Dating back to the late first or early second century, the Didache provides instructions on Christian ethics, rituals like baptism and the Eucharist, and church organization. It's a window into the lives of the earliest followers of Jesus.

The text begins with the "Two Ways," the way of life and the way of death, offering moral guidance much like the Sermon on the Mount. It emphasizes avoiding vices such as hate, envy, abortion and murder.

Baptism in the Didache is described with a preference for living water, but flexibility is shown with other water sources. The method can be by immersion, pouring, or sprinkling, highlighting the adaptability of early Christian practices.

The Eucharist, or Lord's Supper, is detailed with instructions on prayer and thanksgiving. It reflects a communal meal where participants give thanks for the body and blood of Christ.

Church leadership is another focus, with instructions on appointing bishops and deacons. The Didache advises on how to discern true prophets from false ones, an important issue in a time when charismatic figures could influence communities.

The Didache also includes an eschatological section, warning of the coming of the Antichrist and urging Christians to be vigilant and prepared for the end times, echoing themes found in apocalyptic literature of the era.

The Didache's survival and rediscovery in the 19th century after being largely forgotten for centuries remind us how much of early Christian life remains to be explored.
