Maybe since "you've read it" you can tell me how you've formed the conclusion that it is not from God. It's a relevant and accurate document. There are several people who have researched it and it's legit and has value in understanding the means, ways, and direction of the early church before the bible was compiled.
The dating of the Didache ranges between AD 50 -AD 120. It is the teachings of the Twelve Apostles. Didache means by 'the gospel.' It could even be that Barnabas was part of it's authorship.
John S. Kloppenborg Verbin comments on the Didache (
Excavating Q, pp. 134-135):
The
Didache, an early second-century Christian composition, is also clearly composite, consisting of a "Two Ways" section (chaps. 1-6),
a liturgical manual (7-10), instructions on the reception of traveling prophets (11-15), and a brief apocalypse.
I don't accept it as the inspired Word, but I do accept it as being authentic, accurate, having historical value, and not in opposition to God's Word.
