I. He praises the Emperor's piety and mentions Eutyches' appeal.
How much protection the Lord has vouchsafed His Church through your clemency and faith, is shown again by this letter which you have sent me: so that we rejoice at there being not only a kingly, but also a priestly mind within you. Seeing that, besides your imperial and public cares, you have a most devout anxiety for the Christian religion, lest schisms or heresies or other offenses should grow up among God's people. For your realm is then in its best state when men serve the eternal and unchangeable Trinity by the confession of one Godhead. What the disturbance was which occurred in the Church of Constantinople, and which could have so moved my brother and fellow bishop Flavian, that he deprived Eutyches, the presbyter, of communion, I have not yet been able to understand clearly. For although the aforesaid presbyter sent in writing a complaint concerning his trouble to the Apostolic See, yet he only briefly touched on some points, asserting that he kept the constitutions of the Nicene synod and had been vainly blamed for difference of faith.
