I can not believe God would condemn souls to damnation who never heard the Christian message. What does my Church say?
“Outside the Church there is no salvation”
This affirmation is not aimed at those who, through no fault of their own, do not know Christ and his Church:
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.
“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” (847-848).
Those also can attain to salvation who through no fault of their own do not know the gospel of Christ or his Church, yet sincerely seek God and moved by grace strive by their deeds to do his will as it is known to them through the dictates of conscience. Nor does Divine Providence deny the helps necessary for salvation to those who, without blame on their part, have not yet arrived at an explicit knowledge of God and with his grace strive to live a good life. Whatever good or truth is found amongst them is looked upon by the Church as a preparation for the gospel (16).
Pope Pius IX’s Quanto conficiamur moerore
There are, of course, those who are struggling with invincible ignorance about our most holy religion. Sincerely observing the natural law and its precepts inscribed by God on all hearts and ready to obey God, they live honest lives and are able to attain eternal life by the efficacious virtue of divine light and grace. Because God knows, searches and clearly understands the minds, hearts, thoughts, and nature of all, his supreme kindness and clemency do not permit anyone at all who is not guilty of deliberate sin to suffer eternal punishments (7).
Pope Pius IX’s Singulari Quadam (December 9, 1854):
It must, of course, be held as a matter of faith that outside the apostolic Roman Church no one can be saved, that the Church is the only ark of salvation, and that whoever does not enter it will perish in the flood. On the other hand, it must likewise be held as certain that those who live in ignorance of the true religion, if such ignorance be invincible, are not subject to any guilt in this matter before the eyes of the Lord. But then, who would dare to set limits to this ignorance, taking into consideration the natural differences of people, lands, native talents, and so many other factors?
