1 Corinthians 2:15

Next, pursuing his contrast, he states the cause of this, saying, "he knoweth not because they are spiritually discerned:" i.e. the things asserted require faith, and to apprehend them by reasonings is not possible, for their magnitude exceeds by a great deal the meanness of our understanding. Wherefore he saith, "but he that is spiritual judgeth all things, yet he himself is judged of no man." For he that has sight, beholds himself all things that appertain to the man that has no sight; but no sightless person discerns what the other is about. So also in the case before us, our own matters and those of unbelievers, all of them we for our part know; but ours, they know not henceforth any more. We know what is the nature of things present, what the dignity of things to come; and what some day shall become of the world when this state of things shall be no more, and what sinners shall suffer, and the righteous shall enjoy. And that things present are nothing worth, we both know, and their meanness we expose; (for to "discern" is also to expose;) and that the things to come are immortal and immoveable. All these things are known to the spiritual man; and what the natural man shall suffer when he is departed into that world; and what the faithful shall enjoy when he hath fulfilled his journey from this: none of which are known to the natural man. Wherefore also, subjoining a plain demonstration of what had been affirmed, he saith, "For who hath known the mind of the Lord, that he may instruct Him? But we have the mind of Christ." That is to say, the things which are in the mind of Christ, these we know, even the very things which He willeth and hath revealed. For since he had said, "the Spirit had revealed them;" lest any one should set aside the Son, he subjoins that Christ also shewed us these things. Not meaning this, that all the things which He knoweth, we know; but that all the things which we know are not human so as to be open to suspicion, but of His mind and spiritual. For the mind which we have about these things we have of Christ; that is, the knowledge which we have concerning the things of the faith is spiritual; so that with reason we are "judged of no man." For it is not possible that a natural man should know divine things. Wherefore also he said, "For who hath known the mind of the Lord?" implying that our own mind which we have about these things, is His mind. And this, "that he may instruct Him," he hath not added without reason, but with reference to what he had just now said, "the spiritual man no one discerneth." For if no man is able to know the mind of God, much less can he teach and correct it. For this is the meaning of, "that he may instruct Him." Seest thou how from every quarter he repels the wisdom which is without, and shews that the spiritual man knoweth more things and greater? For seeing that those reasons, "That no flesh should glory;" and, "For this cause hath He chosen the foolish things, that He might confound the wise men;" and, "Lest the Cross of Christ should be made void:" seemed not to the unbelievers greatly worthy of credit, nor yet attractive, or necessary, or useful, he finishes by laying down the principal reason; because in this way we most easily see from Whom we may have the means of learning even high things, and things secret, and things which are above us. For reason was absolutely made of none effect by our inability to apprehend through Gentile wisdom the things above us. You may observe, too, that it was more advantageous to learn in this way from the Spirit. For that is the easiest and clearest of all teaching. "But we have the mind of Christ." That is, spiritual, divine, that which hath nothing human. For it is not of Plato, nor of Pythagoras, but it is Christ Himself, putting His own things into our mind.
