What Is Divine Simplicity?

Divine simplicity is one of the most ancient confessions of Christian theology, taught by the church from its earliest centuries. It means that God is not composed of distinct, separable parts. He is not a being made up of love plus justice plus power plus knowledge as if these were ingredients combined. Rather, God is His attributes. He does not have love; He is love (1 John 4:8). He does not have life; He is life (John 14:6). He does not possess wisdom as a quality added to His essence; He is wisdom itself (1 Corinthians 1:24, 30). Deuteronomy 6:4 declares, 'Hear, O Israel: The LORD our God is one LORD.' This unity is not merely numerical (one rather than two) but ontological — God is utterly indivisible. James 1:17 says with Him there is 'no variableness, neither shadow of turning,' because there are no shifting parts within Him to vary. Why does this matter? First, simplicity protects God's perfections from being limited or in tension. His justice does not constrain His mercy; both are expressions of the one undivided God. Second, it secures His unchangeableness — a being composed of parts could lose or rearrange them, but a simple God cannot. Third, it grounds God's aseity: He is not assembled from prior realities. Fourth, it shapes our worship. We do not worship some attributes more than others; we worship the one God in whom all perfections are infinitely and equally true. Divine simplicity is also why the Trinity is not a contradiction. The three Persons are not three parts of God; each Person fully possesses the one undivided divine essence. The doctrine humbles our reasoning — God is not like anything in creation. He is uniquely, simply, and gloriously Himself.
