“But how, you will repeat, _can_ one have such certainty in respect to what one does not see? This question, I am powerless to answer. These are secrets of God’s omnipotence which it does not appertain to me to penetrate. All that I know is that I tell the truth; and I shall never believe that any soul who does not possess this certainty has ever been really united to God.”(252) The kinds of truth communicable in mystical ways, whether these be sensible or supersensible, are various. Some of them relate to this world,—visions of the future, the reading of hearts, the sudden understanding of texts, the knowledge of distant events, for example; but the most important revelations are theological or metaphysical. “Saint Ignatius confessed one day to Father Laynez that a single hour of meditation at Manresa had taught him more truths about heavenly things than all the teachings of all the doctors put together could have taught him.... One day in orison, on the steps of the choir of the Dominican church, he saw in a distinct manner the plan of divine wisdom in the creation of the world. On another occasion, during a procession, his spirit was ravished in God, and it was given him to contemplate, in a form and images fitted to the weak understanding of a dweller on the earth, the deep mystery of the holy Trinity. This last vision flooded his heart with such sweetness, that the mere memory of it in after times made him shed abundant tears.”(253) Similarly with Saint Teresa. “One day, being in orison,” she writes, “it was granted me to perceive in one instant how all things are seen and contained in God. I did not perceive them in their proper form, and nevertheless the view I had of them was of a sovereign clearness, and has remained vividly impressed upon my soul. It is one of the most signal of all the graces which the Lord has granted me.... The view was so subtile and delicate that the understanding cannot grasp it.”(254) She goes on to tell how it was as if the Deity were an enormous and sovereignly limpid diamond, in which all our actions were contained in such a way that their full sinfulness appeared evident as never before. On another day, she relates, while she was reciting the Athanasian Creed,— “Our Lord made me comprehend in what way it is that one God can be in three Persons. He made me see it so clearly that I remained as extremely surprised as I was comforted, ... and now, when I think of the holy Trinity, or hear It spoken of, I understand how the three adorable Persons form only one God and I experience an unspeakable happiness.” On still another occasion, it was given to Saint Teresa to see and understand in what wise the Mother of God had been assumed into her place in Heaven.(255)
