What is an acceptable situation in your parish?
1- Does your priest speak against the modernists, even if it is the Pope?
2- Does your priest show the reality of who Bishop Fellay is and what he is doing? If yes, does he condemn it?
3- Does he update people’s minds on the danger of what represents the actual position of the SSPX leadership?
If the answer is no I might consider it as a yellow light, but depending on the others circuмstances it still could be red light.
Now, dos the priest forbids you to take the actions mentioned above? If the answer is no you have two options:
1- Speak it out anyways and wait for them to take the decision
2- Leave and create the resistance yourself even if there is no priest, even if there is no one else with you.
You should never put yourself in a situation where you can’t speak out loudly no matter what. And it does not count to speak out anonymously on the Internet and not speaking out on your real life.
