God is a Trinity. God, as presented in the Bible, is one God who exists as three persons. As great of a mystery as this is, it is the only conception of God that A) solves the one and many problem of philosophy and B) avoids the self-defeating contradiction inherent in all views of a unitarian God.
If this is "sophisticated theology", I can imagine the prominent counter-apologists dismissing it as irrelevant gobbledygook.
Case in point, an attribute is defined as a characteristic of God intrinsic to His nature, to where it is impossible for God to be God, and yet not have that characteristic. Thus, an attribute of God is “personality” as I have already said. Personality requires relational existence. Therefore, if God were not a Trinity, who then did God have a personal relationship with prior to creation? He would not be a person until He made other persons, which would make Him dependent upon creation, thereby removing His distinction from it and His sovereignty, thus causing the whole concept of God to drown in contradiction. If God did not have the attribute of personality until the start of creation, then He existed without a characteristic that is necessary to Him by definition. I think you get the point. The triune God solves this problem since for all eternity the one God had a personal relationship among the three persons of the Trinity.
You'll notice in that second paragraph that it relies on bare assertion and argument from ignorance - no evidence or sound argument is provided.
A friend once commented that, in general, philosophy is a black hole. If this style of gobbledygook is what a philosopher has to do when they don't have evidence or a straightforward explanation, then I can see why so many laypeople think philosophy is crap.
