Before the advent of the Lord philosophy was necessary to the Greeks for righteousness. And now it becomes useful to piety, being a kind of preparatory training to those who attain to faith through demonstration. “For thy foot,” it is said, “will not stumble” if thou refer what is good, whether belonging to the Greeks or to us, to Providence. For God is the cause of all good things; but of some primarily, as of the Old and the New Testament, and of others by consequence, as philosophy. Perchance, too, philosophy was given to the Greeks directly till the Lord should call the Greeks also. For this was a schoolmaster to bring the Hellenic mind to Christ, as was the law to bring the Hebrews. Philosophy, therefore, was a preparation, paving the way for him who is perfected in Christ. “Now,” says Solomon, “defend wisdom, and it will exalt thee, and it will shield thee with a crown of pleasure.”(66) For when thou hast strengthened wisdom with a breastwork by philosophy, and with expenditure, thou wilt preserve her unassailable by sophists. The way of truth is therefore one. But into it, as into a perennial river, streams flow from every side. (_b_) Clement of Alexandria, _Stromata_, VII, 10. (MSG, 9:47.) See Clement of Alexandria, _VIIth Book of the Stromateis_, ed. by Hort and Mayor, London, 1902. In making faith suffice for salvation, Clement clearly distinguishes his position from that of the Gnostics, though he uses the term “gnostic” as applicable to Christians. See next passage. Knowledge [gnosis], so to speak, is a perfecting of man as man, which is brought about by acquaintance with divine things; in character, life, and word harmonious and consistent with itself and the divine Word. For by it faith is made perfect, inasmuch as it is solely by it that the man of faith becomes perfect. Faith is an internal good, and without searching for God confesses His existence and glorifies Him as existent. Hence by starting with this faith, and being developed by it, through the grace of God, the knowledge respecting Him is to be acquired as far as possible.… But it is not doubting, in reference to God, but believing, that is the foundation of knowledge. But Christ is both the foundation and the superstructure, by whom are both the beginning and the end. And the extreme points, the beginning and the end, I mean faith and love, are not taught. But knowledge, which is conveyed from communication through the grace of God as a deposit, is intrusted to those who show themselves worthy of it; and from it the worth of love beams forth from light to light. For it is said, “To him that hath shall be given” [_cf._ Matt. 13:12]—to faith, knowledge; and to knowledge, love; and to love, the inheritance.…
