When he was speaking concerning those Jews, he said, "When, meanwhile, the customs of that most accursed nation have gained such strength that they have been now received in all lands, the conquered have given laws to the conquerors." By these words he expresses his astonishment; and, not knowing what the providence of God was leading him to say, subjoins in plain words an opinion by which he showed what he thought about the meaning of those sacred institutions: "For," he says, "those, however, know the cause of their rites, whilst the greater part of the people know not why they perform theirs." But concerning the solemnities of the Jews, either why or how far they were instituted by divine authority, and afterwards, in due time, by the same authority taken away from the people of God, to whom the mystery of eternal life was revealed, we have both spoken elsewhere, especially when we were treating against the Manichæans, and also intend to speak in this work in a more suitable place. 12. _That when once the vanity of the gods of the nations has been exposed, it cannot be doubted that they are unable to bestow eternal life on any one, when they cannot afford help even with respect to the things of this temporal life._ Now, since there are three theologies, which the Greeks call respectively mythical, physical, and political, and which may be called in Latin fabulous, natural, and civil; and since neither from the fabulous, which even the worshippers of many and false gods have themselves most freely censured, nor from the civil, of which that is convicted of being a part, or even worse than it, can eternal life be hoped for from any of these theologies,--if any one thinks that what has been said in this book is not enough for him, let him also add to it the many and various dissertations concerning God as the giver of felicity, contained in the former books, especially the fourth one.
