Origen

“ Now, if one were to lay it down that works are wrought by means of sorcery, but would not grant that there are also works which are the product of divine power, he would seem to me to resemble him who should admit the existence of sophisms and plausible arguments, which have the appearance of establishing the truth, although really undermining it, while denying that truth had anywhere a home among men, or a dialectic which differed from sophistry. ”

“ And we might further say, in answer to the calumnies of Celsus, Are those to be regarded as miracles which are wrought through sorcery by wicked demons, but those not which are performed by a nature that is holy and divine? and does human life endure the worse, but never receive the better? Now it appears to me that we must lay it down as a general principle, that as, wherever anything that is evil would make itself to be of the same nature with the good, there must by all means be something that is good opposed to the evil ”

“ For wickedness and sorcery would not have led a whole nation to rise not only above idols and images erected by men, but also above all created things, and to ascend to the uncreated origin of the God of the universe. ”
