Nicene and Post Nicene Fathers, Second Series, Volume XI: Sulpitius Severus, Vincent of Lérins, John Cassian.

The Early Church Fathers is one of the most important collections of historical, philosophical and theological writings available in English to the student of the Christian Church. These documents provide the most comprehensive witness to the development of Christianity and Christian thought during the period immediately following the Apostolic Era.

The Catholic edition of Early Church Fathers does not include the introductions, prolegomenae, and various interpretive comments made by the protestant editors of the Edinburgh edition. However, it retains all of the footnotes found in the printed editions.

He refers to the First Council of Ephesus, held in the summer and early autumn of 431, as having been held some three years previously to the time at which he was writing “ante triennium ferme.
