Therefore the Lord said,
Since this people draw near me with their mouth, and with their lips do honor me, but have removed their heart far from me, and their fear toward me is taught by the precept of men:
All Commentaries on Isaiah 29:13 Go To Isaiah 29
Gregory of Nyssa
AD 394
For speaking in this way or in that is not the cause of the thought within us, but the hidden conception of the heart supplies the motive for such and such words, “for from the abundance of the heart the mouth speaks.” We make the words interpret the thought; we do not by a reverse process gather the thought from the words. Should both be at hand, a person may certainly be ready in both, in clever thinking and clever expression; but if the one should be wanting, the loss to the illiterate is slight, if the knowledge in his soul is perfect in the direction of moral goodness. “This people honors me with their lips, but their heart is far from me.” What is the meaning of that? That the right attitude of the soul toward the truth is more precious than the propriety of phrases in the sight of God, who hears the “groanings that cannot be uttered.” Phrases can be used in opposite senses; the tongue readily serving, at his will, the intention of the speaker; but the disposition of the soul, as it is, so is it seen by him who sees all secrets.
