But not only from these considerations may one appreciate their godlessness, but also from their discordant opinions about the idols themselves. For if they be gods according to their assertion and their speculations, to which of them is one to give allegiance, and which of them is one to judge to be the higher, so as either to worship God with confidence, or as they say to recognise the Deity by them without ambiguity? For not the same beings are called gods among all; on the contrary, for every nation almost there is a separate god imagined. And there are cases of a single district and a single town being at internal discord about the superstition of their idols. 2. The Phœnicians, for example, do not know those who are called gods among the Egyptians, nor do the Egyptians worship the same idols as the Phœnicians have. And while the Scythians reject the gods of the Persians, the Persians reject those of the Syrians. But the Pelasgians also repudiate the gods in Thrace, while the Thracians know not those of Thebes. The Indians moreover differ from the Arabs, the Arabs from the Ethiopians, and the Ethiopians from the Arabs in their idols. And the Syrians worship not the idols of the Cilicians, while the Cappadocian nation call gods beings different from these. And while the Bithynians have adopted others, the Armenians have imagined others again. And what need is there for me to multiply examples? The men on the continent worship other gods than the islanders, while these latter serve other gods than those of the main lands. 3. And, in general, every city and village, not knowing the gods of its neighbours, prefers its own, and deems that these alone are gods. For concerning the abominations in Egypt there is no need even to speak, as they are before the eyes of all: how the cities have religions which are opposite and incompatible, and neighbours always make a point of worshipping the opposite of those next to them: so much so that the crocodile, prayed to by some, is held in abomination by their neighbours, while the lion, worshipped as a god by others, their neighbours, so far from worshipping, slay, if they find it, as a wild beast; and the fish, consecrated by some people, is used as food in another place. And thus arise fights and riots and frequent occasions of bloodshed, and every indulgence of the passions among them. 4. And strange to say, according to the statement of historians, the very Pelasgians, who learned from the Egyptians the names of the gods, do not know the gods of Egypt, but worship others instead. And, speaking generally, all the nations that are infatuated with idols have different opinions and religions, and consistency is not to be met with in any one case. Nor is this surprising. 5. For having fallen from the contemplation of the one God, they have come down to many and diverse objects; and having turned from the Word of the Father, Christ the Saviour of all, they naturally have their understanding wandering in many directions. And just as men who have turned from the sun and have come into dark places go round by many pathless ways, and see not those who are present, while they imagine those to be there who are not, and seeing see not; so they that have turned from God and whose soul is darkened, have their mind in a roving state, and like men who are drunk and cannot see, imagine what is not true.
24. The so-called gods of one place are used as victims in another.
This, then, is no slight proof of their real godlessness. For, the gods for every city and country being many and various, and the one destroying the god of the other, the whole of them are destroyed by all. For those who are considered gods by some are offered as sacrifices and drink-offerings to the so-called gods of others, and the victims of some are conversely the gods of others. So the Egyptians serve the ox, and Apis, a calf, and others sacrifice these animals to Zeus. For even if they do not sacrifice the very animals the others have consecrated, yet by sacrificing their fellows they seem to offer the same. The Libyans have for god a sheep which they call Ammon, and in other nations this animal is slain as a victim to many gods. 2. The Indians worship Dionysus, using the name as a symbol for wine, and others pour out wine as an offering to the other gods. Others honour rivers and springs, and above all the Egyptians pay special honour to water, calling them gods. And yet others, and even the Egyptians who worship the waters, use them to wash off the dirt from others and from themselves, and ignominiously throw away what is used. While nearly the whole of the Egyptian system of idols consists of what are victims to the gods of other nations, so that they are scorned even by those others for deifying what are not gods, but, both with others and even among themselves, propitiatory offerings and victims.
25. Human sacrifice. Its absurdity. Its prevalence. Its calamitous results.
But some have been led by this time to such a pitch of irreligion and folly as to slay and to offer in sacrifice to their false gods even actual men, whose figures and forms the gods are. Nor do they see, wretched men, that the victims they are slaying are the patterns of the gods they make and worship, and to whom they are offering the men. For they are offering, one may say, equals to equals, or rather, the higher to the lower; for they are offering living creatures to dead, and rational beings to things without motion. 2. For the Scythians who are called Taurians offer in sacrifice to their Virgin, as they call her, survivors from wrecks, and such Greeks as they catch, going thus far in impiety against men of their own race, and thus exposing the savagery of their gods, in that those whom Providence has rescued from danger and from the sea, they slay, almost fighting against Providence; because they frustrate the kindness of Providence by their own brutal character. But others, when they are returned victorious from war, thereupon dividing their prisoners into hundreds, and taking a man from each, sacrifice to Ares the man they have picked out from each hundred. 3. Nor is it only Scythians who commit these abominations on account of the ferocity natural to them as barbarians: on the contrary, this deed is a special result of the wickedness connected with idols and false gods. For the Egyptians used formerly to offer victims of this kind to Hera, and the Phœnicians and Cretans used to propitiate Cronos in their sacrifices of children. And even the ancient Romans used to worship Jupiter Latiarius, as he was called, with human sacrifices, and some in one way, some in another, but all without exception committed and incurred the pollution: they incurred it by the mere perpetration of the murderous deeds, while they polluted their own temples by filling them with the smoke of such sacrifices. 4. This then was the ready source of numerous evils to mankind. For seeing that their false gods were pleased with these things, they immediately imitated their gods with like misdoings, thinking that the imitation of superior beings, as they considered them, was a credit to themselves. Hence mankind was thinned by murders of grown men and children, and by licence of all kinds. For nearly every city is full of licentiousness of all kinds, the result of the savage character of its gods; nor is there one of sober life in the idols' temples save only he whose licentiousness is witnessed to by them all.
26. The moral corruptions of Paganism all admittedly originated with the gods.
