Albert Barnes Commentary 1 Corinthians 2:15

"But he that is spiritual judgeth all things, and he himself is judged of no man." — 1 Corinthians 2:15 (ASV)

But he that is spiritual. This refers to the person who is enlightened by the Holy Spirit, in contrast to the one who is under the influence of the senses only.

Judge. The Greek word is discerns (margin); it is the same word as in the previous verse. This means that the spiritual person has a discernment of those truths about which the sensual person was blind and ignorant.

All things. This does not mean absolutely all things, nor that the spiritual person is omniscient. Instead, it means that this person has a view of those things to which the apostle was referring—that is, the things which are revealed to people by the Holy Spirit.

Yet he himself is judged. The Greek, as noted in the margin, is "is discerned;" that is, his feelings, principles, views, hopes, fears, and joys cannot be fully understood and appreciated by any natural or sensual person.

The natural person does not comprehend the principles that motivate the spiritual person; he does not enter into his joys; he does not sympathize with him in his feelings. This is a matter of simple truth and universal observation.

The reason for this is added in the following verse: because the Christian is influenced by the Lord, and the natural person does not know the Lord, so the natural person cannot know the one who is influenced by Him—that is, the Christian.
