1 Corinthians 14:18-20

Revised Standard Version Catholic Edition

¹⁸ I thank God that I speak in tongues more than you all; ¹⁹ nevertheless, in church I would rather speak five words with my mind, in order to instruct others, than ten thousand words in a tongue.

²⁰ Brethren, do not be children in your thinking; be babes in evil, but in thinking be mature.
