1 Corinthians 14:5-7

Revised Standard Version Catholic Edition

⁵ Now I want you all to speak in tongues, but even more to prophesy. He who prophesies is greater than he who speaks in tongues, unless some one interprets, so that the church may be edified.

⁶ Now, brethren, if I come to you speaking in tongues, how shall I benefit you unless I bring you some revelation or knowledge or prophecy or teaching? ⁷ If even lifeless instruments, such as the flute or the harp, do not give distinct notes, how will any one know what is played?
