Jer 3:19

“(Verse 19) But I said: How shall I put you among the children, and give you a desirable land, an excellent heritage of the armies of the nations? And I said, you shall call me father, and you shall not cease to follow me. For the excellent heritage of the armies of the nations, which the Seventy translated, Theodotion more significantly translated as the renowned heritage of the strongest nations, signifying Christ, who is the leader and Lord of all nations, to his name and the belief in his passion. He himself said to Israel: 'You shall call me Father.' And: 'Whoever believes in me, believes in the Father' (John II, 19). He himself promised: 'I will make you into sons: in the number, namely, of my sons, who have believed in me from the people of the nations; and to whom I have given the desirable land.' For as many as received him, he gave them the power to become sons of God (John I).”

“Our obstinacy and scorn, reflecting our spirit of rebellious disdain for him when he urges us to return and be saved, is described in the following comparison. He says, "And I said you shall call me Father and shall not cease to walk after me. But as a woman that despises her lover, so has the house of Israel despised me, says the Lord." It is only appropriate that as he has compared Jerusalem with an adulteress forsaking her husband, he compares his own love and persevering goodness with a man's undying love for a woman. For the goodness and love of God that he has always shown to the human race could not be more appropriately described by any comparison than the case of a man inflamed with most ardent love for a woman. God's love is overcome by no injuries that might make him stop caring for our salvation or that might drive him from his first intention as if he were defeated by our sins. Instead, he is consumed by a more burning passion for her, the more he sees that he is slighted and despised by her.”
