue against Christianity. If you want to claim that drawing on Christianity to argue against materialism is also question begging, you'd be right, but that doesn't change the fact that the former is question begging also.
