This description of original sin is extraordinarily similar to the Reformed doctrine of total depravity. The Westminster Confession of Faith describes it this way, “By this sin they fell from their original righteousness and communion with God, and so became dead in sin, and wholly defiled in all the parts and faculties of soul and body“. They also call it, “original corruption, whereby we are utterly indisposed, disabled, and made opposite to all good, and wholly inclined to all evil” (WCF 6.2, 6.4).
The Extent of Original Sin
Vermigli’s depiction of original sin is that it is an entire corruption of human nature. It is a corruption entirely throughout, though not an entire corruption such that the mind and affections are utterly wicked. Rather, every aspect of human nature is twisted, and turned against God. Throughout his work Vermigli refers to it variously as a contagion, a kindling, a depravity, a corruption, an impurity, a weakness. With the mingling of these metaphors, Vermigli means to show that it is an insidious, powerful, and all-pervasive issue.
Original sin permeates the entire human person and “indwells” us. For this reason, original sin is often called “indwelling sin”. Indwelling sin is complicated and pervasive. Indwelling sin isn’t stagnant. It effects change in various elements of the human person, as each element relates to another. According to Vermigli, the faculties of the soul are intricately interrelated to one another, as well as intricately related to the body. Not only do the soul and body have effects upon each other, the various faculties of the soul have effects on each other. He points out that Augustine argued something similarly, saying, “From the corruption of the affections, the mind is blinded and the will corrupted.” That is, the body is supposed to obey the will, and the will submit to the mind. But, because of the complex interrelation of the faculties, and their corruption in original sin, this order is upended. “The body does not obey the mind to do good things, and that lusts are resistant to the mind and want to dominate it, and that reason is opposed to God” (p. 25).
This pattern of pervasive, indwelling corruption is not asked for by humanity. Though we do not ask for this, we still have it. Some might wonder why God would treat something unasked for as a sin, but it is sin in that it is against what is godly. “Those initial mental impulses and our corrupt nature are sins”…”when we are inclined to those things that God’s law forbids…it is indisputable that we must be said to sin” (p. 85)
