4 But we receive those things which you have written as if they were our own; nor do we read them cursorily, but by frequent repetition have committed them to memory. Nor does it hinder saving usefulness, either to repeat the same things for the confirmation of the truth, or, moreover, to add some things for the sake of accumulating proof. But if anything has been added by us, it is not added as if there had been too little said by you; but since the divine discourse surpasses human nature, and the soul cannot conceive or grasp the whole and perfect word, therefore also the number of prophets is so great, that the divine wisdom in its multiplicity may be distributed through many.
Whence also he who first speaks in prophecy is bidden to be silent if a revelation be made to a second. For which reason it happens of necessity among us, that year by year we, the elders and prelates, assemble together to arrange those matters which are committed to our care, so that if any things are more serious they may be directed by the common counsel. Moreover, we do this that some remedy may be sought for by repentance for lapsed brethren, and for those wounded by the devil after the saving layer, not as though they obtained remission of sins from us, but that by our means they may be converted to the understanding of their sins, and may be compelled to give fuller satisfaction to the Lord.
