I agree with this as far as it goes. Just want to add, that most Protestants would approach this from a different perspective. They see “the Church” as a collection of individuals; they might notice that in a given country, or in a given decade, it appears that Protestant individuals know more about God on average than Catholic individuals, just as Protestants on average may be holier. And they may right at times, from their view.
But Catholics view “The Church” as something in itself. The Church is wise, the best source of all knowable knowledge, even if all Catholics are fools this month. The Church is holy, the best available human channel of God’s grace, even if all Catholics that year are scoundrels, and all Protestants are devout and prayerful.
Heaven and Hell are populated by individuals, not denominations. When I go before St. Peter, it won’t help my case to claim “I had the best opportunities for doctrine and sanctity”. So?
