It is needful that the man who has to contend against all should have knowledge of the engines and the arts of all. He must be at once archer and slinger, commandant and officer, general and private soldier, foot-soldier and horseman, skilled in sea-fight and in siege. Unless he knows every trick and turn of war, the devil is well able, if only a single door be left open, to get in his ferocious bandits and to carry off the sheep." The sophisms of the enemy and the manifold strategy of his attack We have already touched upon. Let Us now say a word of advice on the means of defence. The first means is the study of Oriental languages and of the art of criticism. These two acquirements are in these days held in high estimation. The clergy, by making themselves more or less fully acquainted with them, as time and place may demand, will the better be able to discharge their office with becoming credit. They must make themselves "all things to all men," always "ready to satisfy every one that asketh them a reason for the hope that is in them." Hence it is most proper that professors of Sacred Scripture and theologians should master those tongues in which the Sacred Books were originally written. It would be well that Church students also should cultivate them, more especially those who aspire to academic degrees in Theology. Endeavors should be made to establish in all academic institutions--as has already been laudably done in many--chairs of the other ancient languages, especially the Semitic, and of subjects connected therewith, for the benefit principally of those who are destined to profess sacred literature. These latter, with a similar object in view, should make themselves well acquainted with and thoroughly exercised in the art of true criticism. There has arisen, to the great damage of religion, an artificial method, which is dignified by the name of the "higher criticism." It pretends to judge of the origin, the integrity, and the authority of every Book from internal indications alone. It is clear, on the other hand, that in historical questions, such as the origin and the handing down of writings, the witness of history is of primary importance, and that historical investigation should be made with the utmost care. In this matter internal evidence is seldom of great value, except by way of confirmation. To look upon it in any other light will be to open the door to many evil consequences. It will make the enemies of religion much more bold and confident in attacking and endeavoring to destroy the authenticity of the Sacred Books. This vaunted "higher criticism" will resolve itself into the reflection of the bias and the prejudice of the critics. It will not throw on the Scriptures the light which is sought, or prove of any advantage to doctrine. It will only give rise to disagreement and dissension, those sure notes of error, which the critics in question so plentifully exhibit in their own persons.
