The Church can discern in council the heresy of a man such that in virtue of canon 1364, it could declare him ipso facto no longer the holder of all the ecclesiastical offices he held.
The Church can discern in council whether a man was uncanonically elected or if he has no juridical claim to a title.
These “can”‘s apply to every person in the Church, yes, even the Pope; and to every office; yes, even the Papacy.
If the Church did not have this power, then Christ would have been one stupid God for creating such a disfunctional institution which had no remedy for the worst of problems.
I have spoke about this in my many articles on a Provincial Council and on the Council of Sutri.
If the Bishop truly wants to stop milking dissent and riding the wave of malcontent; then why is he crafting such lies and such implicit blasphemies against the Head of the Church, Jesus Christ?
Anyone who can reach out to him, should do so.
