The two periods in church history among those here named, which offer most instruction to us in consequence of affording examples of the same class of difficulties as those which we encounter, are, the struggle in the early centuries, and that in Germany during the present. The line of argument which was used in the former of these crises is seen in the Alexandrian school of the fathers in the third century, and that used in the latter, in the school of Schleiermacher. The study of the life and mental development of Schleiermacher’s disciple, Neander, would be in this view one of the most valuable in history.(1032) He was himself led by the mercy and providence of God to the knowledge of Christ; his own spirit was rescued from doubts such as we describe; his life was spent in trying to save others from the like difficulties, and to plant their feet upon the rock upon which he himself stood: and it is only the secrets of the great day that will declare the number of the souls that were led by his teaching to find Christ and salvation. In both these periods the method adopted for recommending Christianity was, to carry out the plan used by St. Paul at Athens,(1033) to lay a basis for the proof of it by developing the moral and philosophical argument. In the Alexandrian period the method used was, to show that all former religions, all former philosophies, were not unmixed error, but contained the germ of truth, which Christianity gathered into itself; to exhibit Christianity as the fulfilment in the field of history of the world’s yearnings, and thus to awaken the response of the heart to the narrative of its message.(1034) Reasons, to which allusion has before been made,(1035) may have lessened the utility at that period of the positive evidence, which proves the fact that a Redeemer had been given; but we cannot doubt that, independently of this circumstance, a deep philosophical reason suggested the stress which was laid on the moral argument, on account of its suitability for convincing the opponent;—a reason indeed to which the history of some of the fathers gave a personal force in the fact that it was by this manner that they had themselves been led to accept of Christianity.(1036)
