I think you have a valid point here. I hope the Pope addresses this in the near future. It has implications for ecumenism and it has implications in terms of our zeal, or lack of zeal, to help save souls.
I think you are referring to the heresy of indifferentism?
If you carefully examine the means used by liberals (wittingly or unwittingly) to undermine the truths of the faith, it is usually through an exadurated emphasis on the exception to the exclusion and eventual denial of the rule.
Some people are so lost in doctrinal indifferentism that you can only make the point with them by drawing a parallel with a moral issue, which I will now do…
Here is an example of how the teaching of the use of birth control could be watered down. First let me state a few facts
Believe it or not, the Church does allow the use of birth control. Did you know that? It is true. It is allowed when the motive is not to prevent birth, but for another medical reason. I forget ther term. I think it is madicinal, or therapudic, or somthing. Humana Vitea discusses this “exception” to the rule.
It is also be true to say that, due to invincible ignorance, not every person who uses birth control is guilty of a mortal sin. If they honestly don’t know the truth, and if their ignorance is truly invincible (due to no fault of their own), then they would not be guilty of a mortal sin. And it may even be true that a whole lot of Catholics today who use birth control are not guilty of a mortal sin. In fact, they are probably not even guilty of any subjective sin.
Therefore, realizing these two facts (both of which are true), what if Catholics were continously told that birth control is not always forbidden by the Church, and even when it is forbidden it is not always sinful. And what would the result be if this was all that Catholic heard for 40 years?
I will tell you what the result would be: It would result in Catholics thinking that the Church has changed its teaching on the use of birth control, and that is is no longer fobidden. That would be the result. They would eventually claim that birth control is allowed by the Church, which is a statement that has some truth to it, but is very misleading.
And that is exactly what has happened with the dogma in question. It has been so watered down that now just about everyone is considered “invincibly ignorant” - even those who have explicitly rejected the Catholic Church.
The final result is that many Catholics today reject the dogma outside the Church there is no salvation - a dogma that they are required to believe to remain in the state of grace.
Pope Pius IX (A.D. 1846 - 1878): “It must be held **by faith **that outside the Apostolic Roman Church, no one can be saved; that this is the only ark of salvation; that he who shall not have entered therein will perish in the flood.” (Denzinger 1647)
Most Catholics today have fallen into the following error addressed by Pope Pius XII in 1950
Pope Pius XII (Humani Generis): “Some say they are not bound by the doctrine, explained in Our Encyclical Letter of a few years ago, and based on the Sources of Revelation, which teaches that the Mystical Body of Christ and the Roman Catholic Church are one and the
same thing. Some reduce to a meaningless formula the necessity of belonging to the true Church in order to gain eternal salvation.”
