35 In regard to the distribution of the word, to mention last the first of our duties, of that divine and exalted word, which everyone now is ready to discourse upon; if anyone else boldly undertakes it and supposes it within the power of every man's intellect, I am amazed at his intelligence, not to say his folly. To me indeed it seems no slight task, and one requiring no little spiritual power, to give in due season to each his portion of the word, and to regulate with judgment the truth of our opinions, which are concerned with such subjects as the world or worlds, matter, soul, mind, intelligent natures, better or worse, providence which holds together and guides the universe, and seems in our experience of it to be governed according to some principle, but one which is at variance with those of earth and of men.
