Considering that Yah'shua is the Jewish Messiah. The twelve Apostles were all Torah observant messianic Jews. The only teaching of the apostles was the Tanach. The Didache is highly suspect.
shalom b'SHEM Yah'shua HaMashiach
“The Didache is highly suspect.”
If the Didache is suspect, then so is Euripedes, who dates far later, whom you cited to claim that that passage is a late addition. IOW, part of a conspiracy to keep you guys down. And if Ignatius is suspect too, who predates both the Didace and Euripedes, then there is nothing suspect also. Thus we are left again with the scripture, and again with the phrase “In the name of the Father, Son and Holy Spirit,” whether your sophistry approves of it or not.
