I make much, in these pages, of the chains of teaching that lead us from the Apostles, through the Fathers, to our own day. A classic example is Polycarp’s discipleship to John, and Irenaeus’s to Polycarp, and Hippolytus’s to Irenaeus … And suddenly we’re in the middle of the third century! Kevin at Biblicalia makes another important connection tracing the famous “Two Ways” teaching from the earliest texts (Didache and Barnabas) all the way to Irenaeus. Check it out.
