1 Corinthians 14:37

If any man think himself to be a prophet
Or "seems to be a prophet", and is really one; for the apostle does not so much design to strike at the pride, vanity, and appearances of false prophets, as to observe, that those that are really prophets, have the gift of prophesy, either of foretelling future events, or a peculiar gift of preaching the Gospel, and explaining the Scriptures, will allow what he had said to be right:

or spiritual;
not merely one that has the Spirit of God, is regenerated and sanctified by him, in opposition to a natural and carnal man; or one that has a larger knowledge of spiritual things, in distinction from a babe in Christ; but one that is endued with spiritual gifts, with the extraordinary gifts of the Spirit, with a discerning of spirits; as there were such among them no doubt, as well as prophets, and who were distinct from them, having the word of wisdom and knowledge:

let him acknowledge that the things that I write unto you are the
commandments of the Lord;
if he is a true prophet, and really a spiritual man, he will clearly see, and therefore ought to own, that the rules here prescribed concerning speaking with tongues and prophesying, and concerning the intolerableness, unlawfulness, and indecency of women's speaking in public assemblies, are perfectly agreeable to the commands of Christ, and are to be esteemed as such, being delivered under the influence and direction of his Spirit; and which the prophet and spiritual man must discern and allow, if they have the Spirit of God; for whatever was commanded by the apostles under divine inspiration, was all one as if immediately commanded by Christ himself.
