The teaching of this encyclical is parallel with that of the allocution Singulari Quadam. In both of these docuмents Pope Pius IX insisted upon the fact that it is a dogma of the faith that no man can be saved outside the Catholic Church. Indeed, the language of the encyclical on this point is even more forceful and explicit than that of the allocution. Likewise in both of these docuмents there is a very clear implication of the truth that a man can be "within" the true Church in such a way as to be saved without being a member of this society and, indeed, without having a explicit knowledge of it at all. Moreover both the Quanto Conficiamur Moerore and the Singulari Quadaminsist upon the missionary nature of the Church and bring this truth into play in their explanations of the dogma. The encyclical, however, brings out some aspects of the teaching not touched upon directly in the allocution which was delivered almost nine years previously. The following two paragraphs of the Quanto Conficiamur Moerorehave to do with the dogma of the Church's necessity for salvation. Fenton

There are three most important lessons contained in this section of the Quanto Conficiamur Moerore, the Holy Father's insistence upon the real necessity of the Church for salvation, his implied indication of a distinction between the necessity of means and the necessity of precept, and his teaching about the possibility of salvation for a man who is invincibly ignorant of the true religion but who faithfully observes the natural law. All of these lessons must be studied carefully by a man who seeks to know the genuine doctrine of the Catholic Church on the necessity of the Church for the attainment of eternal salvation. The teaching of the Quanto Conficiamur Moerore has a special importance because this encyclical has been misinterpreted more than once by men who offered inadequate or inaccurate explanations of the dogma that there is no salvation outside the Church.

I have just about made up my mind to start a new book. I shall write on the notion of the Church. Nothing like this has appeared since the Council. Within the book I hope to have quite a bit to say about the Council. I must be very careful. If a sincere Catholic writes a book it’s either ignored or brutally attacked. I must make no mistakes. My main thesis will have to be that the Catholic theology on the Church has been improved but in no way changed by the Council.

Hence, when true Catholic charity takes care of a man who is sick or afflicted in any other way, it does not look upon this man as one whose destiny is limited to this world and to this life. On the contrary, it takes explicit cognizance that the person it works to benefit is one for whom Our Lord died on the Cross, one whom God wills to have with Him forever in the glory of the Beatific Vision. In the encyclical Quanto Conficiamur Moerore, Pope Pius IX reminded the Catholics of the entire world that this explicit cognizance should be eminently practical. The work of the Catholic charity is definitely not complete unless every effort has been expended to free men from the errors that keep them from the eternal possession of God which is their only ultimate end. And, since, by God's own institution, the true Church of Jesus Christ is really requisite for the attainment of man's eternal and supernatural salvation, the work of Catholic charity is lamentably incomplete unless every reasonable effort has been made to persuade non-Catholics to enter this society.
