_Theophilus_ agrees with Tatian, in so far as he everywhere appears to contrast Christianity with philosophy. The religious and moral culture of the Greeks is derived from their poets (historians) and philosophers (ad Autol. II. 3 fin. and elsewhere). However, not only do poets and philosophers contradict each other (II. 5); but the latter also do not agree (II. 4. 8: III. 7), nay, many contradict themselves (III. 3). Not a single one of the so-called philosophers, however, is to be taken seriously;[401] they have devised myths and follies (II. 8); everything they have set forth is useless and godless (III. 2); vain and worthless fame was their aim (III. 3). But God knew beforehand the "drivellings of these hollow philosophers" and made his preparations (II. 15). He of old proclaimed the truth by the mouth of prophets, and these deposited it in holy writings. This truth refers to the knowledge of God, the origin and history of the world, as well as to a virtuous life. The prophetic testimony in regard to it was continued in the Gospel.[402] Revelation, however, is necessary because this wisdom of the philosophers and poets is really demon wisdom, for they were inspired by devils.[403] Thus the most extreme contrasts appear to exist here. Still, Theophilus is constrained to confess that truth was not only announced by the Sibyl, to whom his remarks do not apply, for she is (II. 36): [Greek: en Ellesin kai en tois loipois ethnetin genomene prophetis], but that poets and philosophers, "though against their will," also gave clear utterances regarding the justice, the judgment, and the punishments of God, as well as regarding his providence in respect to the living and the dead, or, in other words, about the most important points (II. 37, 38, 8 fin.). Theophilus gives a double explanation of this fact. On the one hand he ascribes it to the imitation of holy writings (II. 12, 37: I. 14), and on the other he admits that those writers, when the demons abandoned them ([Greek: te psyche eknepsantes ex auton]), of themselves displayed a knowledge of the divine sovereignty, the judgment etc., which agrees with the teachings of the prophets (II. 8). This admission need not cause astonishment; for the freedom and control of his own destiny with which man is endowed (II. 27) must infallibly lead him to correct knowledge and obedience to God, as soon as he is no longer under the sway of the demons. Theophilus did not apply the title of philosophy to Christian truth, this title being in his view discredited; but Christianity is to him the "wisdom of God," which by luminous proofs convinces the men who reflect on their own nature.[404]
