Ignatius of Antioch, Dionysius of Corinth, Irenaeus, Gaius, Clement of Alexandria, Tertullian, The Little Labyrinth, The Poem Against the Marcionites, Eusebius of Caesarea, Peter of Alexandria, Lactantius, Cyril of Jerusalem, Optatus, Epiphanius of Salamis, Pope Damasus I, Jerome and Augustine say he did.
