521. As to the words "he was no more, for God took him" signifying the preservation of that doctrine for the use of posterity, the case with Enoch, as already said, is that he reduced to doctrine what in the Most Ancient Church had been a matter of perception, and which in the time of that church was not allowable; for to know by perception is a very different thing from learning by doctrine. They who are in perception have no need to learn by formulated doctrine that which they know already. For example: he who knows how to think well, has no occasion to be taught to think by any rules of art, for in this way his faculty of thinking well would be impaired, as is the case with those who stick fast in scholastic dust. To those who learn by perception, the Lord grants to know what is good and true by an inward way; but to those who learn from doctrine, knowledge is given by an external way, or that of the bodily senses; and the difference is like that between light and darkness. Consider also that the perceptions of the celestial man are such as to admit of no description, for they enter into the most minute and particular things, with all variety according to states and circumstances. But as it was foreseen that the perceptive faculty of the most Ancient Church would perish, and that afterwards mankind would learn by doctrines what is true and good, or by darkness would come to light, it is here said that "God took him" that is, preserved the doctrine for the use of posterity.
