The early church — document discovered 1873 · orig. c. 100 AD

The Didache rediscovered

Ancient church manual found centuries later

In 1873, a Greek Orthodox bishop named Philotheos Bryennios is working in the library of the Holy Sepulchre Monastery in Constantinople when he finds a manuscript. He dates it to 1056 AD. Inside it, he discovers a document that the early church fathers had referred to but that scholars had believed lost for fifteen centuries.

The Didache — The Teaching of the Twelve Apostles — is the earliest church manual in existence. It was probably written around 100 AD, perhaps earlier. It describes in practical detail what a Christian community does: how to baptize, how to fast, how to pray the Lord's Prayer, how to celebrate the Eucharist, how to receive traveling teachers and apostles, how to test whether they are genuine, what a bishop is for.

It is an ordinary document. It is not theological speculation. It does not engage with the great heresies or the great councils. It is a practical guide for a community that has converted and is now trying to figure out how to live.

Read it and you are reading the instructions that some second-century community gave its newest members. Here is how you eat together. Here is what you say over the bread. Here is what to do if someone claims to be a prophet and asks for money.

Bryennios publishes his discovery in 1883. It electrifies the scholarly world. For the first time in fifteen centuries, you can read the instructions the early church gave its converts.

They are surprisingly practical. Surprisingly humble. Surprisingly ordinary.


You shall not kill. You shall not commit adultery. You shall not corrupt boys. You shall not fornicate. You shall not steal. You shall not practice magic. You shall not use enchantments.

The Didache, Chapter 2, c. 100 AD

Acts 2:42

They continued steadfastly in the apostles' teaching and fellowship, in the breaking of bread, and prayer.


The early church's instructions to new converts are strikingly practical. Don't kill. Don't steal. Don't do magic. Here is how to pray. Here is what to do at the table. Here is how to tell a genuine teacher from a false one.

There is no complicated theology here. Just the basics: how to live, how to pray, how to eat together, how to tell the truth from the lie.

Every generation of the church reinvents its catechesis — the process of forming new believers into the community and its practices. The Didache suggests that the essentials have always been the same: clear moral instruction, regular prayer, the shared table, and discernment about who to trust.

What does your community actually teach its newest members? And how does it compare to this ancient list?
