Written sometime between the mid-1st century and early 2nd-century AD, the Didache (or “Teachings of the Twelve Apostles”) is one of the most important early Christian writings to have been left out of the New Testament Canon. The text includes some of the earliest practical rules for the emerging institution of the church but describes a decidedly primitive stage in Christian development. John Hamer of Toronto Centre Place will review the text and consider the community that produced it. Why was it left out of the Bible and does it have anything to teach Christians today?
