The Didache: Discovery and Circulation of an Ancient Church Manual

The Teaching of the Twelve Apostles, usually known by its shortened Greek name Didache, is an early Christian guide to life and worship. Its association with 1873 comes from Philotheos Bryennios's discovery of a Greek manuscript volume. It was kept in the library of the Monastery of the Holy Sepulchre in Constantinople's Phanar district, belonging to the patriarch of Jerusalem. The monastery's name and affiliation should not cause the discovery to be relocated to the city of Jerusalem.

The manuscript bound the Didache together with the Epistle of Barnabas, the Clementine letters, and other texts, totaling 120 leaves. At the end, the scribe Leon supplied his name and a date corresponding to June 11, 1056. Bryennios first published the Clementine letters in 1875; only in late 1883 did he publish an annotated Greek edition of the Didache in Constantinople. The ancient work's composition, eleventh-century copying, nineteenth-century discovery, and printing were four separate stages.

The manuscript preserves both the short title Teaching of the Twelve Apostles and the longer The Teaching of the Lord through the Twelve Apostles to the Gentiles. These titles express the teaching's authority and intended transmission, not a verifiable individual author's signature; the title alone cannot establish joint authorship by the twelve apostles. The text more closely resembles a manual for teachers and communities of believers, centered on living, baptizing, praying, and receiving visitors.

Modern research generally places it against the background of the later first to earlier second century CE, while the date of its final composition, place of origin, and editorial layers remain disputed. Shawn Wilhite stresses the difference between the age of traditional materials and the stage at which they were compiled into the existing work. He adopts an approximate formation window of 80–110 CE and suggests Antioch or northern Palestine as possible locations. These are scholarly working hypotheses, not the discovery of an exact authorial date.

The first six chapters organize ethical instruction around the way of life and the way of death. The way of life begins with loving God the creator, loving one's neighbor, and not doing to others what one would not wish to suffer, then addresses enemies, giving, speech, and family relationships. The text forbids murder, theft, false witness, and resentment, while warning against double speech and hypocrisy. Short instructions follow one another in a form suitable for memorization, teaching, and repeated practice.

Chapter Four turns religious demands into communal obligations: do not extend a hand to receive and withdraw it from giving; do not reject someone in need, but share property with fellow believers. When Chapter Seven turns to baptism, it first requires teaching the preceding material. This sequence places ethical formation before initiation. The manual concerns not merely assent to ideas, but the development of observable conduct within the community.

Chapter Seven prescribes baptism in the name of the Father, Son, and Holy Spirit, preferably in running water. Other water may be used if this is unavailable; warm water may replace cold, and if conditions are insufficient, water may be poured over the head three times. Baptizer and recipient should fast beforehand, with the recipient fasting for one or two days. The text establishes a common form while acknowledging different water supplies and practical circumstances.

Chapter Eight specifies fasting on Wednesday and Friday and recitation of the Lord's Prayer three times daily. Chapters Nine and Ten provide thanksgiving prayers, first for the cup and then for the broken bread, linking bread gathered into one with the gathering of the church; the unbaptized may not participate. Chapter Fourteen requires assembly on the Lord's Day for breaking bread and thanksgiving, preceded by confession and reconciliation of disputes. Ritual thus connects with communal schedules, membership boundaries, and interpersonal peace.

Chapter Eleven requires reception of visiting teachers whose teaching accords with what has already been received, while limiting itinerant messengers: they should normally stay one day, or another if necessary; staying three days marks one as a false prophet. On departure, they should take only enough food to reach their next lodging, and requests for money are a warning. Prophets must also be judged by their conduct, not merely their claims to inspiration.

Chapter Twelve makes separate arrangements for ordinary traveling believers, generally allowing hospitality for two or three days; an artisan wishing to settle should work for a living. Chapter Fifteen asks the community to appoint gentle, honest, tested bishops and deacons who are not greedy, recognizing their service alongside prophets and teachers. Itinerants and local offices coexist in the text, and these titles should not be mapped directly onto later established church hierarchies. The final chapter turns to watchfulness, urging believers to prepare for the Lord's coming.

Philip Schaff's 1885 monograph records translations and studies appearing quickly after publication. Harnack received Bryennios's edition and published an introduction, partial German translation, and further research in 1884. Hitchcock and Brown of Union Theological Seminary in New York also issued the Greek text with notes in March that year. Schaff's own volume brought together the original, an English translation, related documents, and discussion, enabling readers to compare texts rather than merely read news of a discovery.

Schaff also described different denominations seeking support for their institutions in provisions on baptism, prayers, bishops, and deacons, drawing opposing interpretations from the same manual. His account reflects nineteenth-century theological commitments, yet genuinely shows the discovery entering contemporary debate. The Didache's value lies in its specific early norms of life: they tell us how its author wanted a community to act, not that every ancient church necessarily followed them in full.
