Yet apply impartially to both sets the test, not of form, but of content, of spiritual fruitfulness and of many-sided applicability--and this surface-similarity yields at once to a fundamental difference. Indeed all the great mystics, and this in precise proportion to their greatness, have ever taught that, the mystical capacities and habits being but means and not ends, only such ecstasies are valuable as leave the soul, and the very body as its instrument, strengthened and improved; and that visions and voices are to be accepted by the mind only in proportion as they convey some spiritual truth of importance to it or to others, and as they actually help it to become more humble, true, and loving. And there can be no doubt that these things worked thus with such great ecstatic mystics as Ezekiel, the man of the great prophetic schemes and the permanently fruitful picturing of the Good Shepherd; as St. Paul, the greatest missionary and organizer ever given to the Christian Church; as St. Francis of Assisi, the salt and leaven and light of the Church and of society, in his day and more or less ever since; as St. Catherine of Siena, the free-spoken, docile reinspirer of the Papacy; as Jeanne d’Arc, the maiden deliverer of a Nation; as St. Teresa, reformer of a great Order. All these, and countless others, would, quite evidently, have achieved less, not more, of interior light and of far-reaching helpfulness of a kind readily recognized by all specifically religious souls, had they been without the rest, the bracing, the experience furnished to them by their ecstasies and allied states and apprehensions.

TWO SPECIAL DIFFICULTIES. 1. _A false and a true test of mystical experience._
