And so it is with worship. We fetter and cramp our thoughts of deity when we bind them to even the loftiest conceptions which have ever been shut up in marble or upon canvas. The best image that ever took shape is inferior to the poorest spiritual conception of God, in this respect if in no other—that it has no expansiveness, it cannot grow. And in connecting our prayers with it, we virtually say, ‘This satisfies my conception of God.’ It is not to be condemned merely as inadequate, for so are all our highest thoughts of deity; nor only because average humanity (which is supposed to stand most in need of the help and suggestion of art) will never learn the fine distinctions by which subtle intellects withhold from the image itself the worship which it evokes, and which goes out in its direction. It is still more mischievous because, even for the trained theologian, it is the petrifaction of what is meant to develop and expand, the solidification of the inadequate, the accepting of what is human as our idea of the divine. Nor will it long continue to be merely inadequate. Experience proves that ideas, like air and water, cannot be confined without stagnating. Idolatries not only fail to develop, they degenerate; and systems, however orthodox they may appear at starting, which connect worship with palpable imagery, are doomed to sink into superstition. To this precept there is added a startling and painful caution—“For I the Lord thy God am a jealous God.” That a man should be jealous is no passport to our friendship: we think of unreasonable estrangements, exaggerated demands, implacable and cruel resentments. It would not enter the average mind to doubt that one is highly praised when another says of him, ‘I never traced in his words or actions the slightest stain of jealousy.’ And yet we are to think of God Himself as the jealous God.
