For most of church history, Christians have confessed the doctrine of divine simplicity—the teaching that God is not composed of parts. But what does this mean, and why does it matter? In this episode, Anthony Alberino explores the profound connection between God’s simplicity and His unity.
We’ll see why the classical tradition insists that God is not only without physical parts but also without metaphysical or even logical parts. Unlike creatures—composites of act and potency, essence and existence—God is utterly uncomposed. Because composed beings are dependent beings, only a God who is absolutely simple can be the uncaused, necessary, and independent source of all reality.
From here, Anthony shows how divine simplicity grounds divine unity:
- Simplicity means that God not composed of parts and that all that is in God is God. His attributes are not distinct “parts” but are identical with His essence—and thus with each other.
- Unity follows because an absolutely simple being cannot, even in principle, be divided. God is not one member of a class called “deity,” but the one and only subsistent Being itself.
Along the way, we’ll consider why the attributes of God—wisdom, love, justice, power—are distinct in our minds but perfectly identical in God’s essence, using the analogy of white light refracted through a prism. We’ll also see how divine simplicity marks the sharp metaphysical divide between Creator and creature, and why this doctrine has been central to Christian theology throughout the centuries.
Finally, we touch on the connection between divine simplicity and the doctrine of the Trinity, and why classical theology maintains that distinction within God does not imply composition.
If you’re seeking to understand why divine simplicity has been called “the bedrock of classical theism,” this episode is for you.
