Letter 17

Felix IIIUnknown|pope felix iii
From: Pope Felix III, bishop of Rome
To: Acacius of Constantinople, Patriarch
Date: ~484 AD
Context: Felix III, letter 6; the formal sentence of excommunication against Acacius, detailing all his transgressions before delivering the final judgment.

Felix, bishop of Rome, to Acacius of Constantinople.

We have enumerated your transgressions in previous letters; we enumerate them once more here before delivering the judgment that they require.

You received Peter Mongus of Alexandria into communion, knowing that he had been condemned by the Council of Chalcedon for rejecting the orthodox definition of Christ's two natures. You supported the Henotikon of Emperor Zeno, which deliberately papers over the Chalcedonian definition in a way that allows the heresy to persist under the disguise of a peace formula. You suborned the legates sent from Rome to address this situation, so that they returned without having accomplished their mission and were themselves compromised in their fidelity to their instructions.

Despite repeated admonition, you have not repented of any of these actions. You have remained silent in the face of charges that demanded a response.

We therefore declare, by the authority of blessed Peter whose unworthy successor we are, that Acacius is separated from the priestly honor and from Catholic communion. He has separated himself by his own actions; we do no more than make visible what he has already done.

Felix, bishop of Rome, minister of the judgment that truth requires
