So the truths of religious faith, separated from the source of faith, lose their vitality; and to a reflecting man who asks himself why he believes them, they will soon appear no longer true, because he has no longer any faith in the original authority which is the witness of God for them before the world. For it should be self-evident to every one of the least intelligence, that religious truth concerning man's future destiny in an eternity which no man living has ever seen cannot possibly depend upon one's experience or study in this world, and that the mysterious doctrines of Christianity can only appear true to a man on sufficient authority, and that, too, a living, present authority, which is a witness to him as well as to his forefathers. Hence the necessity of an ever-present, living source of faith, and the equal necessity of an actual union with it, in order to have faith in the doctrines of Christianity at all. But the present position of our American Protestant brethren seems to be at variance with this; for we see them having a good, sincere faith in many of the revealed doctrines of Christianity, and yet are cut off from the living source of faith, which we know to be the infallible and divine voice of the church. And not only cut off, but they reject that source altogether, deny its authority, and look upon it rather as the source of falsehood than of truth. But, when we examine the matter closely, we shall see that they do not deny that they have a real source of their faith, or that such source is the church of Christ--which they suppose their own to be--only that they are ignorant of the fact that the Catholic Church is the church of Christ, and that she is the true source of their faith, and, if that church was destroyed and its authority nullified, they could have no faith at all. When they have lost all faith and obedience to a church which they regard as the church of Christ, and have not returned to Catholicity, they have lost at the same time all faith in the peculiar doctrines of Christianity. It would be hardly worth while to consider the answer made by some that they believe in Christ on no church authority, but on the authority of the Bible alone, because it is plain that one must first know the Bible itself to be true on some authority and surely the authority of the type-setter, the printer, and the paper-maker would not be sufficient, and the only authority they have or can have of its truth is that of the Christian church, which sets its seal upon it, and declares it to be the Word of God. {134} There is no doubt that they are cut off from all real church authority, that their religion is a separated branch from the living tree: and the state of things is such as we would expect to happen; the branch will wither, they will lose faith in Christ and his doctrines, and they are deprived of all those inestimable blessings and privileges which can only be had in union with the true and living church.
