Anti-Donatist Writings: Writings in connection with the Donatist Controversy
This modernized edition brings together Augustine’s three anti-Donatist writings, presenting his most extended engagement with the Donatist controversy in clear, contemporary English for students, pastors, and readers of historical theology. The Donatist controversy arose in the aftermath of the Diocletianic persecutions and centered on the question of whether the moral failure of clergy invalidated the sacraments they administered. From this dispute emerged a lasting schism, with Donatist communities claiming to represent a pure church set apart from a compromised wider communion. Augustine’s response addresses these claims directly and at length. This revision was prepared through an AI-assisted process, combining digital tools with traditional editorial work.

Anti-Manichaean Writings: Writings in connection with the Manichaean Controversy
These writings arise from Augustine’s long and personal involvement with Manichaeism, a movement he followed for years before his conversion to Catholic Christianity. As a result, his critique is shaped not only by formal theological argument, but also by an intimate knowledge of the system’s internal logic, moral claims, and intellectual appeal. Across these treatises, Augustine confronts the Manichaean vision of the world as a conflict between coeternal principles of light and darkness. He defends the unity and goodness of the Creator, the integrity of the material world, and the coherence of the biblical account of creation, while developing a sustained reflection on the nature of evil, human will, and moral responsibility.

Anti-Pelagian Writings, Volume One: Original Sin, Nature, and Grace
When Pelagius began teaching that human beings possess the natural ability to live righteously without the special grace of God, his ideas quickly sparked debate across the Christian world. Augustine of Hippo emerged as the most important theological voice responding to these claims, arguing that the Pelagian view underestimated the depth of human sin and misunderstood the necessity of divine grace. The treatises collected in this volume represent the early stage of Augustine’s response to Pelagian teaching. In them, he develops arguments that would become foundational for Western Christian theology: that humanity shares in the fallen condition of Adam, that the law cannot produce righteousness apart from the Spirit, and that salvation depends entirely on the grace of God given through Jesus Christ.

Anti-Pelagian Writings, Volume Two: Grace, Free Will, and Predestination
By the time these works were written, the Pelagian controversy had moved beyond its earliest debates. Augustine had already defended the reality of original sin and the necessity of divine grace. Now new questions pressed in from every side. If grace is necessary for salvation, what role remains for human choice? Why do some believe while others do not? And why do some who begin the Christian life fall away while others persevere to the end? In these later anti-Pelagian writings, Augustine confronts those questions directly. On Marriage and Concupiscence addresses the relationship between the goodness of marriage and the fallen condition of human desire. A Treatise on the Soul and its Origin explores difficult questions about human nature and the transmission of sin. A Treatise against Two Letters of the Pelagians answers critics who sought to dismantle Augustine’s theology of grace. The remaining works present Augustine’s mature reflection on grace and salvation. In A Treatise on Grace and Free Will and A Treatise on Rebuke and Grace, Augustine explains how divine grace enables rather than destroys human freedom. Finally, A Treatise on the Predestination of the Saints and A Treatise on the Gift of Perseverance examine why faith itself must be understood as a gift of God and why perseverance in the Christian life ultimately depends on divine grace.

The City of God, Volume One: The Refutation of Pagan Religion (Books 1–10)
Written in the aftermath of Rome’s fall, Augustine’s City of God confronts the charge that Christianity was responsible for the empire’s decline and exposes the theological emptiness of pagan religion. In the first ten books of The City of God, Augustine addresses one of the central accusations of his age: that the abandonment of the traditional gods had brought disaster upon Rome. With historical argument, theological reasoning, and sharp rhetorical skill, he demonstrates that Rome’s gods neither preserved the city from calamity nor provided moral transformation or true happiness to their worshipers.

The City of God, Volume Two: The Origin, History, and Destiny of the Two Cities (Books 11–22)
In the second half of The City of God, Augustine moves beyond refutation to construct one of the most influential Christian interpretations of history ever written. Following his critique of pagan religion in the opening books, Augustine turns in Books 11–22 to a positive exposition of Christian doctrine. He traces the origin of the two cities—the City of God and the earthly city—to the beginning of creation, locating their division not in political structures but in the fundamental orientation of love toward God or toward self. Augustine develops this vision across the sweep of history. He reflects on the fall of angels and humans, the nature of death and sin, and the role of Christ as the true mediator. Sacred history is set alongside secular history, as the people of God move through time within, not apart from, the rise and fall of earthly powers.

These reflections reveal Augustine not only as a penitent believer, but as a profound biblical theologian whose thought would shape Christian doctrine for centuries.

Exegesis of the Gospels: Sermon on the Mount and Harmony of the Gospels
In his commentary on the Sermon on the Mount, Augustine works methodically through Matthew 5–7, treating the text not as a collection of isolated sayings but as a coherent whole. He explores the moral vision of the sermon, the formation of Christian virtue, and the relationship between outward obedience and inward transformation. The result is a sustained reflection on the shape of the Christian life grounded in the teaching of Jesus. In The Harmony of the Gospels, Augustine turns to a different but related task. Confronted with variations among the Gospel accounts, he examines questions of order, detail, and emphasis, seeking to show how the evangelists may be read together without contradiction. Rather than erasing differences, he accounts for them, arguing that each Gospel contributes to a unified and trustworthy witness to the life of Christ.

Homilies on the Gospels
These sermons differ in tone and purpose from Augustine’s formal theological treatises. Here he speaks as a pastor addressing a gathered congregation, moving directly through Gospel texts and drawing out their meaning for daily life. His aim is not only to explain, but to persuade—to call his hearers to repentance, to strengthen their faith, and to guide them in the practice of Christian virtue. Across these homilies, Augustine returns again and again to central themes: the necessity of humility before God, the danger of pride, and the primacy of love as the fulfillment of the law. The person of Christ stands at the center of his preaching, not only as teacher but as the one in whom salvation is found. The result is exposition that is at once theological, moral, and deeply practical. At the same time, these sermons offer insight into Augustine’s interpretive approach. He reads the Gospels as a unified witness, frequently connecting passages and drawing out their broader significance. His use of figurative interpretation appears alongside more direct explanation, all directed toward helping his hearers understand and live out the text.
