1 Corinthians 2:13

Clement of Alexandria Stromata Book I

And the apostle says, "Which things we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth."[196]

Clement of Alexandria Stromata Book V

For he who is still blind and dumb, not having understanding, or the undazzled and keen vision of the contemplative soul, which the Saviour confers, like the uninitiated at the mysteries, or the unmusical at dances, not being yet pure and worthy of the pure truth, but still discordant and disordered and material, must stand outside of the divine choir. "For we compare spiritual things with spiritual."[53]

Hippolytus Refutation of All Heresies Book V

But the natural man receiveth not the things of the Spirit of God, for they are foolishness unto him."[94]

Hippolytus Refutation of All Heresies Book VII

This is the wisdom spoken in a mystery, concerning which, says (Basilides), Scripture uses the following expressions: "Not in words taught of human wisdom, but in (those) taught of the Spirit."[46]
