Orestes Brownson says in Vol. 13 of his Works:
"I have listened, with what patience I could, to the facts and arguments adduced to prove that the pope has erred in matters of faith; but even the great Bossuet was obliged to confess that he could not prove that any pope had ever erred when speaking ex cathedra and defining a point of faith, or condemning an error opposed to it. The strongest case is that of Pope Honorius, in relation to the two wills and the two operations in Our Lord. That the pope was negligent, and failed to do his duty by crushing out the insurgent error at once with the authority of St. Peter, nobody disputes; but that he did not fall into heresy or err in his own doctrine, the learned bishop Hefele fully concedes." p. 362
I go with Brownson.
Not only did Honorius not promote the heresy, he also did not enforce a new Protestant/Nestorian/Jєωιѕн mass, priesthood and sacraments steeped in Modernist, Marxist, liberal, and every other 'ism' on the entire Church.
The idea of using Honorius as the one example for comparison of the current situation - The Great Apostasy - is pretty limp stuff indeed.
