Didache

The Didache is the oldest known Christian handbook, a window into the faith and practice of the first generations who followed Jesus. Likely composed in the late first century CE, it predates most of the New Testament and gives us something invaluable: not theology abstracted from life, but instructions for how to actually be a Christian in the messy, dangerous early years. The text moves from the Two Ways (life and death, light and darkness) to the rituals that bound communities together: baptism, fasting, prayer, and the Eucharist. It addresses church organization, treatment of prophets, and the expectation of the Lord's return. Lost to history and referenced only in other ancient texts, it sat hidden for fifteen hundred years until a manuscript surfaced in a Turkish library in 1873. For anyone curious about where Christianity came from and what the first Christians actually believed and did, this is as close as we can get to hearing them speak.
