To the uncivilized tribes may be applied what has been said regarding the fate of unbaptized infants. The real problem is: How does the merciful Creator provide for those who are sufficiently intelligent to be able to speculate on God, the soul, the future destiny of man, etc.? Holy Scripture teaches: “Without faith it is impossible to please God, for he that cometh to God must believe that he is, and is a rewarder to them that seek him.”(558) Faith here means, not any kind of religious belief, but that theological faith which the Tridentine Council calls “the beginning, the foundation, and the root of all justification.”(559) Mere intellectual assent to the existence of God, immortality, and retribution would not be sufficient for salvation, even if elevated to the supernatural sphere and transfigured by grace. This is evident from the condemnation, by Pope Innocent XI, of the proposition that “Faith in a wide sense, based on the testimony of the created universe, or some other similar motive, is sufficient unto justification.”(560) The only sort of faith that results in justification, according to the Vatican Council, is “a supernatural virtue, whereby, inspired and assisted by the grace of God, we believe that the things which He has revealed are true; not because of the intrinsic truth of the things, viewed by the natural light of reason, but because of the authority of God Himself, who reveals them, and who can neither be deceived nor deceive.”(561) Of special importance is the following declaration by the same Council: “Since without faith it is impossible to please God and to attain to the fellowship of His children, therefore without faith no one has ever attained justification....”(562) The Catechism demands of every one who desires to be saved that he have a supernatural belief in six distinct truths: the existence of God, retribution in the next world, the Blessed Trinity, the Incarnation, the immortality of the soul, and the necessity of grace. The first two are certainly necessary for salvation, both _fide explicitâ_ and _necessitate medii_. With regard to the other four there is a difference of opinion among theologians. We base our argumentation on the stricter, though not absolutely certain view, that all six articles must be believed _necessitate medii_. On this basis God’s method of providing sufficient graces for the heathen may be explained in one of two ways, according as a _fides explicita_ is demanded from them with regard to all the above-mentioned dogmas, or a _fides implicita_ is deemed sufficient in regard to all but the first two. By _fides explicita_ we understand the express and fully developed faith of devout Christians; by _fides implicita_, an undeveloped belief of desire or, in other words, general readiness to believe whatever God has revealed.
