Ecumenical councils do not pass binding decrees that the church is obligated to follow? Really? And you mean an Ecumenical council can be wrong about what is decreed? WOw, that’s good now I don’t have to accept vatican II anymore… :rolleyes
III Constantinople (Ecumenical) condemned Honorius in his official papal capacity as the bishop of Rome, not as a private theologian. The council specifically stated that Honorius had advanced heretical teachings, approved of them, and in a positive sense was responsible for disseminating them (and was not merely negligent, as some apologists still lie.) It condemned him by name as a heretic, anathematising him as such and excommunicating him.
To give a brief summary from the Council’s acts, which are quoted more fully later where it is clear that Honorius is being spoken of:
“We find that these documents [including those of Honorius] 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…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…To Honorius, the heretic, anathema!… [The devil] has actively employed them [including Honorius]…we slew them [including Honorius] with anathema, as lapsed from the faith and as sinners, in the morning outside the camp of the tabernacle of God. &c.”
If you have a principle, you need to follow it through to its logical conclusions.
ANd anything you except for this council gives precedent for those who wish to except certain teachings of Vatican II, so you better watch out…
