The Egyptians, then, having been taught to worship Antinous, will, if you compare him with Apollo or Zeus, endure such a comparison, Antinous being magnified in their estimation through being classed with these deities; for Celsus is clearly convicted of falsehood when he says, “that they will not endure his being compared with Apollo or Zeus.” Whereas Christians (who have learned that their eternal life consists in knowing the only true God, who is over all, and Jesus Christ, whom He has sent; and who have learned also that all the gods of the heathen are greedy demons, which flit around sacrifices and blood, and other sacrificial accompaniments, in order to deceive those who have not taken refuge with the God who is over all, but that the divine and holy angels of God are of a different nature and will from all the demons on earth, and that they are known to those exceedingly few persons who have carefully and intelligently investigated these matters) will not endure a comparison to be made between them and Apollo or Zeus, or any being worshipped with odour and blood and sacrifices; some of them, so acting from their extreme simplicity, not being able to give a reason for their conduct, but sincerely observing the precepts which they have received; others, again, for reasons not to be lightly regarded, nay, even of a profound description, and (as a Greek would say) drawn from the inner nature of things; and among the latter of these God is a frequent subject of conversation, and those who are honoured by God, through His only-begotten Word, with participation in His divinity, and therefore also in His name. They speak much, too, both regarding the angels of God and those who are opposed to the truth, but have been deceived; and who, in consequence of being deceived, call them gods or angels of God, or good demons, or heroes who have become such by the transference into them of a good human soul. And such Christians will also show, that as in philosophy there are many who appear to be in possession of the truth, who have yet either deceived themselves by plausible arguments, or by rashly assenting to what was brought forward and discovered by others; so also, among those souls which exist apart from bodies, both angels and demons, there are some which have been induced by plausible reasons to declare themselves gods. And because it was impossible that the reasons of such things could be discovered by men with perfect exactness, it was deemed safe that no mortal should entrust himself to any being as to God, with the exception of Jesus Christ, who is, as it were, the Ruler over all things, and who both beheld these weighty secrets, and made them known to a few.
