< Thirdly, there are two other issues in the text, both contained in the phrase “[Honorius] followed [Sergius’] view and confirmed his impious doctrines.” The latter phrase “confirmed his impious doctrines” does not, by itself, convict Honorius of heresy since one may confirm something either by silence (and, in this case, neglect) or by a pronounced teaching. Therefore, the key part of the phrase hinges on “followed his view”. If this phrase means that Honorius believed the heresy, then our position would be certainly wounded. However, if the phrase in question refers rather to Sergius’ disciplinary request to impose silence on the Church, then it is our opponents whose position is called into question. In point of fact, while it is true that the Latin has “sequi mentem ejus”, which is ambiguous, and may mean either view (i.e. either following Sergius’s heretical doctrine or following Sergius’ request for silence), the original Greek text, of which the Latin is a translation has, without any ambiguity, “followed the counsel.” (4)
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. >
