      Q. 200. Give an example of truths which all believe, though many do not understand them. A. All believe that the earth is round and moving, though many do not understand it. All believe that a seed planted in the ground will produce a flower or tree often with more than a thousand other seeds equal to itself, though many cannot understand how this is done.

      Q. 201. Why must a divine religion have mysteries? A. A divine religion must have mysteries because it must have supernatural truths and God Himself must teach them. A religion that has only natural truths, such as man can know by reason alone, fully understand and teach, is only a human religion.
