This would have been quite like Polycarp, who appears to have had a special horror of heretics. Compare his words to Marcion, quoted above, in Bk. IV. chap. 14. He seems to have inherited this horror from John the apostle, if Irenæus’ account is to be believed; see Adv. Hær. III. 3, 4, quoted by Eusebius in Bk. III. chap. 28, and in Bk. IV. chap. 14.
