Do you think St Athanasius would be a saint if he hadn't opposed the heretic Arius?
Do you think St. Thomas More would be a saint if he hadn't opposed the heresiarchs Luther & Henry VIII?
If St. Athanasius had kept quiet about Arius being a heretic he would be seen by history as appeasing & enabling heresy. The same goes for St. Thomas More.
If you are a clergyman or a leading lay person & you don't publicly oppose the Bergoglian heresy
Not only will you not become a saint you will be known as an appeaser and enabler of the worst heresiarch in history
