Jer 3:9

“Let us now proceed to consider the mode of his loving discipline, with the aid of the prophetic testimony. Admonition, then, is loving care's censure and produces understanding. Such is Christ the Educator in his admonitions, as when he says in the Gospel, "How often would I have gathered your children, as a bird gathers her young ones under her wings, and you did not allow it!" And again, the Scripture admonishes, saying, "And they committed adultery with wood and stone and burned incense to Baal." For it is a very great proof of his love, that, though knowing well the shamelessness of the people who had kicked and bounded away, he notwithstanding exhorts them to repentance and says by Ezekiel, "Son of man, you live in the midst of scorpions; nevertheless, speak to them, if perhaps they will hear."”

“Admonition, then, is loving care's censure and produces understanding. Such is Christ the Educator in his admonitions, as when he says in the Gospel, "How often would I have gathered your children, as a bird gathers her young ones under her wings, and you would not!" And again, the Scripture admonishes, saying, "And they committed adultery with stock and stone and burned incense to Baal." For it is a very great proof of God's love that, though knowing well the shamelessness of the people who had kicked and bounded away, he nevertheless exhorts them to repentance. He says by Ezekiel, "Son of man, you dwell in the midst of scorpions. Nevertheless, speak to them, if by chance they will hear." Further, to Moses he says, "Go and tell Pharaoh to send my people forth, but I know that he will not send them forth."”

“It is not only bodily sin that is called fornication and adultery, but any sin you have committed, and especially transgression against that which is divine. Perhaps you ask how we can prove this. "They prostituted themselves," it says "with things they made." Don't you see an impudent act of fornication? And again, "They committed adultery with pieces of wood." Don't you see a kind of adulterous religion? Do not then commit spiritual adultery, while keeping your bodies chaste.”

“Those who place themselves far from your care and choose to serve idols will reap the destructive fruit of defection. He calls idolatry infidelity here. God likewise says also through Jeremiah, "She went up every high hill and under every green tree and was unfaithful there. I said, after all this infidelity of hers, 'Return unto me,' and she did not return." Again, "She committed adultery with tree and stone," meaning, "Leaving me, her spouse, she served false gods." Accordingly, here too he called the worship of idols infidelity.”
