< “The names of those men whose doctrines we execrate are …Sergius… Cyrus…Pyrrhus…Paul and Peter…and…Theodore…all of whom the most holy and thrice blessed Agatho, Pope of Old Rome…rejected, because they are 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…because of what we found written by him to Sergius, that in all respects he followed his view and confirmed his impious doctrines.” (9)
Again, if one carefully reads this text a number of things come to light. First and foremost, Honorius is not mentioned among those who are “minded contrary to our orthodox faith”; that is, “Sergius, Cyrus, Pyrrhus, Paul, Peter and Theodore”. He may share their punishment but not the reason for it. If he were a heretic and positively taught the doctrine of Monothelitism, our opponents must provide some plausible explanation why deference was shown to Honorius by not including him in the list of being “contrary to the orthodox faith”. Unless our opponents wish to appeal to the Bishop of Rome’s primacy and the supreme office that he held in the Church as a reason for Honorius’ omission, the alternatives are few and far between. >
< Fourthly, the Acts of the Lateran Council of 649 were dispersed widely throughout the East and West, and followed the same basic protocol as the Sixth Ecumenical Council at Constantinople and anathematized Sergius, Pyrrhus, and Paul, but, as my thesis has maintained, Pope Honorius’ name is curiously missing from the anathemas. The council even went on to assert that from the very beginnings of Monothelitism, no Roman Pontiff had departed from keeping the Catholic Faith.
Pope Leo II (682-683) confirmed the Council’s condemnation and stated:
“[Honorius] did not illuminate this apostolic see with the doctrine of apostolic tradition, but permitted her who was undefiled to be polluted by profane teaching.” (10)
“[Honorius did not] as became the apostolic authority, extinguish the flame of heretical teaching in its first beginning, but fostered it by his negligence.” (11)
“…he permitted the immaculate faith to be subverted.” (17)
Again, we see our thesis maintained. The first citation indicates that the Pope “permitted” the pollution of profane teaching, but did not teach it himself, while the second selection indicts Honorius for fostering the heresy by “negligence” - again, hardly a challenge to the definition of papal infallibility or even Honorius’ personal orthodoxy.
As already intimated above, while there is really little support for a refutation of papal infallibility here, we must be careful to appreciate that Honorius was not a saint. In fact, he was a negligent Pope who caused much damage to the Church, and the Council was right in condemning his actions.
"It is expressly said, in the Acts, that God cannot endure that rule of silence, “Et quomodo non indigneretur Deus qui blasphemebatur et non defendbatur.” “And how could God but be indignant, who was blasphemed and NOT defended?” (13)
Because of his negligence, the Sixth Ecumenical Council (and the third) at Constantinople (680-681) burned the letters of Honorius, called him a “heretic”, and anathematized him. Their actions were approved by Pope Leo II and their decisions confirmed again at the next two Ecumenical Councils.
The Council called Honorius a heretic, but it must be remembered that in the early Church the term “heretic” could have two meanings: to those who maintained and pronounced the error formally and/or materially and to those “who neither taught nor maintained error themselves, but were accessory to the pertinacity of heretics, whether by protecting them, by favoring them, or by not repressing.” (14) This latter sense of permitting heresy has been understood and “confirmed by several examples in antiquity.” (12)
This secondary “soft” sense of heresy is possible for any Pope just as it was for Honorius. A Pope can indeed be negligent in his office, but in and of itself, this does not necessarily mean that he is guilty of impugning an article of faith.
As far as the definition of papal infallibility, invoked at the First Vatican Council in 1870, is concerned, it permits a Pope being negligent while on the Papal throne but not, quite obviously, actually pronouncing error from it. >
