A man, then, can be "in this life" in two ways: he can be in it actually--that is, as actually using his bodily senses--and when he is thus "in the body" no contemplation such as belongs to this present life can attain to the vision of the Essence of God; or a man may be "in this life" potentially, and not actually; that is, his soul may be joined to his body as its informing principle, but in such fashion that it neither makes use of the bodily senses nor even of the imagination, and this is what takes place when a man is rapt in ecstasy: in this sense contemplation such as belongs to this life can attain to the vision of the Divine Essence. Consequently the highest degree of contemplation which is compatible with the present life is that which S. Paul had when he was rapt in ecstasy and stood midway between the state of this present life and the next. Some, however, say that the contemplative life can, even according to our present state of life, attain to the vision of the Divine Essence, thus: 1. Jacob said: _I have seen God face to face, and my soul hath been saved._[370] But the vision of the face of God is the vision of the Divine Essence. Whence it would seem that a man may by contemplation actually reach, even during this present life, to the vision of the Essence of God. But S. Denis says[371]: "If anyone saw God and understood what he saw, then it was not God he saw, but something belonging to Him." And similarly S. Gregory says[372]: "Almighty God is never seen in His Glory, but the soul gazes at something derived from It, and thus refreshed, makes advance, and so ultimately arrives at the glory of vision." Hence when Jacob said, _I saw God face to face_, we are not to understand that he saw the Essence of God, but that he saw some appearance--that is, some imaginary appearance--in which God spoke to him; or, as the Gloss of S. Gregory[373] has it, "Since we know people by the face, Jacob called knowledge of God His face." 2. Further, S. Gregory says[374]: "Contemplative men turn back within upon themselves in that they search into spiritual things, and do not carry with them the shadows of things corporeal; or if perchance they touch them, they drive them away with discreet hands. But when they would look upon the Infinite Light, they put aside all images which limit It, and in striving to arrive at a height superior to themselves, they become conquerors of their nature." But a man is only withheld from the vision of the Divine Essence, which is Infinite Light, by the necessity he is under of turning to corporeal images. From this it would seem that contemplation can, even in this present life, arrive at the sight of the Infinite Essential Light.
