Divine Scripture is to be interpreted spiritually and the treasures it contains are revealed only through the Holy Spirit to the spiritual. Hence the unspiritual man cannot receive the revelation of these treasures (cf. 1 Corinthians 2:14). The ceaseless flow of his own thoughts makes it impossible for him to understand or listen to anything said by someone else. For he lacks the Spirit of God, that searches the depths of God (cf. 1 Corinthians 2:10) and knows the things of God. He possesses only the material spirit of the world, full of jealousy and envy, of strife and discord; and for this reason he thinks it foolish to inquire into the sense and meaning of the written word. Unable to understand that everything in divine Scripture concerning things divine and human is to be interpreted spiritually, he mocks those who do interpret it in this way. Calling such people not ‘spiritual’, or ‘guided by the Spirit’, but ‘anagogical’, he twists and distorts their words and their divine intellections as much as he can, like the notorious Demas (cf. 2 Timothy 4:10).
The spiritual man does not behave in this manner; on the contrary, inspired by the Holy Spirit, he discerns all things, but he himself cannot be called to account by anyone. For he has the intellect of Christ, and that no one can teach (cf. 1 Corinthians 2:15-16).
