From the early Church Fathers to now.
“Wherein shall I cleanse thy heart, saith the Lord God: seeing thou dost all these the works of a shameless prostitute?”
“As the law is not made for the just but for the lawless and those who are not subjected to God, so the teaching that warns us away from fornication does not become chaste but is for the lawless and the fornicators and the disobedient.”
“If you understand fornication of the flesh and the soul and the spirit, and if you see someone fornicating in them, you will also see Jerusalem fornicating herself three times.”
“There is no doubt that the word of the orator provokes the hero to worse things when a heretic builds up his hero in the perversions of heresy by what he says.”
“Those who have not completely gone away from religion but are conquered by sin and who want their sin to be hidden behave exactly like a prostitute who has been insulted.”
“(Verse 30, 31.) In what shall I cleanse your heart, says the Lord God, when you do all these works of a promiscuous and shameless woman? For you have made your brothel at the head of every street, and your high place you have made in every square; and you have not acted like a prostitute, increasing your price. LXX: What shall I do to your heart, says the Lord God, when you do all these works of a prostitute and shameless woman? ÷ And you have committed adultery three times with your daughters ** when you built your brothel at the beginning of every street, and you made your platform in every square; and you have not been like a prostitute gathering wages. And what the Seventy said: 'And you have prostituted yourself thrice with your daughters, which is not found in the Hebrew, nor has any other Interpreter put it.' But God speaks all of this contentiously towards Jerusalem, that He may find a remedy by which He can heal the sick and the half-dead; according to that which Isaiah writes: 'What more could I have done for my vineyard, that I have not done for it?' (Isaiah 5:4). And Hosea said: What shall I do with you, Ephraim? what shall I do with you, Judah? Your mercy is like the morning clouds, and like the dew in the morning that passes away (Hosea 6:4). For your idolatry is not hidden, but committed with complete freedom, as you set up altars and high places at the beginning of every street and on every corner, and you make your bed in every square. And you have not imitated the cunning of prostitutes, who often increase the price of desire with difficulty, and from this incite lovers to madness. Or according to the Septuagint: You were not like a prostitute gathering wages, but you gave what you should have received, so that you would not be protected by the help of those with whom you fornicated and followed demons, but rather, oppressed by various captivities, you would feel your calamities. And this can indeed be applied to every Christian soul, which, having abandoned the worship of God, has given itself over to vices and luxury, and pursuing a worldly life, did not even thrive in it, but lost the riches of religion and did not receive the riches of the world. And there was no difficulty at all in prostituting yourself to it, but you yourself embraced your lovers. Moreover, there is another spiritual fornication, when we forsake the Church and join the heretics, and build our brothel at the head of every road, as the divine word commands: Stand in the ways and see, and ask for the ancient paths, where the good way is, and walk in it (Jeremiah 6:16), namely in the books of Moses, Joshua, Judges, Kings, Isaiah, Jeremiah, and the other prophets. In the beginnings of all roads, their brothel is constructed, which, to the perversion of doctrine, abuses the testimonies of the Scriptures and says: This is what Isaiah says, this is what Hosea says, this is what Moses said, this is what Daniel said. And he does not place his brothel in the middle of the streets or at the ends of the roads, but at the beginning. For if he comes to knowledge and the depths of divine books, he will not be able to err. He also makes his high place or pedestal in every public square, allowing himself to be corrupted by the depravity and vices of the heathens, even among the heretics when he has been defiled by them, having no grace but exposing himself to contempt, because he easily lost the purity of faith that has passed. But this, which (as we have said above) is not found in Hebrew: Thou art fornicated threefold in thy daughters, or to Jerusalem, according to the letter, that in all kinds in its towns and villages it has fornicated; and there will be no corner or square left, where it has not set up the signs of idolatry: or to the Church and the deceived believers, who have not heard the words of the Apostle: Now may the God of peace Himself sanctify you in all things, that your whole spirit, and soul, and body may be preserved blameless in the coming of our Lord Jesus Christ (1 Thess. V, 23); but they have fornicated in every kind, with body, and soul, and spirit. We read in Proverbs: But you write them in three ways, so that you may answer with words of truth that are proposed to you (Prov. XXII, 20, 21). And it is commanded to us that we understand the words of truth, that is, the holy Scriptures, in three ways. First, according to the letter; second, in the middle through tropology; third, in a higher way, so that we may understand mystical things. According to the letter, it is this: Neither let us commit fornication, as some of them committed fornication, and one and twenty thousand fell in one day (I Cor. X, 8). And: Do not murmur, as some of them murmured and were destroyed by the destroyer (1 Corinthians 10:10). But according to the sense and tropology, when we depart from the literal meaning and ascend a little to higher things, as the Apostle says: It is written: You shall not muzzle the ox when it treads out the grain. And immediately follows: Is God concerned with oxen? Or is He speaking because of us? (1 Corinthians 9:9). But the highest and sublime spiritual understanding, according to the same Apostle: Therefore a man shall leave his father and mother, and be joined to his wife. This is a great mystery. But I speak concerning Christ and the Church (Ephes. 5:31-32). The daughters of the Church are those who fornicate, first of the believers, and afterwards of the deceived in the heresy of the soul, whose fault is attributed to the mother.”
