1 Corinthians 2:15

But he that is spiritual judgeth all things, and he himself is judged of no man.

This applies to the company of inspired apostles and evangelists who delivered the great corpus of Christian doctrine. Such men, "endowed with the Holy Spirit could discern and discriminate what is of God, and teach all things God revealed."[38]

He that is spiritual judgeth ... himself is judged of no man ... In context, this applied to Paul himself, especially, as an affirmation of the authority he was about to exercise in correcting the disorders in Corinth. In the wider application, it means that only the inspired men of Paul's generation were to be credited with any capability whatever, as regards what is, or is not, the truth of God. The inspired company of apostles and evangelists were "judged of no man." As Lipscomb emphatically stated it, "This applies to the original revelations."[39] However, he went on to point out that Christians are instructed to "Believe not every spirit, but prove the spirits, whether they are of God; because many false prophets are gone out into the world" (1 John 4:1), adding that "Men now test all teaching by the truths delivered by the inspired men."[40] This, however, is a secondary application of Paul's affirmation in this verse. That secondary application, nevertheless, is valid, as outlined by Metz:

The Christian has a spiritual capacity to sift, to investigate, to examine, and to discern all things within the framework of the divine revelation of redemption. On the other hand, the natural man does not have the ability to subject the Christian way of life to examination and judgment, for he is completely unacquainted with the meaning of spiritual life.[41]
