Jimmy Akin: Are most Catholics in America going to hell?
From the private interpretation of one of Rome's apologists:
How Many People Go To Hell?
We can’t really know this.
Different figures in Church history have had different viewpoints on the question, and the Church itself does not have a teaching on the matter.
Some passages of Scripture seem to have a pessimistic tone but others seem to have an optimistic tone. We also should be careful in taking the pessimistic ones and applying them directly to our own age, because they were written in and about an age in which the world was swallowed in pagan darkness and the knowledge of the true God and his Son was severely limited compared to today. For its part, the Church teaches the real possibility of dying in mortal sin and of eternal damnation, but it does not teach how many people experience this in practice.
“Let nobody suppose that he has tasted the Holy Scriptures sufficiently unless he has ruled over the churches with the prophets for a hundred years. Therefore there is something wonderful, first, about John the Baptist; second, about Christ; third, about the apostles...“We are beggars. That is true.” - Martin Luther
"It is true that the best apologetics can be given only when the system of truth is well known. But it is also true that the system of truth is not well known except it be seen in its opposition to error."- Cornelius Van Til
"But a most pernicious error widely prevails that Scripture has only so much weight as is conceded to it by the consent of the church. As if the eternal and inviolable truth of God depended upon the decision of men!"- John Calvin
This is the best book available on Sola Scriptura. For Protestants, it will help you understand and defend sola scriptura. For Catholics, this book will help you understand exactly what Protestants mean by sola scriptura, rather than what you think it means. I highly recommend getting this book, it never leaves my desk, and serves as a valuable reference tool.
