It's one variation of God Wins law.

The secular version, Godwin's law, states that "As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches one."
This can be further derived into God Wins -law, which replaces Hitler and Nazis with God/Jesus/Allah/Mohammed argument (with either similar or opposite intent as the Hitler analogy), and proceeds to state that at this point, God Wins the thread and makes it unusable for further use in much the similar way Hitler and his Nazis do.. It is notable that this does not prove or disprove God's existence or nonexistence - fictional characters are just as capable of ruining threads. For example, substituting Hitler with Emperor Palpatine tends to have the same effect...
