But though every created thing is, in this sense, a mystery, the word mystery cannot be applied to moral truth, any more than obscurity can be applied to light. The God in whom we believe is a God of moral truth, and not a God of mystery or obscurity. Mystery is the antagonist of truth. It is a fog of human invention that obscures truth, and represents it in distortion. Truth never envelops itself in mystery; and the mystery in which it is at any time enveloped, is the work of its antagonist, and never of itself. Religion, therefore, being the belief of a God, and the practice of moral truth, cannot have connection with mystery. The belief of a God, so far from having any thing of mystery in it, is of all beliefs the most easy, because it arises to us, as is before observed, out of necessity. And the practice of moral truth, or, in other words, a practical imitation of the moral goodness of God, is no other than our acting towards each other as he acts benignly towards all. We cannot serve God in the manner we serve those who cannot do without such service; and, therefore, the only idea we can have of serving God, is that of contributing to the happiness of the living creation that God has made. This cannot be done by retiring ourselves from the society of the world, and spending a recluse life in selfish devotion. The very nature and design of religion, if I may so express it, prove even to demonstration that it must be free from every thing of mystery, and unincumbered with every thing that is mysterious. Religion, considered as a duty, is incumbent upon every living soul alike, and, therefore, must be on a level to the understanding and comprehension of all. Man does not learn religion as he learns the secrets and mysteries of a trade. He learns the theory of religion by reflection. It arises out of the action of his own mind upon the things which he sees, or upon what he may happen to hear or to read, and the practice joins itself thereto. When men, whether from policy or pious fraud, set up systems of religion incompatible with the word or works of God in the creation, and not only above but repugnant to human comprehension, they were under the necessity of inventing or adopting a word that should serve as a bar to all questions, inquiries and speculations. The word mystery answered this purpose, and thus it has happened that religion, which is in itself without mystery, has been corrupted into a fog of mysteries. As mystery answered all general purposes, miracle followed as an occasional auxiliary. The former served to bewilder the mind, the latter to puzzle the senses. The one was the lingo, the other the legerdemain. But before going further into this subject, it will be proper to inquire what is to be understood by a miracle.
