George Leo Haydock, on 1Cor 14:2

“For he that speaketh in a tongue, speaketh not unto men, but unto God: for no man heareth. Yet by the Spirit he speaketh mysteries.”

“He that speaketh in a tongue, which others at least understand not: nay, which sometimes, perhaps, by the 14th and 15th verse, he himself that spoke tongues, did not understand, can only be said to speak to God. In spirit he speaketh mysteries, edifies himself, because in his spirit he is piously and devoutly affected; but he must endeavour that the Church, or people present, may be also edified. Let him then pray for the other gift of interpreting, what he speaks, or let another interpret. (Witham) — Not to men. Viz., so as to be heard, that is, so as to be understood by them. (Witham)”
