The history of these names illustrates yet another phenomenon. In some narrow and imperfect sense the early Semitic peoples seem to have called God “Father” and “Brother.” Because the terms were limited to a narrow sense, the Israelites grew to a level of religious truth at which they could no longer use them; but as they made yet further progress they came to know more of what was meant by fatherhood and brotherhood, and gained also a deeper knowledge of God. At length the Church resumed these ancient Semitic terms; and Christians call God “Abba, Father,” and speak of the Eternal Son as their elder Brother. And thus sometimes, but not always, an antique phrase may for a time seem unsuitable and misleading, and then again may prove to be the best expression for the newest and fullest truth. Our criticism of a religious formula may simply reveal our failure to grasp the wealth of meaning which its words and symbols can contain. Turning from these obsolete names to those in common use—_El_; _Jehovah_; _Shaddai_; _Zur_; _Melech_—probably the prevailing idea popularly associated with them all was that of strength: _El_, strength in the abstract; _Jehovah_, strength shown in permanence and independence; _Shaddai_, the strength that causes terror, the Almighty from whom cometh destruction(56); _Zur_, rock, the material symbol of strength, _Melech_, king, the possessor of authority. In early times the first and most essential attribute of Deity is power, but with this idea of strength a certain attribute of beneficence is soon associated. The strong God is the Ally of His people; His permanence is the guarantee of their national existence; He destroys their enemies. The rock is a place of refuge; and, again, Jehovah’s people may rejoice in the shadow of a great rock in a weary land. The King leads them to battle, and gives them their enemies for a spoil. We must not, however, suppose that pious Israelites would consciously and systematically discriminate between these names, any more than ordinary Christians do between God, Lord, Father, Christ, Saviour, Jesus. Their usage would be governed by changing currents of sentiment very difficult to understand and explain after the lapse of thousands of years. In the year A.D. 3000, for instance, it will be difficult for the historian of dogmatics to explain accurately why some nineteenth-century Christians preferred to speak of “dear Jesus” and others of “the Christ.”
