1 Corinthians 14:5

I would that ye all spake with tongues. — To avoid danger of misunderstanding or misrepresentation the Apostle emphatically asserts here that the error which he is combating is the undue exaltation of the gift of tongues to the depreciation of other gifts. The teacher of religious truth to others, who thereby builds up the whole edifice of the body of Christ, is a greater one than he who is himself benefited by being possessed of profound but uncommunicable emotion.

Except he interpret. — The gift of interpreting might therefore belong to the same person who had the gift of tongues: and if he had this power of articulating for the benefit of others the emotion which he incoherently expresses in reverie, then the gift of tongues was useful to the Church at large, and so was as valuable as prophecy.
