Jer 5:21

“One who does not carefully weigh every word of the opinions uttered cannot rightly discover the value of the assertion. For someone like this, who only possesses skill in disputation and ornaments of speech, cannot penetrate to the very heart of Scripture and the mysteries of its spiritual meanings. True knowledge is acquired only by true worshipers of God. And certainly this people does not possess it to whom it is said, "Hear, O foolish people, you who have no heart, you who have eyes but do not see and who have ears but do not hear." And again, "Because you have rejected knowledge, I also will reject you from acting as my priest." It is said that in Christ "all the treasures of wisdom and knowledge are hidden." So how can we hold the opinion that someone has acquired spiritual knowledge when that person has not even wanted to find Christ, or, when he does find him, blasphemes him with impious lips or at least defiles the catholic faith by his impure actions? "The Spirit of God will avoid deception and does not live in a body that is subject to sin." There is then no way of arriving at spiritual knowledge but by this which one of the prophets has accurately described: "Sow to yourselves for righteousness. Reap the hope of life. Enlighten yourselves with the light of knowledge."”

“Not understanding him who had been anointed and sent and who was the author of such wonderful works, they returned to their usual ways and talked about him in a foolish and vain way. For although they wondered at the words of grace that proceeded out of his mouth, yet their wish was to treat them as valueless. They said, "Is not this the son of Joseph?" But what does this diminish from the glory of the worker of the miracles? What prevents him from being both venerated and admired, even had he been, as was supposed, the son of Joseph? Didn't you see the miracles? Satan fallen, the herds of devils vanquished, multitudes set free from various kinds of maladies? You praise the grace that was present in his teaching. Then do you, in Jewish fashion, think lightly of him because he considered Joseph for his father? How ignorant can you be! It is true what they say about them: "Lo! A people foolish and without understanding, they have eyes and see not, ears, and hear not."”

“That it is the height of folly not to fear, the Lord says in Jeremiah: "Hear, O foolish people, who have no heart: who having eyes, see not, and ears, and hear not. Will you then not fear me, and will you not be grieved at my presence? I who have set the sand as the boundary of the sea, an everlasting decree, which it shall not pass beyond." Do you not fear me?”
