The book "Works related to the Donatist problem" is one of the important works of St. Augustine, Bishop of Hippo. In this work, Augustine examines the complex problem of Donatism that arose in the early Church. Augustine provides an argumentative account of the main aspects of this controversy, which arose out of a difference of opinion about crucifixion and episcopal sacramentality. Augustine carefully examines and summarizes the historical and theological aspects of the problem, trying to find a way to solve it. This book is an important source for a better understanding of the religious disputes of the early Christian era and the views of St. Augustine himself on the subject.
