“To fight against the errors of the age is a duty; to unmask the plots of the wicked is a holy work.” - St. Pius X
“If the faith is in danger, a subject ought to rebuke his prelate even publicly.” - (Summa Theologiae II-II, q. 33, a. 4)
“Pastors who fear to rebuke sinners earn for themselves the guilt of those sinners.” - St. Gregory the Great
“I have never spared heretics, and I have always striven to make the enemies of the Church my own enemies.” - St. Jerome
“The Church is infallible in matters of faith and morals; therefore she must condemn error.” - Pope Benedict XIV
“It is no less a duty to refute error than to defend truth.” - Pope Leo XIII
“Those who support error are its [the Church's] worst enemies.” - Pope Pius XI
“The Church is intolerant of error because she is the guardian of truth.” - Pope Pius XII
“Not to oppose error is to approve it.” - St. Basil the Great
“He who sees another in error and does not correct him becomes guilty of that error.” - St. Alphonsus Ligouri
“The Church must refute those who bring in destructive heresies.” - Origen
"He who does not call others back from error when he can, demonstrates that he himself is in error. " - Pope Leo I
The principle is:
Truth is a sacred trust, and therefore every Christian — from the highest pastor to the simplest believer — bears a grave duty to oppose falsehood, correct those who stray, and defend the faith with courage, for silence in the face of error is itself a participation in that error.
The post-Vatican II Eastern Catholics have ignored the above principle and for such reason, they are not to be considered anything but aligned with Vatican II.
Fleeing to the Liturgy of the Eastern Church because one can recognize orthodoxy in those places does NOT negate the above principle.
To align yourself with those who support heretics makes one at the very least, suspect of heresy themselves.
Of course, the crisis causes diverse reactions and different approaches - so any manner of running around and liturgical "shopping" or "looking for answers" is to be expected especially following such a massive collapse of a sense of the sacred and the spiritual free-for-all that ensued after the Vatican II revolution kicked-off.
The crisis continues and so do the various reactions.
