"Didache"
The Didache deals with the roads to life and death. According to the Didache, the path of life teaches to love only one God, love your neighbor as yourself, and a form of what we now know as the Golden Rule. Various teachings deal with seeing God as all-powerful, seeking Him day and night, not doubting whether His Word is true, keeping the commandments of God, confessing our sins, and coming into prayer with a clear conscience. This is seen as the path of life. The Didache is like a handbook for the early practice of Christianity.
