“To Honorius, the heretic, anathema!“
In Session XVI of the Sixth Ecuмenical Council (680–681), Honorius I was formally labeled a “heretic”, alongside other Monothelite leaders, yet he remained pope until his death. The council’s acclamation reads verbatim:
“To Theodore of Pharan, the heretic, anathema!
To Sergius, the heretic, anathema!
To Cyrus, the heretic, anathema!
To Honorius, the heretic, anathema!
To Pyrrhus, the heretic, anathema!
To Paul, the heretic, anathema!
To Peter, the heretic, anathema!
To Macarius, the heretic, anathema!
To Stephen, the heretic, anathema!
To Polychronius, the heretic, anathema!
To Apergius of Perga, the heretic, anathema!
To all heretics, anathema!
To all who side with heretics, anathema!”
— Nicene and Post‑Nicene Fathers, Second Series, Vol. XIV: The Sixth Ecuмenical Council, Session XVI
The council language itself used the word “heretic” in association with his name.
The dogmatic decree itself (as recorded in Mansi, Sacrorum Conciliorum, Tomus XI, cols. 635‑637) also states:
“…Honorius, qui fuit Papa antiquae Romae… haeretico anathema…”
English: “…Honorius, who was Pope of Old Rome… anathema to the heretic…”
The Council repeatedly identified Honorius as a heretic, both in the acclamations of the bishops and in the formal dogmatic decree
