Third Council of Constantinople, Sentence against the Monothelites

The holy council said:  After we had reconsidered, according to our promise which we had made to your highness, the doctrinal letters of Sergius, at one time patriarch of this royal god-protected city to Cyrus, who was then bishop of Phasis and to Honorius some time Pope of Old Rome, as well as the letter of the latter to the same Sergius, we find that these documents are quite foreign to the apostolic dogmas, to the declarations of the holy Councils, and to all the accepted Fathers, and that they follow the false teachings of the heretics; therefore we entirely reject them, and execrate them as hurtful to the soul.  But the names of those men whose doctrines we execrate must also be thrust forth from the holy Church of God, namely, that of Sergius some time bishop of this God-preserved royal city who was the first to write on this impious doctrine; also that of Cyrus of Alexandria, of Pyrrhus, Paul, and Peter, who died bishops of this God-preserved city, and were like-minded with them; and that of Theodore sometime bishop of Pharan, all of whom the most holy and thrice blessed Agatho, Pope of Old Rome, in his suggestion to our most pious and God-preserved lord and mighty Emperor, rejected, because they were minded contrary to our orthodox faith, all of whom we define are to be subjected to anathema.  And with these we define that there shall be expelled from the holy Church of God and anathematized Honorius who was some time Pope of Old Rome, because of what we found written by him to Sergius, that in all respects he followed his view and confirmed his impious doctrines.  We have also examined the synodal letter of Sophronius of holy memory, some time Patriarch of the Holy City of Christ our God, Jerusalem, and have found it in accordance with the true faith and with the Apostolic teachings, and with those of the holy approved Fathers.  Therefore we have received it as orthodox and as salutary to the holy Catholic and Apostolic Church, and have decreed that it is right that his name be inserted in the diptychs of the Holy Churches.
