Since it's rediscovery, the Didache has been important to early Christian studies. Between its views on ethics, the Eucharist, and baptism, the Didache has even forced itself into debates on the Synoptic Problem.
The Didache does refer to Jesus as the 'son' of God, the 'Lord', and the 'Christ'. It also says that God 'bestowed [...] everlasting life through your son'. It even associates the triadic formula 'in the name of the Father and of the son and of the holy spirit' with baptism.
However, there is no mention anywhere of the death or resurrection of Jesus. Notably, the Eucharist is present, but the bread and wine are distinctly not associated with Jesus' crucifixion. Instead, the wine is explicitly given as a metaphor for Jesus being a 'vine' (the messiah) which sprouted from David. Likewise, the bread appears to be a reference to Israel (the reunion after scattering being a common topic in the prophets).
Now concerning the Thanksgiving meal, give thanks in this manner. First, concerning the cup: We thank You, our Father, For the Holy Vine of David Your servant, Whom You made known to us through Your Servant; May the glory be Yours forever. Concerning the broken bread: We thank You, our Father, For the life and knowledge Which You made known to us through Your Servant; May the glory be Yours forever. As this broken bread was scattered over the mountains, And was gathered together to become one, So let Your Body of Faithful be gathered together From the ends of the earth into Your kingdom; for the glory and power are Yours forever. But let no one eat or drink of your Thanksgiving, unless they have been baptized; for concerning this is taught, "Do not give what is holy to dogs."
(Ivan Lewis translation)
This seems completely incongruent with how Jesus is presented in the Synoptics, or anywhere else in the new testament texts, which at least initially calls into question the usual claim that the Didache simply borrowed from one or all of them. I can imagine this would indicate the Didache was either so early it was written before the Eucharist became definitively identified with Jesus' death, or it could indicate the Didache independently inherited the same 'Q' traditions as the Synoptics alongside a distinct Christology.
When was the Didache written? What is the evidence for its date, and possibly place of origin?
