St. Jerome[3] mentions that St. Polycarp met at Rome the heretic Marcion in the streets, who resenting that the holy bishop did not take that notice of him which he expected, said to him, "Do you not know me, Polycarp?" "Yes," answered the saint, "I know you to be the firstborn of Satan." He had learned this abhorrence of the authors of heresy, who knowingly and willingly adulterate the divine truths, from his master, St. John, who fled out of the bath in which he saw Cerinthus.[4] St. Polycarp kissed with respect the chains of St. Ignatius, who passed by Smyrna on the road to his martyrdom, and who recommended to our saint the care and comfort of his distant church of Antioch, which he repeated to him in a letter from Troas, desiring him to write in his name to those churches of Asia to which he had not leisure to write himself. St. Polycarp wrote a letter to the Philippians shortly after, which is highly commended by St. Irenaeus, St. Jerome, Eusebius, Photius, and others, and is still extant. It is justly admired both for the excellent instructions it contains and for the simplicity and perspicuity of the style, and was publicly read in the church in Asia in St. Jerome's time. In it he calls a heretic, as above, the eldest son of Satan.
