Oecumenius : "confessing and proclaiming their deeds." It is necessary for every faithful person to confess his own sins, and to turn away by reproving himself, so as no longer to do the same things, in order that he may be justified according to the saying: "You first confess your sins, so that you may be justified." (James 5:16) It should also be noted in what follows that although their magical books were valuable, like the finest possessions of those who live in the world, those who believed in Christ did not sell them but burned them; for, although there were others there who wished to acquire such books, first so that no one might share in the soul-destroying influence that comes from them, and secondly so that no one might obtain anything on account of such a cause. For just as gain from fornication was forbidden to be offered to God, so neither did the apostles judge it right or acceptable that the money from this source should be placed at their feet.
