While I happen to agree with you - poor old Honorius likely would have come around to an orthodox view if he had just lived a few years longer, do you think the Council erred? Do you think they committed an injustice against Honorius?
Cordially,
Perhaps to be "Roman-ically correct," one should conclude that the council cannot err because it is infallible since it was certified by the pope. However not all council statements "define a doctrine regarding faith or morals to be held by the universal Church." Disciplinary action is not a definition of faith or morals. St. Joan of Arc was condemned to death by a council but was later exonerated. So disciplinary actions against individuals are not infallible. The condemnation of Honorius' heresy is infallible but not the condemnation of the man.
