The Didache, translated as the Teaching of the Apostles, is a very early Christian text. Scholars vary on dating this work any where from 70 AD to 140 AD. It was used to catechize (sp) early converts and it also includes rubrics for worship. That makes a combination of the catechism and the sacramentary, or so it seems to me

.
It is in the Didache that we find the (perhaps earliest) additon of the doxology to the “Our Father”. Our Protestant Brethren add this almost every time they recite the Lord’s Prayer, we generally add it only when we recite the Lord’s Prayer at mass…“For thine is the Kingdom, the Power and the Glory forever, Amen.”
In the Didache we find a list of sins that includes pedophelia (don’t we wish our priests and bishops had held fast to that tradition!) and abortion (how many catholics just don’t see that as sinful, just a matter of personal opinion or choice!).
In the Didache we have the instructions on how to baptize, preferably in ‘living’ water (rivers/streams), warm water (ponds/baths) and if necessary by spinkling where abundant or large valumes of water are unavailable. Ther persons being baptized, their sponsors and the minister of the baptism are called to fast before the event along with as many of the community that are able to participate.
There is a very early version of the Eucharistic Prayer that is very beautiful. When I read ti, it was not the differences to our present versions that caught my attention. What grabbed my heart was how similar and true to the meaning that version was to what is said in mass every Sunday. The version in the Didach is shorter and the wine is consecrated first, then the bread but the essence is the same, jsut as Jesus is the same yesterday, today and tomorrow.
Those early CHristians were encouraged to fast on Wednesday and Friday not Tuesday and Thursday as the ’ hypocites’ did. This is probably the distinction between the Jewish fast practices and the young Christian community that was in the process of becoming a distinct religious sect.
I actually enjoy reading, studying and reflecting with the Didache.
