A participant in a BBC Radio Four religious programme some years ago stated that the doctrine of total depravity no longer has any credence in the Church and that only a few religious sects now adhere to it. Her point is well taken. Indeed, we could go further than this. Few of those who do give assent to the doctrine understand it or recognise its implications either for soteriology or social theory. Yet the Christian doctrines of total depravity and salvation and the Christian doctrine of social order are closely linked.

The doctrine of total depravity does not claim that non-believers are incapable of doing good or virtuous acts. While God is the source of all goodness and, without His grace, humans cannot achieve any true good (cf. Mt. 19:16–17), common grace allows virtuous thoughts and actions among non-believers. The doctrine teaches that the Fall affected every aspect of human nature, including intellect and reason. This contrasts with the Roman Catholic view, which holds that man’s reason remains essentially uncorrupted by the Fall. The Reformers rejected the nature/grace dualism underlying the Roman Catholic doctrine, which limited the Fall’s effects to man’s “spiritual” condition while leaving reason intact. Following Augustine’s doctrine of original sin, they taught that the Fall impacted the whole nature of man, including his reason. Therefore, in all thoughts and actions—virtuous or immoral—the non-believer thinks and acts in rebellion against God. As the Apostle Paul stated, “Whatsoever is not of faith is sin” (Rom. 14:23). Those who do not live by faith are in denial of God and in rebellion against Him. Their acts of charity and virtue, though good in themselves, serve the idols they choose instead of the God of the Bible. In every aspect of their lives, they deny the God who demands that their lives be lived in His service and for His glory. Non-believers’ virtuous thoughts and works are used to deny God and glorify idols. Their hearts are totally turned away from God, who is the author of all good (and the only one who is good, according to Jesus—Mt. 19:17). They are dead in trespasses and sins (Eph. 2:1) and cannot, without God’s grace, exercise faith (Eph. 2:8) or please God (Heb. 11:6).

The desire to be like God (Gen. 3:5, 22), defining good and evil without reference to Him, colors the entire outlook of fallen man. In all his thoughts and actions, he seeks to think and act independently of God, denying Him in every aspect of life. This orientation of denial determines how he lives in all spheres, interpreting the world without God. The corruption of sin manifests not only in morals and spirituality but also in his will, which is bound by sin, leading him to use reason to deny God. His defection from God is total; in this sense, man is totally depraved.

The doctrine of total depravity has profound implications for a Christian worldview. It affects not only our view of humanity’s slavery to sin and inability to serve God but also influences how we raise and educate children, provide welfare, organize society politically, and deal with criminals. In essence, it shapes how we apply faith to every aspect of life. As a foundational doctrine, total depravity aids in developing a consistently Christian perspective on the origin, nature, meaning, value, and purpose of life, based on the biblical doctrines of Creation, Fall, and Redemption. The biblical doctrine of the Fall presupposes Creation and rejects views like theistic evolution. Understanding the Fall—its extent and implications—is crucial in shaping our comprehension of salvation.

The Roman Catholic Doctrine

Medieval Roman Catholic theologians distinguished between the image of God in man—his natural ability to reason and exercise free will—and the likeness of God, which was his original righteousness in God’s sight. The likeness was considered a supernatural gift (donum superadditum) bestowed upon Adam in addition to his human nature. According to this doctrine, it was this supernatural gift that was lost in the Fall, breaking man’s communion with God. However, the image of God—man’s reason and free will—remained essentially uncorrupted by sin, though weakened. This led to a division between two realms: nature and grace. Redemption occurs in the realm of grace, not nature, which is largely unaffected by the Fall or Redemption.

This perspective denies man’s total depravity since the Fall, implying that sin is not pervasive and does not affect all of man’s thoughts, words, and actions outside of Christ. Salvation through Christ does not bring about a total transformation of man’s natural life by God’s grace but restores the donum superadditum, serving as a supplement to complete man. In this view, man can, by his own will and abilities, accomplish much of what God requires intellectually, morally, politically, and culturally. However, he cannot achieve supernatural righteousness in God’s sight without God’s grace. This grace is necessary to restore communion with God and to understand the supernatural revelations in Scripture. Meanwhile, the “book of nature” is accessible to all, and through natural abilities, people can attain a proper understanding of it.

In this perspective, which is associated with Roman Catholicism and particularly Thomas Aquinas, man is not totally depraved but only partially fallen. He retains natural abilities like reason and free will, which are not entirely corrupted by sin. According to Aquinas: “The constitution of human nature is neither destroyed nor diminished by sin. The gift of original righteousness was totally lost through the sin of our first parent. The natural inclination to virtue is diminished by sin.” For him, original sin is desire not subject to reason, and sin is “to fall short of the good which befits one according to one’s nature.” Man’s nature is impaired more in the desire for good than in the knowledge of truth, but “human nature is not so entirely corrupted by sin as to be deprived of natural good altogether.” Consequently, “grace does not abolish nature but perfects it.”

Therefore, salvation does not totally transform man’s life and culture but merely perfects them, as they are not perceived as completely fallen. The curse of sin has not entirely corrupted man’s natural life and culture. Man needs saving from sin, rebellion against God, and unbelief, but this is seen narrowly, relating to faith and morals. The Fall is viewed in “religious” terms, and areas considered part of nature are deemed religiously neutral. In this perspective, the Christian faith is a synthesis of nature and grace, with grace completing nature.

Except in areas perceived as “religious,” salvation in such a worldview will not affect the social order. Since man retains his natural abilities intact (e.g., intellect, reason, and free will), his culture and social order are not completely transformed by God’s grace in Christ; only his “spiritual” condition needs correction.

This illustrates that our understanding of the nature and extent of the Fall shapes our understanding of Redemption. If the Fall is total and affects every aspect of man’s life, then Redemption must be total, redeeming and transforming the whole of man’s life. There can be no area of human life or thought that is not to be redeemed by Christ. If the Fall is partial, affecting moral inclinations and faith but not intellect, then natural life is not wholly corrupted, and Redemption is partial, merely perfecting nature rather than transforming it entirely.

The Modern Protestant Doctrine

The Roman Catholic doctrine views Adam’s original righteousness as a donum superadditum, a supernatural gift added to human nature, which was lost in the Fall. This means man’s natural abilities—reason and free will—remain uncorrupted by sin. The Reformers rejected this view and taught the doctrine of total depravity, asserting that sin affects every aspect of human nature, including the intellect. Abraham Kuyper emphasized that sin darkened the intellect and that regeneration transforms both will and consciousness.

Despite this, many Protestants today hold a perspective similar to the Roman Catholic understanding. They are dualists, splitting life into spiritual (grace) and secular (nature) realms. They believe nature doesn’t need redeeming because it isn’t fallen, so conversion affects only the spiritual realm. The Church focuses on the supernatural, often advising congregations not to engage with cultural or worldly concerns. This dualistic worldview has led to pietism, now dominant among Protestants.

Even among those who consider themselves Reformed, the implications of total depravity for areas outside theology and church life are often neglected. In education, politics, economics, art, and culture, faith is seen as largely irrelevant and not requiring transformation. Practically, Reformed believers today have adopted a ...
