Letter 80
1. We rejoice in the Lord and glory in the gift of His Grace, Who has shown you a follower of Gospel-teaching as we have found from your letter, beloved, and our brothers' account whom we sent to Constantinople: for now through the approved faith of the priest, we are justifying in presuming that the whole church committed to him will have no wrinkle nor spot of error, as says the Apostle, "for I have espoused you to one husband to present you a pure virgin to Christ." [1 Cor 11:2] For that virgin is the Church, the spouse of one husband Christ, who suffers herself to be corrupted by no error, so that through the whole world we have one entire and pure communion in which we now welcome you as a fellow, beloved, and give our approval to the order of proceedings which we have received, ratified, as was proper, with the necessary signatures. In order, therefore, that your spirit in turn, beloved, might be strengthened by words of ours, we sent back after the Easter festival with our letters, our sons, Casterius, the Presbyter, and Patricius and Asclepias, the Deacons, who brought your writings to us, informing you, as we said above, that we rejoice at the peace of the church of Constantinople, on which we have ever spent such care that we wish it to be polluted by no heretical deceit.
The rest of the letter concerns the reconciliation of the bishops who condemned Flavian of Constantinople and accepted the Eutychian heresy. The pope insists that the names of Dioscorus of Alexandria, Juvenal of Jerusalem, and Eustathius of Berytus should be removed from the diptychs. He also gives instructions about Bishop Julian of Cos and Bishop Eusebius of Dorylaeum. The letter is dated to the Ides of April in the consulship of Adelfius [= 13 April 451].
