God as a non-empirical being

[robvalue]

That's right. If they are saying they can differentiate between "God" acting on the world, and a natural process or a different supernatural causation, then they are saying that God has some empirical attributes after all. Otherwise, they are simply making an argument from ignorance or incredulity fallacy. So they undermine their entire position when they say God cannot be tested or measured.

They are hiding God so that he becomes unfalsifiable. All unfalsifiable claims are useless because their truth can never be determined. If they do have some knowledge about an unknowable being, they have contradicted themself.

This is religion's bread and butter: unfalsifiable claims. As soon as they step outside of that fallacious circle of misguided smugness, reality smacks them down. Religion has never made a single testable claim that has been proved correct. For example, prayer fails like a motherfucker if you put it under scientific conditions. It only "works" when people are free to interpret the results however they want and confirmation bias takes care of the rest.
