I understand that some elements in this Church Crisis are difficult, and many problems don't have definitive answers.
But at least this one small issue -- regarding 2 priests and their status -- has been proven or settled: Fr. Zendejas and Fr. Garcia ARE resisting the SSPX, and have the full approval of Bishop Williamson.
How much that means to each person depends on his own wisdom, beliefs and free will.
Remember, even Our Lord couldn't win everyone over, not even by working miracles. How did the bad-willed react? They blasphemously claimed He was working miracles by the power of satan.
That's fallen human nature and free will for ya. You can't force people to be good, and you can't force people to follow the truth.
