No less erroneous is the Catholic argument for the uninterrupted continuation of the church of Christ on earth, based on the passage in the sixteenth chapter of Matthew, when Jesus in the course of a conversation with Peter says to him: "Thou art Peter, and upon this rock I will build my church, and the gates of hell shall not prevail against it." "By this promise," says a foot-note on this passage in the Douay Bible--the version accepted by the Catholic Church,--"we are fully assured that neither idolatry, heresy, nor any pernicious error whatever, shall at any time prevail over the church of Christ." "Our blessed Lord clearly intimates here," says Cardinal Gibbons, "that the church is destined to be assailed always but to be overcome never." [6] The argument of Catholics is, that if the great apostasy took place which, as we have seen, is clearly predicted in the scriptures, and, as I believe, confirmed by the facts already presented to the reader in this volume, then the express promise of Jesus Christ that the gates of hell should not prevail against His church has failed. "If the prediction of our Savior about the preservation of His church from error be false, then Jesus Christ is not God, since God cannot lie. He is not even a prophet, since he predicted falsehood. Nay, he is an imposter, and all Christianity is a miserable failure, and a huge deception, since it rests on a false prophet." [7] This argument and its conclusion is based upon too narrow a conception of the Church of Christ. That church exists not only on earth, but in heaven; not only in time, but in eternity. It has not been prevailed against, because men on earth have departed from it; corrupted its doctrines, changed its ordinances, transgressed its laws. The Church of Christ in heaven, consisting of "an innumerable company of angels--the general assembly and church of the firstborn, which are written in heaven--" [8] the church there has been far beyond the reach of the powers of hell; and ultimately here on earth it shall be triumphant. To repeat an illustration I before used: Truth may lose a single battle, it may lose two or three, and yet be victorious in the war. So with the Church of Christ: many of those enrolled as its members may be stricken down by cruel persecution; those remaining may capitulate with the enemy, and by compromises betray the cause of Christ, and put him to an open shame. Repose and luxury, the reward of the above perfidy, may bring in such floods of wickedness that virtue can scarce be found among men, and no abiding place found on earth for the church of the Redeemer. That church, however, still exists in heaven, in all the glory of the general assembly of the firstborn; and from time to time dispensation after dispensation of the gospel will be sent from thence to the children of men, until a people shall be found who will remain true to all its doctrines, accept its ordinances, obey its precepts,
