Saint Augustine's seminal work on heresy and orthodoxy remains one of the most influential theological treatises of all time. Drawing on a wealth of biblical and patristic sources, Augustine presents a comprehensive overview of the various doctrines and practices considered heretical by the Catholic Church in the late 4th century. This edition includes a valuable appendix by Gennadius of Marseille that further explores the topic of heresy in the early Christian church. Suitable for theologians, scholars, and anyone interested in the history of Christianity, this volume is an essential addition to any theological library.
