Against Celsus: Book III 72Chapter LXXII

In the next place, speaking as in the person of a teacher of our doctrine, he expresses himself as follows: "Wise men reject what we say, being led into error, and ensnared by their wisdom." In reply to which we say that, since wisdom is the knowledge of divine and human things and of their causes, or, as it is defined by the word of God, "the breath of the power of God, and a pure influence flowing from the glory of the Almighty; and the brightness of the everlasting light, and the unspotted mirror of the power of God, and the image of His goodness," no one who was really wise would reject what is said by a Christian acquainted with the principles of Christianity, or would be led into error, or ensnared by it. For true wisdom does not mislead, but ignorance does, while of existing things knowledge alone is permanent, and the truth which is derived from wisdom. But if, contrary to the definition of wisdom, you call any one whatever who dogmatizes with sophistical opinions wise, we answer that in conformity with what you call wisdom, such an one rejects the words of God, being misled and ensnared by plausible sophisms. And since, according to our doctrine, wisdom is not the knowledge of evil, but the knowledge of evil, so to speak, is in those who hold false opinions and who are deceived by them, I would therefore in such persons term it ignorance rather than wisdom.
