14:26-33 Religious exercises in public assemblies should have this view; Let all be done to edifying. As to the speaking in an unknown tongue, if another were present who could interpret, two miraculous gifts might be exercised at once, and thereby the church be edified, and the faith of the hearers confirmed at the same time. As to prophesying, two or three only should speak at one meeting, and this one after the other, not all at once. The man who is inspired by the Spirit of God will observe order and decency in delivering his revelations. God never teaches men to neglect their duties, or to act in any way unbecoming their age or station.

a doctrine—to impart and set forth to the congregation.
a tongue … a revelation—The oldest manuscripts transpose the order: "revelation … tongue"; "interpretation" properly following "tongue" (1Co 14:13).
Let all things be done unto edifying—The general rule under which this particular case fails; an answer to the question at the beginning of this verse. Each is bound to obey the ordinances of his church not adverse to Scripture. See Article XXXIV, Church of England Prayer Book.
