The Ecclesiastical Writers that flourished in Those Days
1 At that time there flourished in the Church Hegesippus, whom we know from what has gone before, and Dionysius, bishop of Corinth, and another bishop, Pinytus of Crete, and besides these, Philip, and Apolinarius, and Melito, and Musanus, and Modestus, and finally, Irenæus. From them has come down to us in writing, the sound and orthodox faith received from apostolic tradition.
