I doubt he would say that his work is primarily apologetic. I think he would claim he is first a philosopher. He has absolutely offered apologetics.
Here is an anti-Aquinas argument that I think dismantles much of Catholic thought on the nature of God. It is mostly my translation of Ostler. It is probably more complex than an argument that would pull anyone from one religion to another, but it is a problem I have with Catholic thought.
1. It is easy to say, “the Bible says, ‘call no man father,’” Catholics call men “father;” therefore, Catholicism contradicts the Bible while claiming to embrace the Bible.
*2. How about this, Catholics believe that God the Father is non-begotten and non-proceeding, God the Son is non-proceeding but begotten, and God the Spirit proceeds from the Father and the Son. How is it possible that these three are co-equal? Or co-eternal? *
3. How is it true that God is impassible and unchanging and yet He love us individually.
Or
3a. How can we freely choose between two available options and God know (before or after our choice it does not matter) what we did choose and yet He is impassible.
Now, one is stupid. I have defended Catholicism from such idiocy myself. (But I think LDS are attacked similarly here at Catholic Answers).
Two is more complex, but I am not convinced there is no way out of it.
3a is very philosophy heavy, but I believe Aquinas struggled with this and didn’t solve it.
Let me state it somewhat differently.
- All that God is and knows is uncaused. God is what He is independent of anything that is not-God. He possesses Aseity. Or he exists absolutely “a se” of Himself. Nothing predicated of God may be said to be caused by anything that is not-God.
- Humans possess genuine freedom. What this means exactly is debated, but Aquinas and Augustine seemed married to the idea that we act by choosing what we think we should such that our actions are caused by our will. We act in a way that is the result of our choice.
- God knows all things. While philosophers have debated what “all things” are, nobody would suggest that God does not know what I choose to do yesterday. God knows what I did yesterday.
- It is impossible for what I did yesterday to be independently caused by me such that I was free act as I saw fit and for God to know what I choose to do yesterday without some component of His knowledge being caused by my choice.
So if I cause my acts FREELY, God cannot know what I FREELY caused and still not be affected by me.
While it may seem trivial to the casual observer how God could know what I did yesterday, it is not if God possesses Aseity. One might say, surely God can “watch” me make a choice (some might even talk about watching from “eternal time,”) but to observe me do something is to be affected by me and God is not.
The reason I link it with #3 is that this is a big deal for me. If God is unchanged, immutable, and impassible; I cannot believe He loves me. Believing God loves me is IMO necessary for having a proper relationship with God. Therefore I reject the idea that God is immutable, impassible, absolutely unchanging, and exists a se. The God I know loves me as an individual and is affected by me. He hears my prayers because I choose to offer them. He feels my love because I express it to Him. He has an I-Thou relationship with me, not an I-It relationship with me.

Which only reflects a lack of understanding of Catholic belief and thought. God loves you, whether you believe it or not. Even if you believe God needs to be like a man to love, doesn’t make it so. As has already been stated, straw arguments. This one being “God can’t love me.” Such is what Mormonism does to the mind. There are underlying assumptions in Aquinas and all Catholic teaching, the first is God is love and created us for the only reason that He loves us.
This is the awe inspiring nature of God. He doesn’t need to love you, he doesn’t need anything. You are loved unconditionally because God is love. To argue otherwise is to these Catholic ears, the whispering of another, as who would want you to believe that God does not love?? And then create arguments for this belief??
Also seriously reflects no understanding of God, who is the creator of all things, including time. Lack of understanding transcendence.
In other words, the usual overlaying of Mormon belief and understanding rather than seeking to understand.
The only things Ostler is demolishing are souls.
