Subject for debate?

God is not subject for debate, because he is who he is and what he is. We are told that the unbeliever, of course, does not agree with that; and that is perfectly true; but that makes no difference. We believe it, and it is a part of our very case to assert it. Holding the view that we do, believing what we do about God, we cannot in any circumstances allow him to become a subject for discussion or a debate or investigation.
