He is the second Adam, who came to undo the work of the first Adam; and as the terrible consequences of the first transgression have extended to _all_ men without exception, so, also, to repair this evil which has come upon all men it was necessary that the grace of salvation should be offered to _all_ without exception. And from this we may infer that God does not simply will that men should be saved, but that he actually gives to every man that is born sufficient grace to accomplish this great work. But are those who stay outside of the one fold in the way to use this sufficient grace? Certainly they are not, or our Lord never would have said: "Them also I must bring, and they shall hear my voice, and there shall be one fold and one shepherd." No one, therefore, can be said to be in the way of salvation who stays outside of the one true fold of the Catholic Church. We cannot, of course, know what extraordinary means of grace God may use for those who are ignorant of the church, yet we do know with perfect certainty that the Catholic Church, with its doctrine, sacraments, and other means of grace, is the only divinely-established means of salvation for all men. Knowing, then, that our Divine Lord, inasmuch as he died for all men, wills to bring all men into the one true fold, where they may be under one shepherd, we must feel it to be our duty, if we have the love of Christ in our hearts, by our prayers, words, and good example to bring the "other sheep" of whom our Lord speaks so lovingly to the knowledge of this one fold. {229} It is only a coldness of faith and charity which can make us look upon those who are outside of the church as if they were already where they ought to be, and where God wishes them to be, or make us think that it is a hopeless task to try to bring them into the true church. Our Lord has promised that they shall hear his voice. We know, then, that he will co-operate by his all-powerful grace with what we do for their salvation.
