Leave aside the abuse scandals. Leave aside justification by faithfulness alone. Let’s just take the Trinity.
So Fatherhood is ultimate, and Fatherhood is ad intra. The Fatherhood of the Father did not come into existence after the decision to create the world. It is not in any way dependent upon the decision to create the world. And so there should be no more difficulty in saying that the Son is eternally obedient than there is in saying that He is eternally begotten. His existence is obedience — eternal obedience, obedience that could not be otherwise. The Father’s existence is authority.
Here is some basic Patristic theology: anything that is ad intra applies to the being of God. Wilson is saying that Fatherhood applies to the being of God. Since the Son isn’t the Father, then that excludes the Son. This is why you don’t project human analogies onto the Trinity.
Besides being a complete break with Nicene Christianity, it is also a break from Reformed teaching.
Subordination: talk of Christ’s subordination referred to his mediatorial kingdom, when he handed it over to the Father (115).
