In chapter 12 of his letter to the Philippians, Polycarp writes of the Father and “our everlasting High Priest”:

But may the God and Father of our Lord Jesus Christ, and Jesus Christ Himself, who is the Son of God, and our everlasting High Priest, build you up in faith and truth, and in all meekness, gentleness, patience, long-suffering, forbearance, and purity; and may He bestow on you a lot and portion among His saints, and on us with you, and on all that are under heaven, who shall believe in our Lord Jesus Christ, and in His Father, who raised Him from the dead. Galatians 1:1 Pray for all the saints. Pray also for kings,1 Timothy 2:2 and potentates, and princes, and for those that persecute and hate you, Matthew 5:44 and for the enemies of the cross, that your fruit may be manifest to all, and that you may be perfect in Him.
