Addressed to early Christians on the subject of repentance and forgiveness, this volume provides a key text on postapostolic practical theology. The second treatise, On Purity is one of Tertullian’s most virulent anti-Montanist treatises.

During its first four centuries, Christianity produced some of the world’s most profound historical, theological, and philosophical literature. This collection comprises an enormous selection of their work, including heart-wrenching martyrdom narratives, intimate letters, remarkable biblical commentaries, and profound philosophical and theological treatises. Contributors include some of the most influential thinkers in world history—such as Justin Martyr, Athanasius, Augustine, and Jerome—as well as lesser-known and controversial figures such as Origen, Maximus the Confessor, and Cyprian of Carthage.

Christianity spread quickly in the second century, and was defined by horrific persecution and rapid theological development. Through letters, treatises, and martyr narratives, postapostolic Christians documented their experience, and this collection comprises the most important documents they produced. It includes the famous apologies of Justin Martyr, the dramatic tale of Polycarp’s martyrdom, and other signififcant texts such as Arnobius of Sicca’s Against the Pagans, and The Octavius of Marcus Minucius Felix.
