It is true that the Church can never lead us astray! Absolutely. The Church is both infallible, that it can never teach error, and indefectible, that it’s teaching can never change.
So then, if what the Novus Ordo believe and teach, if it differs from what the Church has always taught, cannot be a teaching of the Catholic faith. Religious liberty has been condemned: it cannot be Catholic teaching. Impossible. The Novus Ordo are largely ignorant of Catholic teaching, as they’ve never been taught Catholicism. There are many who don’t want to look, who just don’t care. But someone who stumbles across truth must pursue it. It is a sin against the Holy Ghost to resist the known truth. For those who are ignorant, ignorance excuses guilt, but it cannot make the action good. Do most NO pew sitters know what they are doing is wrong? I would say probably not. They don’t know any different. But that doesn’t make it ok just because they don’t know.
Of course, in the early days it was a matter of “obedience” to the bishops who said that we HAD to go along with the changes. False obedience! We cannot obey bad orders that lead us to sin! So the Novus Ordo use good Catholic thinking in the wrong scenario. Should Catholics obey the Popes and bishops? Absolutely! When they ask us to join their new religion? We must resist!
