Reading the lives of some Saints I discovered that often they obeyed their Bishops or other superiors even when the Bishop was wrong in their views.
They obeyed even though it did cause great spiritual and mental anguish to themselves. Because they knew that their rightness was known to God. This priest is surely speaking the truth and no doubt God will make sure that in good time the priest's message will be heard and embraced. Especially by the Bishop. Meanwhile the priest should bear the duty of obedience he promised with grace and humility.
You are absolutely correct!!
But at that time the Bishops were not part of Satan's conspiracy.
