Take this review with a grain of salt because I am reflecting from the perspective of an audience that the book was not written for. This is an academic book; I am writing from the perspective of a lay person. Consequently, I have mixed feelings about this book. On one hand, Dolezal’s scholarship on divine simplicity is extremely impressive and I am grateful for his strong defense of the doctrine. On the other hand, this book deals in so much Thomistic reasoning/philosophizing with few references to scripture. There were some references to scripture and I do think those references prove the doctrine of divine simplicity in a basic sense to be biblical, but they are alluded to rarely in this book. The vocabulary of metaphysics feels like a foreign language and for the first 50 pages I found myself using a dictionary on almost every page. So it’s not a particularly accessible discussion about divine simplicity and consequently probably not widely edifying for most people, granted it is a fairly nuanced doctrine to deal with.
So what is divine simplicity? It does not mean that God is easy to understand, but rather it means He is not made of parts. In other words He is not a composite being. There is nothing in God that exists prior to or on a more fundamental level than Himself, not even His attributes. Why is this a relevant doctrine for us? I think Dolezal puts it well when he says that divine simplicity is “necessary for a proper distinction between the being of God and the being of creatures and for understanding the absolute self-sufficiency of God’s existence.” Pause right there. Those are massively important implications of this doctrine. The self-sufficiency and distinction of God is the foundation of our unique hope in Him. It’s the foundation of His power to save us, bless us and accomplish all His purposes. It’s the foundation of His sovereignty and what makes Him God over every other person or thing. While I would say this is a fairly difficult subject to discuss, I don’t think it should be dismissed as unimportant.
Furthermore, it is important that we uphold this doctrine of simplicity so that we understand how we relate to God and how He relates to us. We should not think of His attributes as properties that compel God to act in some way as if He could be manipulated by appealing to those “parts” that determine Him. For example, we do not turn up God’s “love knob” when we are obedient or his “wrath knob” when we sin to determine His state of being. Instead, attributes help us to describe in many ways who God freely, simply and eternally is in Himself. As Dolezal puts it, “God’s attributes are not intrinsic determinations of his being, but rather they are just so many truths about the one indivisible and infinite existence and essence of God.” Certainly, He desires our prayers and appeals, but let us be keenly aware that He cannot be compelled, manipulated, or bargained with. He is who He is (Exodus 3:14). This should humble us before God and show us that He and He alone is truly unboundedly free to do “whatever He pleases.” It is in these deep thoughts that we feel the weight of what it means for Him to be Lord. On the flip side with how He relates to us, let us be assured that this also establishes His immutability meaning He cannot change. He is uncaused and has no parts by which He could be altered to be other than who He is. Everything that He has revealed about Himself and His plan for our ultimate good is just as unchanging as His being. This should give us tremendous assurance of His kindness for us now and in eternity future. It should also be a stark warning for those who do not repent and look to Jesus for justification.
These are important implications of divine simplicity that I wish Dolezal dwelled on more in this book for the edification of believers, but the church at large doesn’t seem to be the intended audience of this book. Instead, it is a far more academic discourse trying to logic-proof this doctrine in response to its skeptics. I think Dolezal actually is pretty effective in his objective but I cannot help but think that much of this musing risks some degree of vanity. I believe the biblical allusions to creation ex nihilo, the revealing that God “is who he is” in Exodus 3:14 and Paul’s exhaultation in Romans 11 that “from Him, through Him and to Him are all things” make clear that God is the source of all existence and that there cannot be anything more fundamental than who He is Himself. Thus by necessity, He is simple meaning not composed of parts. We can understand that theoretically but how do we even begin to comprehend that in any experientially conceivable way in our minds? I don’t think you can, you simply descend into a never-ending pit of jousting over definitions like lawyers. The prophet Isaiah rhetorically asks, “Who has measured the Spirit of Yahweh?” (40:13) and Paul himself declares, “How unsearchable are his judgements and how inscrutable are His ways!” It’s biblical to draw a line in the sand and say we cannot definitively comprehend any more about God than the Bible has revealed. As John Calvin says, “We must speak where the scripture speaks and we must keep silent where it is silent.” We can have thoughtful discussions about where that line is as pertains to logical implications of scripture but it is essential that we acknowledge that line exists. This is a subject that I fear causes many to lose sight of that line. Although one might argue that Dolezal pushes the envelope in this regard, he himself also acknowledges the limitation of human understanding at the end of the book.
And this incomprehensibility should not be unsettling for Christians. Atheists have the same conundrum. All people do because the human experience is one of limitation in being. How do you explain the Big Bang? One might say matter in high density and temperature. But why? Why density? Why temperature? Why matter? All you have to do is keep asking “why, why, why” in infinite and eventually you have to come to the conclusion of an uncaused cause. You must conclude that something or someone simply “is”. You can’t explain it, you can’t comprehend it, you simply know it must be true.
In spite of what comes off as heady and inaccessible discussion for the common Christian, I particularly really appreciate the “Truthmaker” framework put forth to understand how many attributes refer to a single simple essence of God. God is truthmaker in the sense that He determines what is a true description of who He is. This harmonizes the facts that words have distinct meanings and that God is a single essence. In this way we can say that God’s attributes are ontologically identical with each other in the sense that they describe the real single essence of God, but the attributes are different in the sense of what they communicate linguistically. I think this framework also fits nicely with God’s lordship and authority. Too often contemporary people bear false witness about God because they say His self-disclosure of an attribute like love must conform to an idea of that attribute they’ve created in their own head. It should be the other way around, we need to conceive of attributes like love in our heads based on how God has revealed Himself in scripture. We must learn from God rather than demand that He conform to our learning. God is who He is because He says so, not because He is trying to prove or attain those attributes in a way that is pleasing to us. This is a firm foundation for Christians who live in a world that questions the “goodness” of a Christian God. God, not man, is the truthmaker of his attribute of goodness.
There is also a very insightful discussion of divine simplicity’s compatibility with God’s knowledge and will which again I wish was presented in more laymen’s terms. Understanding this provides a powerful defense of God’s determinative foreknowledge. If one affirms that God simply foreknows things but does not determine them, they undermine the self-sufficiency of God because His being would be altered from outside of Himself. But if you affirm that God is completely self-sufficient (which implies simplicity) then you recognize that God does not know things by learning but He understands all things because He understands Himself as their cause and source. As Dolezal puts it, “God’s knowledge of creatures through his own essence as their exemplar and efficient cause yields a more perfect knowledge of them than if he just knew them by having their proper intelligible species impressed upon his mind.” Put more simply, he says, “God knows all things in knowing the full extent of his power to produce them.” In sum, “he knows all things in and of and by himself and for that reason, his knowledge is undivided, simple, unchanging and eternal.” I know we are engaging in deep reasoning here, but this is consistent with Bible’s frequent depiction of God’s knowledge as something that is active and determinative (Romans 8:29).
A final thought that I took away by implication rather than explanation in this reading is that it makes sense that God (according to His divine nature) is invisible and it is seemingly necessary for that to be the case. If God is the only uncaused cause of all things, that means His existence precedes the existence of matter and light. Again, this theoretically must be true but there’s no way to humanly comprehend this in any experientially conceivable way. Perhaps that might be an interesting apologetic point for some folks and perhaps it makes the condescension of the incarnation of Jesus Christ more apparent and beautiful. Overall, this is definitely the most difficult book I’ve read and deals with an important subject but not in a particularly accessible way that I would recommend for most people.
