c. 628–630

Greek

The Mystagogy

Attributed to Sophronius of Jerusalem · c. 560 – 638

A monk crossing the Jordan finds a naked, sun-blackened woman who levitates at prayer and knows scripture she has never read.

The Book of Zerubbabel

Anonymous

Written as Persians and Byzantines fought over Jerusalem.

The Qur'an

Recited by Muhammad; collected under Uthman · Muhammad, c. 570 – 632

The scripture of Islam, and unavoidably a book about Christians. Jesus is born of a virgin, works miracles, is the Messiah and a word from God, and is not the son of God; Mary has a sura to herself and is named more often than in the New Testament; the Trinity is rejected, and the crucifixion is denied with the words it only appeared so to them.

The Psephos and the Letter to Honorius

A patriarch's attempt to reunite an empire split by Chalcedon: stop arguing about one energy or two, he rules, and simply confess one will in Christ. The letter to Rome presents this as a settled peace and asks for agreement.

Greek

The Synodical Letter

Sophronius of Jerusalem · c. 560–638

Greek

The Christmas Sermon of 634

Sophronius of Jerusalem · c. 560 – 638

The patriarch of Jerusalem explains to his congregation why they cannot go the five miles to Bethlehem this year: the Saracens are on the road, and the sword of the godless is at the throat of the city. He tells them their sins are the cause and that repentance is the defence.

Latin

Letter to Sergius

Honorius I · d. 638

Rome's reply to Sergius, agreeing that the question should be dropped and adding the sentence that would cost him: we confess one will of our Lord Jesus Christ. He appears to have meant that Christ had no divided will, not that he had only one.

The Ecthesis

Heraclius, drafted by Sergius · Heraclius, c. 575 – 641

Posted in the narthex of Hagia Sophia. It forbids anyone to speak of one energy or two in Christ, and requires the confession of a single will — imperial law settling a question the councils had left open, in the year Jerusalem fell.

Greek

The Letters

Maximus the Confessor · c. 580 – 662

Greek

Apology Against the Jews

Leontius of Neapolis · c. 590 – c. 650

An answer to the charge of idolatry, arguing that Christians do not worship wood but honour what it depicts, as a man kisses a letter from an absent son and honours the son rather than the paper — and pointing to the cherubim God himself commanded for the ark.

The Sutra of Jesus the Messiah

Alopen and the Church of the East mission

The gospel explained to a Tang audience in Buddhist and Daoist vocabulary: God is the Emperor of Heaven, the Messiah is born of the Cool Breeze upon a chosen woman, and the duties owed are to God, to the emperor, and to one's parents, in that order.
