TULIP and Reformed Theology: Total Depravity

By R C Sproul 

The doctrine of total depravity reflects the Reformed viewpoint of original sin. That term—original sin—is often misunderstood in the popular arena. Some people assume that the term original sin must refer to the first sin—the original transgression that we’ve all copied in many different ways in our own lives, that is, the first sin of Adam and Eve. But that’s not what original sin has referred to historically in the church. Rather, the doctrine of original sin defines the consequences to the human race because of that first sin.

WE ARE NOT SINNERS BECAUSE WE SIN. WE SIN BECAUSE WE ARE SINNERS. —R.C. SPROUL

Virtually every church historically that has a creed or a confession has agreed that something very serious happened to the human race as a result of the first sin—that first sin resulted in original sin. That is, as a result of the sin of Adam and Eve, the entire human race fell, and our nature as human beings since the fall has been influenced by the power of evil. As David declared in the Old Testament, “Oh, God, I was born in sin, and in sin did my mother conceive me” (Ps. 51:5). He was not saying that it was sinful for his mother to have borne children; neither was he saying that he had done something evil by being born. Rather, he was acknowledging the human condition of fallenness—that condition that was part of the experience of his parents, a condition that he himself brought into this world. Therefore, original sin has to do with the fallen nature of mankind. The idea is that we are not sinners because we sin, but that we sin because we are sinners.

In the Reformed tradition, total depravity does not mean utter depravity. We often use the term total as a synonym for utter or for completely, so the notion of total depravity conjures up the idea that every human being is as bad as that person could possibly be. You might think of an archfiend of history such as Adolf Hitler and say there was absolutely no redeeming virtue in the man, but I suspect that he had some affection for his mother. As wicked as Hitler was, we can still conceive of ways in which he could have been even more wicked than he actually was. So the idea of total in total depravity doesn’t mean that all human beings re as wicked as they can possibly be. It means that the fall was so serious that it affects the whole person. The fallenness that captures and grips our human nature affects our bodies; that’s why we become ill and die. It affects our minds and our thinking; we still have the capacity to think, but the Bible says the mind has become darkened and weakened. The will of man is no longer in its pristine state of moral power. The will, according to the New Testament, is now in bondage. We are enslaved to the evil impulses and desires of our hearts. The body, the mind, the will, the spirit—indeed, the whole person—have been infected by the power of sin.

I like to replace the term total depravity with my favorite designation, which is radical corruption. Ironically, the word radical has its roots in the Latin word for “root,” which is radix, and it can be translated root or core. The term radical has to do with something that permeates to the core of a thing. It’s not something that is tangential or superficial, lying on the surface. The Reformed view is that the effects of the fall extend or penetrate to the core of our being. Even the English word core actually comes from the Latin word cor, which means “heart.” That is, our sin is something that comes from our hearts. In biblical terms, that means it’s from the core or very center of our existence.

So what is required for us to be conformed to the image of Christ is not simply some small adjustments or behavioral modifications, but nothing less than renovation from the inside. We need to be regenerated, to be made over again, to be quickened by the power of the Spirit. The only way in which a person can escape this radical situation is by the Holy Spirit’s changing the core, the heart. However, even that change does not instantly vanquish sin. The complete elimination of sin awaits our glorification in heaven.
