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!

Martyrdom of Polycarp
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!

Martyrdom of Polycarp
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.

Polycarp
Epistle to the Philippians
Chapter V

Resurrection and Obedience are connected

But He who raised Him up from the dead will raise up us also, if we do His will, and walk in His commandments, and love what He loved, keeping ourselves from all unrighteousness, covetousness, love of money, evil speaking, false witness; …

Polycarp
Epistle to the Philippians
Chapter II

The Son is the Eternal Word of God

This is He who was from the beginning, who appeared as if new, and was found old, and yet who is ever born afresh in the hearts of the saints. This is He who, being from everlasting, is today called the Son’ through whom the Church is enriched, and grace, widely spread, increases in the saints, furnishing understanding, revealing mysteries, announcing times, rejoicing over the faithful, giving to those that seek, by whom the limits of faith are not broken through, nor the boundaries set by the fathers passed over.

Mathetes
Epistle to Diognetus
Chapter XI

Jesus is our exchange

By what other one was it possible that we, the wicked and ungodly, could be justified, than by the only Son of God? O sweet exchange! O unsearchable operation! O benefits surpassing all expectation! That the wickedness of many should be hid in a single righteous One, and that the righteousness of One should justify many transgressors!

Mathetes
Epistle to Diognetus
Chapter IX

God manifested himself

…no man has either seen Him, or made Him known, but He has revealed Himself. And He has manifested Himself through faith, to which alone it is given to behold God. For God, the Lord and Fashioner of all things, who made all things, and assigned them their several positions, proved Himself not merely a friend of mankind, but also long-suffering in His dealings with them.
