heresy response

The Commonitorium or Commonitory is a 5th-century Catholic treatise written under the pseudonym “Peregrinus” and attributed to Vincent of Lérins. It is known for Vincent’s famous maxim: "Moreover, in the Catholic Church itself, all possible care must be taken, that we hold that faith which has been believed everywhere, always, by all.” Vincent wrote the Commonitory c. 434 and died c. 445. This is the best treatise I have ever read. https://www.newadvent.org/fathers/3506.htm​

He also speaks of “cancelled” priests.
Chapter 4. [11.]
“... wives were violated, widows ravished, virgins profaned, monasteries demolished, clergymen ejected, the inferior clergy scourged, priests driven into exile, jails, prisons, mines, filled with saints, of whom the greater part, forbidden to enter into cities, thrust forth from their homes to wander in deserts and caves, among rocks and the haunts of wild beasts, exposed to nakedness, hunger, thirst, were worn out and consumed. Of all of which was there any other cause than that, while human superstitions are being brought in to supplant heavenly doctrine, while well-established antiquity is being subverted by wicked novelty, while the institutions of former ages are being set at naught, while the decrees of our fathers are being rescinded, while the determinations of our ancestors are being torn in pieces, the lust of profane and novel curiosity refuses to restrict itself within the most chaste limits of hallowed and uncorrupt antiquity?”
Chapter 5. [12.]
“But it may be, we invent these charges out of hatred to novelty and zeal for antiquity. Whoever is disposed to listen to such an insinuation, let him at least believe the blessed Ambrose, who, deploring the acerbity of the time, says, in the second book of his work addressed to the Emperor Gratian: Enough now, O God Almighty! Have we expiated with our own ruin, with our own blood, the slaughter of Confessors, the banishment of priests, and the wickedness of such extreme impiety. It is clear, beyond question, that they who have violated the faith cannot remain in safety.”

Vincent quoted Pope Stephen’s epistle sent to Africa: “Let there be no innovation — nothing but what has been handed down.”
