The most Holy Roman Church firmly believes, professes and preaches that none of those existing outside the Catholic Church, not only pagans, but also Jews and heretics and schismatics, can have a share in life eternal; but that they will go into the eternal fire which was prepared for the devil and his Angels, unless before death they are joined with Her; and that so important is the unity of this ecclesiastical body that only those remaining within this unity can profit by the Sacraments of the Church unto salvation, and they alone can receive an eternal recompense for their fasts, their almsgivings, their other works of Christian piety and the duties of a Christian soldier. No one, let his almsgiving be as great as it may, no one, even if he pour out his blood for the Name of Christ, can be saved, unless he remain within the bosom and the unity of the Catholic Church.
Pope Eugene IV, Cantate Domino, 1441 (Council of Florence)
You [Eugenio Scalfari] ask if the God of the Christians forgives those who do not believe and do not seek faith. Given that—and this is fundamental—God's mercy has no limits if he who asks for mercy does so in contrition and with a sincere heart, the issue for those who do not believe in God is in obeying their own conscience. In fact, listening and obeying it, means deciding about what is perceived to be good or to be evil. The goodness or the wickedness of our behavior depends on this decision.
Pope Francis, Letter to Eugenio Scalfari, 2013
“And I repeat it here. Everyone has his own idea of good and evil and must choose to follow the good and fight evil as he conceives them. That would be enough to make the world a better place.”
