Here St. Peter directs us back to the Holy Scriptures, that we may therein see that God keeps whomsoever He has called of us, for no merit of ours, but of mere grace; for the whole of Scripture is directed to this end, that it may draw us away from our own works and bring us to faith. And it is necessary that we should study the Scriptures carefully that we may be well assured of our faith. Paul also teaches us the same thing in the Epistle to the Romans, chap. i., where he says that God promised the Gospel before by His prophets in the Holy Scriptures. So Rom. iii.: that the faith whereby we are justified, is testified of through the law and the prophets. So we read also in Acts xvii. how Paul preached faith to the Thessalonians, leading them to the Scripture and explaining it to them, and how day by day they had recourse to the Scripture, and examined whether those things which Paul had taught them were so. So likewise ought we to do, going back, and from the Old Testament learning on what to base the New. Besides, we shall there discover the promise of Christ, as Christ himself also says, John v.: "Search the Scriptures, for it is they that testify of me." And "if ye believe Moses, ye must also believe me, for he wrote of me." Therefore we should let vain babblers go who despise the Old Testament, and say it is of no further use,--since from thence alone must we derive the ground of our faith; for God sent the Prophets to the Jews to this end, that they should bear witness of the Christ that was to come. Therefore it is that the Apostles throughout convicted and convinced the Jews out of their own Scriptures that this was the Christ. Thus the books of Moses and the prophets are the Gospel, since they have first preached and written of Christ that which the Apostles afterward preached and wrote. Yet there is a distinction between them. For although both, as to the letter, have been written out on paper, yet the Gospel, or the New Testament, cannot be said so properly to be written, but to have consisted in the living voice which published it, and was heard generally throughout the world. But that it should also have been written, is an extraneous matter. But the Old Testament was composed only in writing, and is therefore called the letter; and the Apostles give Scripture this same name also, as it only pointed to the Christ that was to come. But the Gospel is a living proclamation of Christ who has already come.
