For he that speaks in an unknown tongue speaks not unto men, but unto God: for no man understands him; but in the spirit he speaks mysteries.
All Commentaries on 1 Corinthians 14:2 Go To 1 Corinthians 14
Cornelius a Lapide
AD 1637
He that speaketh in a tongue, &c. S. Augustine (de Gen. ad Litt. lib. xii.), Primasius, and Cajetan read the nominative in the last clause of this verse, "Howbeit the Spirit speaketh mysteries," The meaning then would be: The Holy Spirit speaks of hidden mysteries in the Holy Scriptures, which cannot be understood, except some prophet or doctor interpret them. But this meaning is foreign to the context, and this reading is not supported by the Greek or Latin copies.
