it as a book known to His hearers, His reference lies as wholly outside all questions of genuineness and authenticity as does St. Jude's quotation from the Book of Enoch, or St. Paul's (possible) allusions to the Assumption of Elijah,[202] or Christ's own passing reference to the Book of Jonah. Those who attempt to drag in these allusions as decisive critical dicta transfer them to a sphere wholly different from that of the moral application for which they were intended. They not only open vast and indistinct questions as to the self-imposed limitations of our Lord's human knowledge as part of His own voluntary "emptying Himself of His glory," but they also do a deadly disservice to the most essential cause of Christianity.[203] The only thing which is acceptable to the God of truth is truth; and since He has given us our reason and our conscience as lights which light every man who is born into the world, we must walk by these lights in all questions which belong to these domains. History, literature and criticism, and the interpretation of human language do belong to the domain of pure reason; and we must not be bribed by the misapplication of hypothetical exegesis to give them up for the support of traditional views which advancing knowledge no longer suffers us to maintain. It may be true or not that our Lord adopted the title "Son of Man" (_Bar Enosh_) from the Book of Daniel; but even if He did, which is at least disputable, that would only show, what we all already admit, that in His time the Book was an acknowledged part of the Canon. On the other hand, if our Lord and His Apostles regarded the Book of Daniel as containing the most explicit prophecies of Himself and of His kingdom, why did they never appeal or even allude to it to prove that He was the promised Messiah? Again, Hengstenberg and his school try to prove that the Book of Daniel existed before the Maccabean age, because Josephus says that the high priest Jaddua showed to Alexander the Great, in the year B.C. 332, the prophecy of himself as the Grecian he-goat in the Book of Daniel; and that the leniency which Alexander showed towards the Jews was due to the favourable impression thus produced.[204] The story, which is a beautiful and an interesting one, runs as follows:--
