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 many achieve eternal salvation.[19] Nor shall divine providence deny the assistance necessary for salvation to those who, without any fault of theirs, have not yet arrived at an explicit knowledge of God, and who, not without grace, strive to lead a good life. Whatever good or truth is found amongst them is considered by the Church to be a preparation for the Gospel[20] and given by him who enlightens all men that they may at length have life. But very often, deceived by the Evil One, men have become vain in their reasonings, have exchanged the truth of God for a lie and served the world rather than the Creator (cf. Rom. 1:21 and 25). Or else, living and dying in this world without God, they are exposed to ultimate despair. Hence to procure the glory of God and the salvation of all these, the Church, mindful of the Lord’s command, “preach the Gospel to every creature” (Mk. 16:16) takes zealous care to foster the missions.
