" Theologian Michael Vlach has done an admirable job chronicling the appearances of penal substitution in the writings of the fathers,9 citing Clement of Rome, Ignatius, the Epistle of Barnabas, the Epistle to Diognetus, Justin Martyr, Eusebius of Caesarea, Eusebius of Emesa, Hilary of Poitiers, Athanasius, Basil the Great, Gregory of Nazianzus, Ambrose of Milan, John Chrysostom, Cyril of Alexandria, Gregory the Great, Severus of Antioch, Oecumenius, and of course Augustine of Hippo. Vlach’s significant documentation spans the first ten centuries of the orthodox church. "
