On Exhortation to Chastity

Tertullian wrote this treatise around 210 to a recently widowed friend who was weighing whether to remarry. By this point in his life Tertullian had aligned himself with the New Prophecy, the Montanist movement that pressed for a stricter discipline than the mainstream church was willing to enforce, and the letter reflects that turn: it is harder in tone and argument than his earlier work to his own wife, Ad Uxorem, on the same subject.

The treatise lays out a threefold scheme of chastity — the virginity given from birth, the continence embraced after baptism, and the monogamy of a single marriage honored by not remarrying after a spouse's death. Tertullian concedes that Paul permits second marriage to those who cannot contain themselves, but he reads that permission as a bare toleration rather than a commendation, and he presses the logic further than Paul's text requires: remarriage, he argues, is a species of fornication, since the flesh that has once been joined and released should not seek a second union. He appeals to the discipline of pagan priesthoods and to Old Testament figures as witnesses that single marriage was honored even outside the full light of the gospel, and he insists that the Spirit now speaking through the Paraclete is leading the church toward a stricter standard than the apostolic concession allowed. Throughout, continence is presented not as a grudging renunciation but as a good that strengthens both flesh and spirit, freeing a person from the entanglements and griefs that a second household brings.

The work matters less as a devotional text than as a document in the history of Christian sexual ethics and in the trajectory from the mainstream church's practice toward Montanist rigor. It shows how quickly a moral argument can escalate once biblical permission is read as merely provisional, and it stands alongside its companion pieces, Ad Uxorem and the later De Monogamia, as a record of one of the earliest sustained Christian debates over second marriage. Tertullian's rhetorical skill — the sharp antitheses, the appeals to natural shame, the willingness to overstate a case for effect — is on full display.

Who should read this: students of patristic ethics and of Montanism, and anyone tracing the early church's shifting views on marriage and widowhood. It is not a work to hand to someone seeking pastoral comfort after bereavement, nor does it represent a position any major Christian tradition has adopted as normative; its value is historical and argumentative rather than devotional.
