They are inundated with heresy
Could you post just a few examples, out of this figurative inundation?
Surely, it will be a easy task.
Schism.
They excommunicate anyone they disagree with. They set themselves up to be a de-facto Pope of the whole Catholic world.
What part of that is Catholic?
By the way, Desmond, we don't need to have more than one grave error to conclude AVOID THIS GROUP.
Their bitter zeal and schism permeates most of their writings. They are very dangerous. They cause Catholics to become dogmatic Home Aloners, staying at home every Sunday even when they have a perfectly good Tridentine Mass a short distance away!
In this way they PROMOTE THE DESTRUCTION OF CATHOLIC SOULS.
I think that's enough error for me to say AVOID AT ALL COSTS.
Whatever "truths" they have can be found hundreds -- even thousands -- of other places. If the whole MHFM site went down, the world would lose NOTHING.
Just like Vatican II.
