The Novus Ordo sectarian religion is far from being Catholic itself, so it wouldn't surprise me if they could successfully "refute" (in their own minds) no salvation outside of the Church. See, it's easy to refute something regarding the faith when you don't realize that it's condemned to do so and all of your opinions are heresies. That is what N.O. Catholics do. They condemn you and call you a heretic, schismatic, etc. and deny your Catholicity, all the while maintaining the heresies of "imperfect" communion with heretics.
Quite frankly, I'm astonished at how anyone can talk about "imperfect" communion. Are the Protestant heretics INSIDE of the Church or not? No? Then they are not "in communion" with the Church, PERIOD. To be in communion with the Church, you have to be INSIDE of it. No one would ever say that excommunicants are in communion with the Church. That's ridiculous. They are not in the Church (because they have been cast out of it and into the outer darkness), so therefore they must be outside of it. It's basic logic that doesn't register in the minds of many N.O. Catholics who don't dare question the multitude of heresies they've been fed by Vatican II.
With regards to the quote from Augustine, we see here how Augustine maintains that VII followers themselves tend to be manifest heretics. I've tried exposing the VII false religion to N.O. Catholics before, but they don't listen and use weak and ambiguous arguments to try and beat me down. They do not want to hold that Protestants are heretics because that is anti-(false)Ecuмenism. Sometimes, they even have the audacity to say that because the saints aren't infallible, we can just ignore them! How exceedingly pretentious.
Anyways.. You see, therefore, because they are obstinate in their heresies we cannot do anything but assume that they (many of them) are, in fact, heretics.
There are so many people who have more than what it takes to be elevated to sainthood when they die.. and yet they are held back and damned by heresies that they do not want to let go of.. It's very sad.. Pray for mother Church. :cry:
