The Library

Forty Centuries of Christian Writing

1693 works catalogued century by century, from the literature the Bible was written among to the present — each with a note on what it is, why it lasted, and where to read it.

401–500

The Fifth Century

104 works

397–426

Latin

On Christian Teaching

De Doctrina Christiana

Augustine of Hippo · 354–430

How to read the Bible and how to preach it: signs and things, the rule of love as the test of any interpretation, and a final book on using classical rhetoric without being used by it.

Early Church · HermeneuticsMatthew1 Corinthians

426

Latin

On Grace and Free Choice

De Gratia et Libero Arbitrio

Augustine of Hippo · 354 – 430

Written for monks at Hadrumetum who had read Augustine on grace and concluded that correction was pointless, since nothing they did was theirs. He answers that scripture plainly commands and plainly promises, so both the will and the grace that moves it must be real, and that God crowns his own gifts in us.

413–426

Latin

The City of God

De Civitate Dei

Augustine of Hippo · 354–430

Begun after Rome fell in 410 and pagans blamed the Christians. Augustine answers with a history of two cities founded on two loves — one on love of God to the contempt of self, the other on love of self to the contempt of God — running intermingled to the end of the age.

Early Church · TheologyGenesisRevelationPsalms

426–427

Latin

The Retractations

Retractationes

Augustine of Hippo · 354–430

A review of his own ninety-three books in order of composition, correcting what he now thought wrong and explaining what he had meant.

Western · Review

c. 425–429

Greek

Commentary on John

Cyril of Alexandria · c. 376–444

A vast doctrinal commentary reading the fourth gospel as a sustained demonstration of the Word made flesh, with heavy emphasis on the eucharist as the flesh that gives life.

Alexandrian · CommentaryJohn

c. 427–428

Latin

In Praise of the Desert

De Laude Eremi

Eucherius of Lyons · c. 380 – c. 449

A letter to Hilary of Arles arguing that the wilderness is not empty but furnished — God met Moses in it, fed Israel in it, and sent his own Son into it — and that the island monasteries of Lérins are its western equivalent.

Western Monastic · LetterExodusMatthew1 KingsNumbers

c. 426–429

Latin

The Conferences

Collationes

John Cassian · c. 360–435

Twenty-four conversations with the elders of Egypt on the goal of monastic life, discernment, unceasing prayer, and the way the mind wanders even at prayer.

Western Monastic · Dialogue

428–429

Latin

On the Gift of Perseverance

De Dono Perseverantiae

Augustine of Hippo · 354 – 430

The last thing Augustine finished. Even holding on to the end is a gift, not an achievement — which means no one can know they have it, and the church prays for perseverance precisely because it cannot be secured. Answering monks in Gaul who said this made preaching pointless, he replies that preaching is one of the means by which the gift is given.

429

Greek

Homily on the Holy Virgin Theotokos

Proclus of Constantinople · d. 446

Preached in the Great Church with Nestorius sitting in the congregation, and deliberately: a cascade of titles for Mary as Theotokos, the loom on which the robe of union was woven, the bridge from God to men. Nestorius rose and answered it from the same pulpit.

Byzantine · HomilyLukeJohnIsaiahGalatians

428–429

Latin

On the Predestination of the Saints

Augustine of Hippo · 354–430

A late work written for monks in Gaul, arguing that even the beginning of faith is God's gift and not a human contribution that God then rewards.

Western · TheologyRomansEphesians

c. 400–430

Greek

The Letters

Nilus of Ancyra · d. c. 430

Over a thousand short letters to monks, officials, and bishops, most only a few lines: what to do about a brother who talks in chapel, why an official should not decorate a church he oppresses a province to pay for, how to read a psalm.

Egyptian Monastic · LettersMatthewPsalms1 CorinthiansProverbs

430

Greek

The Twelve Anathemas

Cyril of Alexandria · c. 376–444

Twelve propositions appended to a letter to Nestorius, each condemning a way of dividing Christ, and demanding subscription.

Alexandrian · Anathemas

c. 410–435

Made within a generation of the invention of the Armenian alphabet, and made for that purpose. Begun from Syriac, then revised against Greek manuscripts brought back from Constantinople and Alexandria after Ephesus.

Western · Poetry

c. 425–440

Greek

On the Spiritual Law

Mark the Monk

Two hundred short sentences on how the law works inside a person, insisting against one party that baptism gives everything and against another that nothing is received without being worked out — grace is complete and hidden, and is uncovered by keeping the commandments.

The Peshitta

The standard Syriac Bible, its Old Testament translated directly from Hebrew and its New Testament settled in the fifth century, replacing the Diatessaron.

The Acts and Canons of the Council of Ephesus

The Council of Ephesus

The record of a council that opened before the Syrian bishops had arrived, deposed Nestorius in a single day, and was then countered by a rival council that deposed Cyril. Eight canons, the reading of Cyril's second letter into the record, and the crowd of Ephesus escorting the bishops home by torchlight.

414–442

Greek

The Festal Letters

Cyril of Alexandria · c. 376 – 444

Twenty-nine annual letters announcing the date of Easter and the beginning of the Lenten fast to the churches of Egypt, each expanding into a treatise — on fasting, on the incarnation, on why Jews and Greeks read the same signs differently.

Alexandrian · LettersExodus1 CorinthiansIsaiahJohn

c. 437

Greek

The Cure of Greek Maladies

Theodoret of Cyrus · c. 393 – c. 460

Twelve books answering pagan objections a century after the temples closed, quoting some three hundred and forty pagan authors — many of them now lost apart from these pages — and asking why, if the philosophers were right, it is the fishermen's teaching that has filled the world.

Around a hundred and eighty very short sermons from Ravenna, built on antithesis and wordplay, and rarely longer than a few minutes to deliver.

Against Julian

Contra Iulianum

Cyril of Alexandria · c. 376 – 444

Armenian

The Life of Mashtots

Koriun

A pupil's account of the man who invented the Armenian alphabet: the years of searching, the vision of a hand writing on stone, the first sentence set down — to know wisdom and instruction — and then the schools, the translations, and an alphabet made for Georgian and Caucasian Albanian as well.

Refutation of the Sects

On God

The Book of Promises and Predictions of God

Quodvultdeus · d. c. 454

Written in exile at Naples by the bishop of Carthage, expelled when the Vandals took the city. It runs through scripture as a series of promises made and kept, and reads the catastrophe that has just happened to his own church as one more chapter rather than as the end.

447

Greek

Eranistes

Theodoret of Cyrus · c. 393–c. 460

Three dialogues against the view that Christ's humanity was absorbed into his divinity, arguing that the Word remained unchangeable and impassible while genuinely human.

The Falling Asleep of Mary

Transitus Mariae

Anonymous

The apostles are carried on clouds from wherever they are preaching to Mary's bedside in Jerusalem. She dies without pain, her soul is received by her Son, and the body is taken up before it can be buried — in some versions after a hostile bystander's hands are severed at the bier.

The Discourses and Canons

Shenoute of Atripe · c. 348 – c. 465

The Liturgy of Saint James

The church of Jerusalem

The eucharistic rite of Jerusalem, with the fullest of all ancient anaphoras: a long thanksgiving over creation, the Sanctus, the words of institution, and an explicit invocation of the Spirit on the gifts. It contains the hymn Let all mortal flesh keep silence.

c. 400–500

Hebrew and Aramaic

Leviticus Rabbah

The academies of Galilee

Thirty-seven homiletic units on Leviticus, each built outward from a verse elsewhere in scripture and arriving at the reading by a long route. It is preaching rather than commentary, and much of it is about poverty, charity, and the body.
