This paper constructively argues for a method of rooting divine simplicity in Scripture that builds on pro-Nicene approaches to the doctrine, and which has been almost entirely overlooked in the modern history of the doctrine. In the 4th and 5th centuries, pro-Nicene theologians defended the doctrine of the Trinity on the basis of divine simplicity. But for them, simplicity was also a virtue. Hence, Fulgentius of Ruspe can suggest that one needs to be simple to worship the simple God. Later scholastics commonly distinguish the moral and metaphysical senses of divine simplicity. This paper argues that this distinction is not a difference between simplicities, but two ways of considering one and the same simplicity of God, thereby giving us an evangelical path into this much-contested doctrine. Following the fathers and scholastics, we should understand evangelical virtues as created likenesses in the soul to the divine nature (2 Pet. 1:4). So too with simplicity (2 Cor. 1:12). Therefore, Scripture’s exhortations to wholeheartedness, simplicity, and sincerity are vectors pointing us to God’s simplicity. The paper concludes by reframing contemporary discussion of this attribute along exegetical and moral lines, and suggesting reasons why the attribute has become distorted from its Nicene form.
