Chapter 53.—The Utility of the Books of the Old Testament.

Under so great a weight of testimony, who would not be oppressed that should dare lift up his voice against the truth of God? And many other testimonies might be found, were it not for my anxiety to bring this tract to an end,—an anxiety which I must not slight. I have deemed it superfluous to quote from the books of the Old Testament, likewise, many attestations to our doctrine in inspired words, since what is concealed in them under the veil of earthly promises is clearly revealed in the preaching of the New Testament. Our Lord Himself briefly demonstrated and defined the use of the Old Testament writings, when He said that it was necessary that what had been written concerning Himself in the Law, and the Prophets, and the Psalms, should be fulfilled, and that this was that Christ must suffer, and rise from the dead the third day, and that repentance and remission of sins should be preached in His name among all nations, beginning at Jerusalem. In agreement with this is that statement of Peter which I have already quoted, how that all the prophets bear witness to Christ, that at His hands every one that believes in Him receives remission of his sins.
