Are Only Catholics Saved?

On Invincible IgnoranceFr. Michael Müller, in perfect continuity with the most orthodox Catholic writers of the period, clarifies the teaching of Pope Piux IX by explaining that invincible ignorance neither saves nor condemns.
Testimony of the ScripturesArchbishop George Hay (1729 - 1811) succeeds, in a superb exegetical study of the scriptures, in examining what the Apostles taught concerning this key doctrine of our most holy religion. After a condemnation of those who hold to salvation outside the Church, the Archbishop reveals a wealth of scriptural quotes proving, beyond a doubt, that there is absolutely no salvation outside the bosom and unity of the Catholic Church.
Questions and Answers on SalvationThis is one of the most powerful additions ever to our website. As a sequal to the prolific Testimony of the Scriptures concerning the dogma "Outside the Church There is No Salvation", this "Q & A session" with the 18th century Archbishop George Hay clears up a great deal of "hazy points" regarding this doctrine. Everything from invincible ignorance, whether or not this doctrine is charitable, where the mercy of God comes in, etc., is covered in-depth in this article. This piece is destined to become a "classic" on the IHSV website. Answers all the questions!
Extra Ecclesiam Nulla SalusOrestes A. Brownson (1803-1876) does a masterful job in showing that only Catholics can be saved. It seems rather shocking to us that people in the 19th century denied this dogma, too. However, the undermining of this doctrine began germinating long before Brownson's time. We include this article in this list, not only because of the awesome truth it upholds, but also as a tribute to the man who held the Church's ground at a time when the clergy would not.
An ''Interview'' With the PopesIHSV "interviews" several popes (Pius IX, St. Pius X, etc.) and asks them questions regarding the solemn doctrine "Outside the Church there is no Salvation." We will get a front-seat view of what the popes really think regarding this doctrine. All the statements of the Pontiffs are taken from their own writings.
