Well ... that's because the grace of God was acting in you, and you were corresponding with it, but this kind of garbage, these fallacies that average people are unable to dispel since they're not educated, it and have a confusing impact on people and inculcate attitudes of Old Catholicism in people.
Sadly, because of people like this, a significant percentage of today's R&R are very thinly-veiled smells-and-bells Old Catholics, many of whom may not even have the Catholic faith at this time, since they are rejecting the papacy as being the proximate rule of faith except for regarding the extremely rare solemn dogmatic definition.
So they still need to be exposed for who they are.
My dad had a boyhood friend who always said, "There's a Catholic way to do everything." And canonizing heretics / apostates just doesn't seem like that Catholic way. Go figure.
The thing about using Honorius as an example is that the anathema shows exactly what the Church thinks about even
the whiff of heresy. Honorius and his failings are a spit wad compared to the nuclear h0Ɩ0cαųst detonated daily by the 'canonized popes' of late. There is no comparison or, it could be said, just a really, really crappy one.
