Augustine, the man with upturned eye, with pen in the left hand, and a burning heart in the right (as he is usually represented), is a philosophical and theological genius of the first order, towering like a pyramid above his age, and looking down commandingly upon succeeding centuries. He had a mind uncommonly fertile and deep, bold and soaring; and with it, what is better, a heart full of Christian love and humility. He stands of right by the side of the greatest philosophers of antiquity and of modern times. We meet him alike on the broad highways and the narrow footpaths, on the giddy Alpine heights and in the awful depths of speculation, wherever philosophical thinkers before him or after him have trod. As a theologian he is facile princeps, at least surpassed by no church father, schoolman, or reformer. With royal munificence he scattered ideas in passing, which have set in mighty motion other lands and later times. He combined the creative power of Tertullian with the churchly spirit of Cyprian, the speculative intellect of the Greek church with the practical tact of the Latin. He was a Christian philosopher and a philosophical theologian to the full.

“After the conviction and condemnation of the Pelagian heresy with its authors by the bishops of the Church of Rome,—first Innocent, and then Zosimus,—with the co-operation of letters of African councils, I wrote two books against them: one On the Grace of Christ, and the other On Original Sin. The work began with the following words: How greatly we rejoice on account of your bodily, and, above all, because of your Spiritual welfare.’“ Aeterna Press

The Christian Church has no shortage of revered figures and saints, but it is difficult to find one that had a more decisive impact on the course of the Church's history than Augustine of Hippo. Augustine was a bishop of Hippo Regius in Africa, but his works, sermons and writings helped hold the Church together even as the Western Roman Empire was in its death throes, to the extent that every major branch of Christianity recognizes him today. The Catholic Church has venerated him as a saint and a Doctor of the Church, Orthodox Christians also consider him a saint, and Protestants and Calvinists cite him as one of the fathers and inspirations of the Protestant Reformation. In many respects, Augustine has provided the theological bedrock for Christians for nearly 1600 years, and as theologian John Leith noted in 1990, "Augustine, the North African of Berber descent, is today the spiritual father of multitudes who are remote indeed from him racially, politically, and culturally." On the Grace of Christ and on Original Sin sets forth St. Augustine's beliefs on original sin. In particular, he believed that the grace of Christ was indispensable to human freedom, and he framed the concepts of original sin. Augustine's concept of original sin was expounded in his works against the Pelagians. However, St. Thomas Aquinas took much of Augustine's theology while creating his own unique synthesis of Greek and Christian thought after the widespread rediscovery of the work of Aristotle. Augustine's doctrine of efficacious grace found eloquent expression in the works of Bernard of Clairvaux; also Reformation theologians such as Martin Luther and John Calvin would look back to him as their inspiration.

We admire these men for their greatness, but the truth is Augustine grappled with sexual passions. Martin Luther struggled to control his tongue. John Calvin fought the battle of faith with worldly weapons. Yet each man will always be remembered for the messages he declared-messages that still resound today. John Piper explores each of these men's lives, integrating Augustine's delight in God with Luther's emphasis on the Word and Calvin's exposition of Scripture. Through their strengths and struggles we can learn how to live better today. When we consider their lives, we behold the glory and majesty of God and find power to overcome our weaknesses. If ever you are complacent about sin, if ever you lose the joy of Jesus Christ, if ever you are dulled by the world's influence, let the lives of these men help you recapture the wonder of God.

According to Augustine's doctrine of original sin, Adam's progeny share a collective guilt which, like an infection, spreads through wayward sexual desires, passing from parent to child. But is it fair to blame sinners if they inherit evil like a disease? In Stricken by Sin, Cured by Christ Jesse Couenhoven clarifies the logic and illogic of Augustine's controversial views about human agency. The first half of the book examines why Augustine believed we are trapped by evil, and why only Christ can save us. Couenhoven examines overlooked texts Augustine wrote at the culmination of his career and offers a novel reading of his views about whether we control our personal identities, what we should be held culpable for, and whether freedom is compatible with necessity. The second half of the book develops a philosophically and scientifically astute theory of responsibility that makes it possible to retrieve some of Augustine's most divisive claims. Couenhoven makes a case for the surprising thesis that a carefully formulated doctrine of original sin is profoundly humane. The claim that sin is original takes seriously our dependence on one another for essential aspects of character and personality, our ownership of cognitive and volitional states that are not simply products of voluntary choices, and our status as personal agents of evil. Attending to these aspects of our lives challenges the idea that each individual's moral and spiritual standing is up to her or him, and drives us to ponder not only the nature of our responsibility and the shape of the freedom we seek, but also the need for grace we all share.
