Yeah, but Jesus and the Apostles quoted the Old Testament largely from the Septuagint which contains the Deuterocanonical books of Scripture. 300-350 references to the Old Testament are taken from the Septuagint.
I don't know why you seem to disregard this fact, or the fact that several Church Councils determined the Canon of Scripture (including the Deuterocanonical books) at the end of the fourth century.
Some scholars wanted to include as Scripture the writing called the Didache. It is even quoted by some today as if it were an authority on the teaching on the early church or on the same level as the New Testament writings
Christians place importance on the actions of the early Church since peers of the Apostles would have best understood Apostolic Tradition. Since the Didache is one of the earliest known Church documents, it is of great importance in understanding Sacred Tradition. The Church has never regarded the Didache as the equivalent of Sacred Scripture. Nor has the Church ever regarded the teachings of any Church Father, or even any Doctor of the Church, to be inerrant. The Church only regards as inerrant Its dogmatic teaching.
Stop pretending that I didn't write what I wrote HERE and in my previous posts.
I've grown tired of riding in a boat with a one-armed boat-rower. Bye - bye!
