No, that could not be! “Let us therefore remember, that things which are really bound together” in the language-speaker –namely ‘speaking’ and ‘understanding’ — “are kept separate here, for the sake of teaching — and not because it can…fall out that way!”
Calvin on the word ‘understanding’ in I Cor. 14:14
Comments Calvin: “Paul thinks it a great fault if the understanding takes no part in prayer. No wonder! For what else do we do in praying, but pour out our thoughts and desires before God?”
“Spiritual prayer is a means of worshipping God. What is more out of keeping with its very nature — than its coming only from the lips, and not from the innermost recesses of the soul?” For then, it is “the devil” who has “deprived the world of its senses” — if “men believe that they are praying properly, when they [only] make their lips move!”
