_Tertullian and Minucius Felix._[405] Whilst, in the case of the Greek Apologists, the acknowledgment of revelation appears conditioned by philosophical scepticism on the one hand, and by the strong impression of the dominion of the demons on the other, the sceptical element is not only wanting in the Latin Apologists, but the Christian truth is even placed in direct opposition to the sceptical philosophy and on the side of philosophical dogmatism, i.e., Stoicism.[406] Nevertheless the observations of Tertullian and Minucius Felix with regard to the essence of Christianity, viewed as philosophy and as revelation, are at bottom completely identical with the conception of the Greek Apologists, although it is undeniable that in the former case the revealed character of Christianity is placed in the background.[407] The recognition of this fact is exceedingly instructive, for it proves that the conception of Christianity set forth by the Apologists was not an individual one, but the necessary expression of the conviction that Christian truth contains the completion and guarantee of philosophical knowledge. To Minucius Felix (and Tertullian) Christian truth chiefly presents itself as the wisdom implanted by nature in every man (Oct. 16. 5). In so far as man possesses reason and speech and accomplishes the task of the "examination of the universe" ("inquisitio universitatis"), conditioned by this gift, he has the Christian truth, that is, he finds Christianity in his own constitution, and in the rational order of the world. Accordingly, Minucius is also able to demonstrate the Christian doctrines by means of the Stoic principle of knowledge, and arrives at the conclusion that Christianity is a philosophy, i.e., the true philosophy, and that philosophers are to be considered Christians in proportion as they have discovered the truth.[408] Moreover, as he represented Christian ethics to be the expression of the Stoic, and depicted the Christian bond of brotherhood as a cosmopolitan union of philosophers, who have become conscious of their natural similarity,[409] the revealed character of Christianity appears to be entirely given up. This religion is natural enlightenment, the revelation of a truth contained in the world and in man, the discovery of the one God from the open book of creation. The difference between him and an Apologist like Tatian seems here to be a radical one. But, if we look more closely, we find that Minucius--and not less Tertullian--has abandoned Stoic rationalism in vital points. We may regard his apologetic aim as his excuse for clearly drawing the logical conclusions from these inconsistencies himself. However, these deviations of his from the doctrines of the Stoa are not merely prompted by Christianity, but rather have already become an essential component of his philosophical theory of the world. In the first place, Minucius developed a detailed theory of the pernicious activity of the demons (cc. 26, 27).
