An excerpt from The Letter to the Church of Smyrna
I celebrate the glory of Jesus Christ as God, because he is responsible for your wisdom, well aware as I am of the perfection of your unshakeable faith. You are like men who have been nailed body and soul to the cross of Jesus Christ, confirmed in love by his blood.
In regard to the Lord, you firmly believe that he was of the race of David according to the flesh, but God’s son by the will and power of God; truly born of the Virgin and baptized by John, that all justice might be fulfilled; truly nailed to a cross in the flesh for our sake under Pontius Pilate and the Tetrarch Herod, and of his most blessed passion we are the fruit. And thus, by his resurrection he raised up a standard over his saints and faithful ones for all time (both Jews and Gentiles alike) in the one body of his Church. For he endured all this for us, for our salvation; and he really suffered, and just as truly rose from the dead.
As for myself, I am convinced that he was united with his body even after the resurrection. When he visited Peter and his companions, he said to them: Take hold of me, touch me and see that I am not a spirit without a body. Immediately they touched him and believed, clutching at his body and his very spirit. And for this reason they despised death and conquered it. In addition, after his resurrection, the Lord ate and drank with them like a real human being, even though in spirit he was united with his Father.
And so I am giving you serious instruction on these things, dearly beloved, even though I am aware that you believe them to be so.
and to the Son
and to the Holy Spirit:
as it was in the beginning,
is now, and will be forever. Amen
