This is eminently true of the Bible as a text or guide in the acquisition of the highest of arts, the profoundest of sciences, which leads us to the recognition of absolute truth, with an ever-increasing apprehension, because its scope is immeasurable, eternal. The teacher of revelation, in its first and most important signification, is Christ. He is the central historical figure, announced to man immediately after his fall in Paradise foreshadowed by the prophets in the Jewish Church, and completing His mission in the Christian Church. As the Holy Ghost animated the prophets to foretell Him, and the priests of the synagogue to announce Him in the Old Law, so the Holy Ghost animates the Church to continue His work in the New Law. As books were written by the prophets of old to perpetuate the remembrance of what Jehovah had spoken through them to His people regarding the coming of the Messias, so books were written by the Apostles and disciples of the New Law to perpetuate the remembrance of what that Messias had said and done, and of what He wished us to do. But as the old written Law was not to be a substitute for the commission of teaching and guiding the people through the Jewish Synagogue, so neither was the new written Law intended to be a substitute for the commission of teaching and guiding those who seek salvation through Christ. The Bible alone, as we have already seen, cannot satisfy us in such a way as to supply the full reason for our faith in Christ's teaching. For this we have a Church to whom Christ, as God, gave a direct commission, without adding a book, or an express command to write a book. But a book was written, written under the guidance of the divine Spirit, who had been promised to the Church whenever it would speak, whether by word of mouth or by epistle and written gospel. And that book, though not containing all truth, contains truth only. Therefore it is useful, as St. Paul says, II. Tim. iii. 16: "All Scripture inspired of God is profitable to teach, to reprove, to correct, to instruct in justice, that the man of God may be perfect, furnished to every good work." The use, then, of the Bible is to teach, to instruct in justice, primarily; to make man perfect, furnished to every good work. Mark the twofold term: to _teach_ and to _instruct_; both teaching and instruction to serve the one end--to make a perfect man, "furnished to every good work."
