“For if thou call on wisdom and knowledge with a loud voice, and seek it as treasures of silver, and eagerly track it out, thou shalt understand godliness and find divine knowledge.”[846] The prophet says this in contradiction to the knowledge according to philosophy, which teaches us to investigate in a magnanimous and noble manner, for our progress in piety. He opposes, therefore, to it the knowledge which is occupied with piety, when referring to knowledge, when he speaks as follows: “For God gives wisdom out of His own mouth, and knowledge along with understanding, and treasures up help for the righteous.” For to those who have been justified by philosophy, the knowledge which leads to piety is laid up as a help. CHAPTER V. PHILOSOPHY THE HANDMAID OF THEOLOGY Accordingly, before the advent of the Lord, philosophy was necessary to the Greeks for righteousness. And now it becomes conducive 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.”[847] 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 and primarily, till the Lord should call the Greeks. For this was a schoolmaster to bring “the Hellenic mind,” as the law, the Hebrews, “to Christ.”[848] 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.”[849] For when thou hast strengthened wisdom with a cope by philosophy, and with right expenditure, thou wilt preserve it unassailable by sophists. The way of truth is therefore one. But into it, as into a perennial river, streams flow from all sides. It has been therefore said by inspiration: “Hear, my son, and receive my words; that thine may be the many ways of life. For I teach thee the ways of wisdom; that the fountains fail thee not,”[850] which gush forth from the earth itself. Not only did He enumerate several ways of salvation for any one righteous man, but He added many other ways of many righteous, speaking thus: “The paths of the righteous shine like the light.”[851] The commandments and the modes of preparatory training are to be regarded as the ways and appliances of life.
