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
Jerome
AD 420
This oration is directed against all who act with iniquity. It is summarized neatly in one sentence by the seventy-second Psalm, wherein the prophet says, “How good is the God of Israel to those who are upright in heart! But my feet had almost been moved and my step had nearly slipped, for I was jealous of sinners when I saw the ease of their lives.” This is said particularly against heretics, who, because they are impious, prosper in their ways and generate children of their own, whom they deceive with heresy. They conspire and act with iniquity, all of this for the purpose of plundering the church and of portraying themselves as having been planted by God and having sunk roots and produced children and bore fruit, even while continuing in the wickedness of their intentions. Although they frequently repeat the name of Christ, God does not inhabit them, as Isaiah said: “This people honors me with their lips, but their heart is far from me.”
“And you know me, Lord, you see me and you prove my heart to be with you. Gather them as sheep for the slaughter and sanctify them on the killing day.” There is no scandal, he says, because all the impious or heretics flourish only for a while, but “you know me, Lord, and you prove my heart to be with you.”
