What's really interesting is that according to the Catholic Church, believing that Mary was born without sin is required for salvation.

Not true. The Church believes that Protestants can be saved without becoming Catholic, and without believing that Mary was born sinless.

In the MUNIFICENTISSIMUS DEUS, Pope Pius XII writes...

"Hence if anyone, which God forbid, should dare willfully to deny or to call into doubt that which we have defined, let him know that he has fallen away completely from the divine and Catholic Faith."

"It is forbidden to any man to change this, our declaration, pronouncement, and definition or, by rash attempt, to oppose and counter it. If any man should presume to make such an attempt, let him know that he will incur the wrath of Almighty God and of the Blessed Apostles Peter and Paul."

I'll try and find the specific reference to salvation requiring belief in Marian stuff, but this right here is pretty amazing. According the Pope Pius XII, I've completely fallen away from the diving and the Catholic Faith, and I'm going to incur the wrath of God, Peter and Paul. Amazing.
