Written in the shadow of persecution and schism, On the Unity of the Church is one of the earliest and most passionate arguments for the visible unity of the Christian community. Cyprian of Carthage, a third-century bishop and martyr, addresses his flock not with abstract theory but with urgent pastoral care: the Church is one body, one bride, one ark of salvation, and to tear it apart is to cut oneself off from life itself. This edition renders Cyprian's classic in clear, inviting modern English while remaining faithful to the meaning and spirit of the original. With a helpful introduction, a glossary of names and terms, and key passages for reflection, it offers today's reader a direct encounter with a voice that has shaped Christian thought for seventeen centuries.
