Confessions

^8. But yet who was it that ordered Manichæus to write on these things likewise, skill in which was not necessary to piety? For You have told man to behold piety and wisdom, of which he might be in ignorance although having a complete knowledge of these other things; but since, knowing not these things, he yet most impudently dared to teach them, it is clear that he had no acquaintance with piety. For even when we have a knowledge of these worldly matters, it is folly to make a profession of them; but confession to You is piety. It was therefore with this view that this straying one spoke much of these matters, that, standing convicted by those who had in truth learned them, the understanding that he really had in those more difficult things might be made plain. For he wished not to be lightly esteemed, but went about trying to persuade men “that the Holy Ghost, the Comforter and Enricher of Your faithful ones, was with full authority personally resident in him.” When, therefore, it was discovered that his teaching concerning the heavens and stars, and the motions of sun and moon, was false, though these things do not relate to the doctrine of religion, yet his sacrilegious arrogance would become sufficiently evident, seeing that not only did he affirm things of which he knew nothing, but also perverted them, and with such egregious vanity of pride as to seek to attribute them to himself as to a divine being.

9. For when I hear a Christian brother ignorant of these things, or in error concerning them, I can bear with patience to see that man hold to his opinions; nor can I apprehend that any want of knowledge as to the situation or nature of this material creation can be injurious to him, so long as he does not entertain belief in anything unworthy of You, O Lord, the Creator of all. But if he conceives it to pertain to the form of the doctrine of piety, and presumes to affirm with great obstinacy that whereof he is ignorant, therein lies the injury. And yet even a weakness such as this in the dawn of faith is borne by our Mother Charity, till the new man may grow up “unto a perfect man,” and not be “carried about with every wind of doctrine.” But in him who thus presumed to be at once the teacher, author, head, and leader of all whom he could induce to believe this, so that all who followed him believed that they were following not a simple man only, but Your Holy Spirit, who would not judge that such great insanity, when once it stood convicted of false teaching, should be abhorred and utterly cast off? But I had not yet clearly ascertained whether the changes of longer and shorter days and nights, and day and night itself, with the eclipses of the greater lights, and whatever of the like kind I had read in other books, could be expounded consistently with his words. Should I have found myself able to do so, there would still have remained a doubt in my mind whether it were so or no, although I might, on the strength of his reputed godliness, rest my faith on his authority.
