1 Corinthians 14:5-7

New Catholic Bible

⁵ I wish that all of you could speak in tongues, but I would much prefer that you could prophesy. For the one who prophesies is greater than the one who speaks in tongues, unless the latter can interpret what he is saying so that the Church may be built up.

⁶ Now suppose, brethren, that I should come to you and speak in tongues. Of what value would I be to you if you were unable to discern from my words any revelation or knowledge or prophecy or instruction? ⁷ Even inanimate things produce sound, such as a flute or a harp. If they do not produce distinct notes, how can anyone tell what tune is being played?
