Library Ignatius of Antioch Epistles (Middle Recension)
Polycarp, Chapter 7: Request that Polycarp would send a messenger to Antioch
Seeing that the Church which is at Antioch in Syria is, as report has informed me, at peace, through your prayers, I also am the more encouraged, resting without anxiety in God, if indeed by means of suffering I may attain to God, so that, through your prayers, I may be found a disciple [of Christ]. It is fitting, O Polycarp, most blessed in God, to assemble a very solemn council, and to elect one whom you greatly love, and know to be a man of activity, who may be designated the messenger of God; and to bestow on him this honour that he may go into Syria, and glorify your ever active love to the praise of Christ. A Christian has not power over himself, but must always be ready for the service of God. Now, this work is both God's and yours, when you shall have completed it to His glory. For I trust that, through grace, you are prepared for every good work pertaining to God. Knowing, therefore, your energetic love of the truth, I have exhorted you by this brief Epistle.
