>>While (to my knowledge) no one has ever stated that a person must honor Mary in order to gain salvation,<<

'We pronounce, declare, and define it to be a divinely revealed dogma: that the Immaculate Mother of God, the ever Virgin Mary, having completed the course of her earthly life, was assumed body and soul into heavenly glory. Hence, if anyone, which God forbid, should dare wilfully to deny or call into doubt that which we have defined, let him know that he has completely fallen 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' (Munificentissimus Deus [A.D. 1950], 44-45, 47; taken from Selected Documents of Pope Pius XII [Washington: National Catholic Welfare Conference])

So, when it says there that if a Catholic willfully goes against a dogmatic teaching of the Church, they thereby separate themselves from the Catholic Church, you somehow interpret that to mean that the Catholic Church is judging that person to be denied salvation by God?

That is NOT what it says. In fact, the Catholic Church has never presumed to do God's job of judgment on ANYONE -- not even Judas Iscariot.

The Catholic Church teaches that judgment and salvation are solely the province of Almighty God.

There is a HUGE difference between that and the quote you provided, which says that Catholics who willfully go against dogmatic Church teachings effectively remove themselves from good standing in the Church.
