Irenaeus learned from Polycarp as a boy

For, while I was yet a boy, I saw thee in Lower Asia with Polycarp, distinguishing thyself in the royal court, and endeavouring to gain his approbation. For I have a more vivid recollection of what occurred at that time than of recent events (inasmuch as the experiences of childhood, keeping pace with the growth of the soul, become incorporated with it); so that I can even describe the place where the blessed Polycarp used to sit and discourse— his going out, too, and his coming in—his general mode of life and personal appearance, together with the discourses which he delivered to the people; also how he would speak of his familiar intercourse with John, and with the rest of those who had seen the Lord; and how he would call their words to remembrance. Whatsoever things he had heard from them respecting the Lord, both with regard to His miracles and His teaching, Polycarp having thus received [information] from the eye-witnesses of the Word of life, would recount them all in harmony with the Scriptures. These things, through, God’s mercy which was upon me, I then listened to attentively, and treasured them up not on paper, but in my heart; and I am continually, by God’s grace, revolving these things accurately in my mind.

Polycarp came to Rome and defended against the Marcionites

He it was who, coming to Rome in the time of Anicetus caused many to turn away from the aforesaid heretics to the Church of God, proclaiming that he had received this one and sole truth from the apostles,—that, namely, which is handed down by the Church.

Trinitarian salutation

We wish you, brethren, all happiness, while you walk according to the doctrine of the Gospel of Jesus Christ; with whom be glory to God the Father and the Holy Spirit, for the salvation of His holy elect, after whose example the blessed Polycarp suffered, following in whose steps may we too be found in the kingdom of Jesus Christ!

Chapter XXII

Polycarp’s relics are preserved for use in the Church

Accordingly, we afterwards took up his bones, as being more precious than the most exquisite jewels, and more purified than gold, and deposited them in a fitting place, whither, being gathered together, as opportunity is allowed us, with joy and rejoicing, the Lord shall grant us to celebrate the anniversary of his martyrdom, both in memory of those who have already finished their course, and for the exercising and preparation of those yet to walk in their steps.

Martyrdom of Polycarp
Chapter XVIII

Christ is the only one worshipped

… It is neither possible for us ever to forsake Christ, who suffered for the salvation of such as shall be saved throughout the whole world (the blameless one for sinners), nor to worship any other. For Him indeed, as being the Son of God, we adore; but the martyrs, as disciples and followers of the Lord, we worthily love on account of their extraordinary affection towards their own King and Master, of whom may we also be made companions and fellow-disciples!

Chapter XVII

Resurrection is of both soul and body

I give thanks that you have counted me worthy this day and this hour, that I should have a part in the number of your martyrs, in the cup of your Christ, to the resurrection of eternal life, both of soul and body, through the incorruption imparted by the Holy Spirit.

Martyrdom of Polycarp
Chapter XIV

We reign with Christ by faith

If we please Him in this present world, we shall receive also the future world, according as He has promised to use that He will raise us again from the dead, and that if we live worthily of Him, “we shall also reign together with Him,” provided only we believe.
