Polycarp’s Epistle to the Philippians is still extant, and is the only work of Polycarp which we have. (The Greek text is given in all editions of the apostolic Fathers, and with especially valuable notes and discussions in Zahn’s Ignatius von Antiochien, and in Lightfoot’s Ignatius and Polycarp, II. p. 897 sqq.; an English translation is contained in the latter edition, and also in the Ante-Nicene Fathers, Vol. I. p. 31–36.) The date of its composition it is very difficult to determine. It must have been written after the death of Ignatius (chap. 9), and yet soon after, as Polycarp does not seem to know all the circumstances attending that event (see chap. 13). Its date therefore depends upon the date of the martyrdom of Ignatius, which is a very difficult question, not yet fully decided. The attack upon false teachers reminds us of Marcion, and contains traits which seem to imply that Polycarp had Marcion in his mind at the time of writing. If this be so, the epistle was written as late as 135 a.d., which puts the date of Ignatius’ death much later than the traditional date (on the date of Ignatius’ death, see above, Bk. III. chap. 36, note 4). The genuineness of Polycarp’s epistle has been sharply disputed—chiefly on account of its testimony to the Ignatian epistles in chap. 13. Others, while acknowledging its genuineness as a whole, have regarded chap. 13 as an interpolation. But the external testimony for its genuineness is very strong, beginning with Irenæus, and the epistle itself is just what we should expect from such a man as Polycarp. There is no good reason therefore to doubt its genuineness nor the genuineness of chap. 13, the rejection of which is quite arbitrary. The genuineness of the whole has been ably defended both by Zahn and by Lightfoot, and may be regarded as definitely established.
