Bellarmine and Baronius followed Pighius in denying that Honorius was condemned at all.
Denying the plain fact the Acts show Pope Honorius I was anathematized for heresy is playing fast and loose with semantics.
Anathema, the Honorius the heretic!
Doesn't do enough for you.
Even if St. Robert Bellarmine denied the Honorius was a heretic in plain ignorance of what the pope wrote, it doesn't change the fact he was anathematized by an ecumenical council of the Catholic Church. Sweeping Pope Honorius under the carpet sounds more like a cleanup effort or a bit like what a P.R. person does.
Perhaps we should follow the Coptic lead and rehabilitate "St." Dioscoros because he wasn't really a heretic. He was just misunderstood just like poor Pope Honorius.
This episode shows that a pope may err in his exercise of the papal office.
