John Chrysostom, on Jer 3:1

“It is commonly said: If a man put away his wife, and she go from him, and marry another man, shall he return to her any more? shall not that woman be polluted, and defiled? but thou hast prostituted thyself to many lovers: nevertheless return to me, saith the Lord, and I will receive thee.”

“He has come as a physician, not as a judge. Therefore, in like manner, as those of old took harlots for wives, even so God too married to himself the nature that had played the harlot. This also prophets from the beginning declare to have taken place with respect to the synagogue. But that spouse was ungrateful toward him who had been a husband to her, while on the contrary, the church, when once delivered from the evils received from our ancestors, continued to embrace the Bridegroom.”
