was the contradiction which it contains not felt? The content of revelation is to be rational; but does that which is rational require a revelation? How the proposition was understood by the different Apologists requires examination. _Aristides._ He first gives an exposition of monotheism and the monotheistic cosmology (God as creator and mover of the universe, as the spiritual, perfect, almighty Being, whom all things need, and who requires nothing). In the second chapter he distinguishes, according to the Greek text, three, and, according to the Syriac, four classes of men (in the Greek text polytheists, Jews, Christians, the polytheists being divided into Chaldeans, Greeks, and Egyptians; in the Syriac barbarians, Greeks, Jews, Christians), and gives their origin. He derives the Christians from Jesus Christ and reproduces the Christian _kerygma_ (Son of the Most High God, birth from the Virgin, 12 disciples, death on the cross, burial, resurrection, ascension, missionary labours of the 12 disciples). After this, beginning with the third chapter, follows a criticism of polytheism, that is, the false theology of the barbarians, Greeks, and Egyptians (down to chapter 12). In the 13th chapter the Greek authors and philosophers are criticised, and the Greek myths, as such, are shown to be false. In the 14th chapter the Jews are introduced (they are monotheists and their ethical system is praised; but they are then reproached with worshipping of angels and a false ceremonial). In the 15th chapter follows a description of the Christians, _i.e._, above all, of their pure, holy life. It is they who have found the truth, because they know the creator of heaven and earth. This description is continued in chapters 16 and 17: "This people is new and there is a divine admixture in it." The Christian writings are recommended to the emperor.
