Dale Tuggy has two methodological tricks for deflecting Trinitarian prooftexts. He has a hermeutical trick by which he relegates all divine ascriptions to Jesus to merely agential ascriptions. And he has a philosophical trick by which he preemptively discounts all divine ascriptions to Jesus because they (allegedly) violate the law of identity.
Unfortunately for him, his two methodological tricks are working at cross-purposes.
I. The epistemic indiscernibility of identicals
If any divine property or prerogative, however apparently unique to God, can be reassigned to a creaturely agent, then there’s no way to tell the difference between what’s God and what’s not God. At a noetic level, the Creator and the creature become perceptually indiscernible.
II. The ontic indiscernibility of identicals
And the dilemma, if possible, runs even deeper. If mere creaturely agents can actually assume divine properties and divine prerogatives, then the Creator and the creature become metaphysically indiscernible.
Tuggy’s monotheism quickly degenerates into pantheism. A chain-of-being in which divinity is a matter of degree rather than kind.
