A Plea for the Christians by Athenagoras
Three things are alleged against us: atheism, Thyestean feasts, OEdipodean intercourse. But if these charges are true, spare no class: proceed at once against our crimes; destroy us root and branch, with our wives and children, if any Christian is found to live like the brutes. And yet even the brutes do not touch the flesh of their own kind; and they pair by a law of nature, and only at the regular season, not from simple wantonness; they also recognise those from whom they receive benefits.
