Clement of Alexandria

For Paul too, in the Epistles, plainly does not disparage philosophy; but deems it unworthy of the man who has attained to the elevation of the Gnostic, any more to go back to the Hellenic "philosophy," figuratively calling it the rudiments of this world, as being most rudimentary, and a preparatory training for the truth. Wherefore also, writing to the Hebrews, who were declining again from faith to the law, he says, "Have ye not need again of one to teach you which are the first principles of the oracles of God, and are become such as have need of milk, and not of strong meat?" So also to the Colossians, who were Greek converts, "Beware lest any man spoil you by philosophy and vain deceit, after the tradition of men, after the rudiments of this world, and not after Christ," -enticing them again to return to philosophy, the elementary doctrine.

It is the prerogative of the Gnostic, then, to know how to make use of speech, and when, and how, and to whom. And already the apostle, by saying, "After the rudiments of the world, and not after Christ," makes the asseveration that the Hellenic teaching is elementary, and that of Christ perfect, as we have already intimated before.
