Polycarp, a disciple of the Apostle John and Bishop in the church of Smyrna, died for his faith in Christ at the stake at the age of 86. His martyrdom is described in a letter from the Church of Smyrna to the faithful at Philomelion, and half-way through the account the words of his last prayer are given.
This is the prayer he prayed while facing his death at the hands of his persecutors for putting his faith and trust in the Lord Jesus Christ.
O Father of Your well-beloved and blessed Son Jesus Christ, through whom we have known You;O God of the angels and powers and of every living creature, and of all sorts of just men which live in Your presence, I thank You that You have graciously granted this day and this hour to allot me a portion among the numbers of martyrs, among the people of Christ unto the resurrection of the everlasting life, both of body and soul, in the incorruption of the Holy Spirit; among whom I shall be received in Your sight this day, as a fruitful and acceptable sacrifice, as You have heretofore prepared, often revealed and now fulfilled, most faithful God who can not lie. Wherefore for all things, I praise You, I bless You, I glorify You, through the everlasting High Priest, Jesus Christ, Your well-beloved Son, to whom with You and the Holy Spirit, be all glory, world without end.
