So here's his final argument.
As an aside, he keeps interjecting this very diabolical-sounding voice grumbling "Tradcast" between the various sections of audio.
If someone is baptized as an infant, even if in a Protestant sect, then the person enters a state of sanctifying grace. But the only way to lose sanctifying grace is to commit a mortal sin. So if this person grows up a Protestant but never pretinaciously embraces heresy, then the person remains in a state of grace. But since the person does not profess the true faith, he's not a member of the Church. So therefore it's possible for a person who's not a member of the Church to be in a state of sanctifying grace.
That's completely false, for the infused supernatural faith and charity must be accompanied and affirmed by the proper dispositions for Baptism once the person reaches the age of reason. Take the case, for instance, of someone who is baptized as an infant but then is raised by animists. That supernatural faith ceases by simple privation, due to lack of faith, even if there's no conscious sin against the faith, due to atrophy and the lack of conscious acceptance.
If, on the other hand, you do find someone among the Protestants, especially a young person, who happens to have so rudimentary and ichoate a state of faith that he still he actively embraces the faith with the necessary supernatural and infallible formal motive of faith, that person is a CATHOLIC who's simply in purely material heresy and no more ceases to profess the faith than any other CATHOLIC who has fallen into material heresy.
In addition, the profession of true faith is not a required condition of membership absolutely, for those below the age of reason do not profess the true faith but nevertheless they are full members of the Church.
So epic fail again.
And again it's quite sickening to see someone spend 26 minutes out of 30 explaining away EENS in an alleged attempt to explain it.
In the final analysis, then, he should have zero problems with Vatican II becomes he claims that Protestants and other non-Catholics can be within the Church (which is V2 subsistence ecclesiology).
