I simply acknowledge that's how everyone for over a thousand years believed. Aquinas isn't unique in that regard. And whether he is saved or not is irrelevant to the fact that White is rejecting the standard Christian view of divine simplicity.
His views are fairly standard from Augustine until Luther, and I have outlined them
here. When he would read the word
iustificare, he would see it as "make righteous." In Latin that is literally what it means. He could then turn the tables on us and ask how we reject the clear meaning of the word. We would respond with arguments from the Greek, but that's a moot point since view had access to Greek until Constantinople fell.
It's pretty easy to verify. Are Owen and White and them interacting with Muller, Steinmetz, Trueman, and Oberman on these issues? The answer is clear. They aren't. White deliberately punted on that when he brought up my name.
