From what I can gather, the current church doesn’t think being Protestant will damn someone’s soul. Was this the case prior to Vatican II? Why was the church in earlier centuries so against Protestantism and seeing them as going to Hell? If the church can’t be in error and the pope is infallible, how can the church have made changes? Did Vatican II in fact change this centuries old belief about non Catholics?
There are a few misunderstandings in your statement that are probably leading to your confusion. First is the nature of the pope’s infallibility, and don’t worry, this is one of the most commonly misunderstood aspects of the Catholic Church. The pope is not infallible everywhere, all the time, about everything. If he was, then how would the corrupt popes of the Middle Ages be explained? The pope is only infallible when he speaks “ex cathedra”, meaning that he is speaking on behalf of the church to give a declaration about a specific doctrine which has been brought into question. To date, the pope has officially used this power only twice (defining the Immaculate Conception and the Assumption of Mary). Ecumenical Councils and the Magesterium of the Church also have versions of infallibility as well. Most doctrines are never defined, and as such, are still open to interpretation.
Second, the teaching about Protestants has never changed. Catholics believe that
anyone can be saved, even non-Christians, but that the further away your beliefs are from Catholicism, the increasingly difficult it becomes.
Here is the quote from the Catechism:
“Outside the Church there is no salvation”
846 How are we to understand this affirmation, often repeated by the Church Fathers? Re-formulated positively, it means that all salvation comes from Christ the Head through the Church which is his Body:
Code:
Basing itself on Scripture and Tradition, the Council teaches that the Church, a pilgrim now on earth, is necessary for salvation: the one Christ is the mediator and the way of salvation; he is present to us in his body which is the Church. He himself explicitly asserted the necessity of faith and Baptism, and thereby affirmed at the same time the necessity of the Church which men enter through Baptism as through a door. Hence they could not be saved who, knowing that the Catholic Church was founded as necessary by God through Christ, would refuse either to enter it or to remain in it.
847 This affirmation is not aimed at those who, through no fault of their own, do not know Christ and his Church:
Code:
Those who, through no fault of their own, do not know the Gospel of Christ or his Church, but who nevertheless seek God with a sincere heart, and, moved by grace, try in their actions to do his will as they know it through the dictates of their conscience - those too may achieve eternal salvation.
848 “Although in ways known to himself God can lead those who, through no fault of their own, are ignorant of the Gospel, to that faith without which it is impossible to please him, the Church still has the obligation and also the sacred right to evangelize all men.”
In short, if through no fault of your own you are not Catholic, and lived a good life that would have been in line with Catholic teachings, you could still get to heaven. But… without knowing what the prerequisites were, it would be harder to know what the moral way to live was, and so it would be much more difficult to be saved. If you are a good Protestant and don’t join Catholicism out of ignorance of the truth of its doctrine, then you still have a chance for salvation. If, however, you ARE Catholic and turn from Catholic teachings to become another denomination, or if you are Protestant and recognize the truth of the Catholic Church and refuse to join,
then you would be doomed to hell because you are turning from the true teachings. This has always held true, but realize during the Protestant Reformation, most people HAD been Catholic, and were turning from the Catholic Church to other denominations. Today, the majority of Protestants are already Protestant.
Also note that the Catechism says that “There is no salvation outside of the Church”. It goes on to say that all salvation comes from Christ the Head through the Church which is his Body. In other words, anyone who is saved is saved because of the Catholic Church, whether they know it or not. Even if they weren’t Catholic, they were saved because their actions during their life matched and were in line with Catholic teaching, which has the guarantee of protection by the Holy Spirit.
