The Didache (pronounced did-a-kay) is an early church document, and the word comes from the Greek didoskolos meaning teacher. It was possibly written around A.D. 65-80 and is supposed to be what the twelve apostles taught to the Gentiles concerning life and death, church order, fasting, baptism, prayer, etc. There is debate as to its authenticity. The work is cited by Eusebius who lived from 260-341 and Athanasius (293-373). The Didache is not inspired but is valuable as an early church document. (Full text of the didache).
