Introduction to This Volume
How this book is arranged
This is the fifty-second volume of a series that gathers the writings of the early Church in order of date, from the generation after the apostles down to the eighth century. This volume holds Augustine, The City of God, Books 19 to 22, and On the Trinity, from the period AD 399 – 426.
Within each work the text is divided into chapters and numbered sections, so that any passage can be found again and cited. The small bold figures in the text are the section numbers.
The translations
The text is in English only. Wherever a modern English version has been prepared for SermonIndex it is used here; otherwise the book prints an older public-domain translation. In both cases the wording is the translator’s own: older translations have not been altered beyond dividing them into sections. The sources for every work are listed at the back of the book, together with the licence under which each text is released. All the works in this volume are printed in older public-domain translations.
In this volume
Augustine was born at Thagaste in North Africa in AD 354. He taught rhetoric at Carthage, Rome and Milan, and after years as a Manichaean he was baptised at Milan by Ambrose in AD 387. He returned to Africa, was ordained a presbyter at Hippo about AD 391, and was bishop of Hippo from about AD 395 until his death in AD 430, while the Vandals were besieging the city. He wrote the Confessions, The City of God and On the Trinity, and a great body of sermons, letters and treatises against the Manichaeans, the Donatists and the Pelagians.
The treatise On the Trinity was written over some twenty years, between about AD 399 and AD 420. It is printed here in two parts. The first part sets out the faith of the Church in the equality of the Father, the Son and the Holy Spirit, and the second part searches for the likeness of the Trinity in the human mind.
