Our Refuge, invincible ignorance does not save a man. Pope Pius IX never once said in his encyclicals (which BTW are fallible, not dogmatic) that a man is saved by being ignorant of the Truth? He states that a mans’ invincible ignorance of the Truth will not condemn him for the sin of infidelity, which is the sin of hearing the Word of God, and rejecting the Truth,(not believing) but he never says it will save him either. On the contrary Pope Pius IX states most
emphatically that no one is saved outside the Catholic Church.
Singulari Quadem, 1854: For, 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; but, on the other hand, it is necessary to hold for certain that they who labor in ignorance of the true religion, if this ignorance is invincible, are not stained by any guilt in this matter in the eyes of God. The guilt of infidelity. One must die in sanctifying grace in order to be saved. Here is what St. Thomas Aquinas states: St. Thomas Aquinas, Summa II-II, Q.10 art. 1, I answer that: “Infidels of this sort are not damned for the sin of infidelity, but are indeed damned for other sins which cannot be remitted without faith. Wherefore, the Lord says: ‘If I had not come and spoken to them, they would not have sin’ (John 15:22); that is, as St. Augustine explains it, ‘they would not have the sin of not believing in Christ.’”
Pope Pius IX further teaches that a man who is of good will, is sincerely seeking the truth will not be left unaided.
Pope Pius IX, Singulari Quadem, 1854: But, just as the way of charity demands, let us pour forth continual prayers that all nations everywhere may be converted to Christ; and let us be devoted to the common salvation of men in proportion to our strength, ‘for the hand of the Lord is not shortened’ (Isa. 9:1) and the gifts of heavenly grace will not be wanting those who sincerely wish and ask to be refreshed by this light. Truths of this sort should be deeply fixed in the minds of the faithful.
Also

ope Pius IX, Singulari Quadem, 1854: Nothing more excellent has been given by the providence of God to man than the authority of divine faith; that this is for us, as it were, a torch in the darkness, a guide which we follow to life; that this is absolutely necessary for salvation; for, ‘without faith… it is impossible to please God’ [Heb. 11:6] and ‘he that believeth not, shall be condemned’ [Mk. 16:1]
Pope Pius IX, Singulari Quadem, 1854: Not without sorrow we have learned that another error, no less destructive, has taken possession of some parts of the Catholic world, and had taken up its abode in the souls of many Catholics who think that one should have good hope of eternal salvation of all those who have never lived in the true Church of Christ. Therefore they are wont to ask very often what will be the lot and condition after death of those who have not submitted in any way to the Catholic faith, and by bringing forward most vain reasons, they make a response favorable to their false opinion. …the gifts of heavenly grace will not be wanting those who sincerely wish and ask to be refreshed by this light. Truths of this sort should be deeply fixed in the minds of the faithful, lest they be corrupted by false doctrines, whose object is to foster an indifference toward religion, which we see spreading widely and growing strong for the destruction of souls… let us hold most firmly that, in accordance with Catholic teaching, there is “one God, one faith, one baptism” (Eph. 4:5); it is unlawful to proceed further in inquiry.
And it is dogma that all who die with the guilt of original sin descend immediatley to hell. It was infallibly defined A.D. 418
at the Council of Carthage.
Pope St. Zosimus, Council of Carthage XVI, Original Sin and Grace, 418: “Canon 3. It has been decided likewise that if anyone says that for this reason the Lord said: ‘In my Father’s house there are many mansions’ [John 14:2]: that it might be understood that in the kingdom of heaven there will be some middle place or some place anywhere else where blessed [beati] infants live who departed from this life without baptism, without which they cannot enter into the kingdom of heaven, which is life eternal, let him be anathema. For when the Lord says: ‘Unless a man be born again of water and the Holy Ghost, he shall not enter into the kingdom of God’ (Jn. 3:5), what Catholic will doubt that he will be a partner of the devil who has not deserved to be a coheir of Christ? For he who lacks the right part will without doubt run to the left.” (Denzinger)
The dogma that those who die with the sole guilt of original sin are punished and the dogma that they are punished less than those who die with the guilt of mortal sin were infallibly defined in A.D. 1274 at the Second Council of Lyons and again in A.D. 1439 at the Council of Florence:
Pope Gregory X, Second Council of Lyons, 1274: “The souls of those who die in mortal sin or only with original sin go down into hell, but there they receive unequal [disparibus] punishments.”[6]
Pope Eugene IV, Council of Florence, 1439: “The souls of those who depart in actual mortal sin or in original sin only, descend immediately into hell but to undergo punishments of unequal [disparibus] kinds.”
It is the enemies of the Catholic Church, the Catholic Faith who either out and reject the dogma’s of the Catholic Church, or water them down to render them meaningless; particularily the dogma EENS. Again recite the dogmatic creed (all Catholc Creed’s are dogmatic) Athansian Creed. Whosoever will be saved, before all things it is necessary that he hold the catholic faith;
- Which faith except every one do keep whole and undefiled, without doubt he shall perish everlasting. I hope this is helpful to you.
