Well it makes God-related arguments invalid, obviously.
For example, if he says "LIFE STARTS AT CONCEPTION CUZ POPE SAID SO ZOMGWTFBBQ" that argument is invalid.
Arguments Christians make are always based on the Bible, which is why they are bullshit. A pro-life argument that didn't require the Bible to make sense would still be bullshit, but it wouldn't be so obviously bullshit so people might discuss it more.
