Jeremiah describes a religious establishment that seeks to serve the establishment of rich, powerful, privileged, and decadent rather than God and people.

The rich and powerful are people too, but must be stripped of the false presumptions of privilege and right-to-rule in order to stand with the poor in the feeding line of mercy and grace.

Religion does not exist to reinforce the decadence of society or keep the boat of oppressive wealth from rocking.

God appoints prophets to comfort the afflicted and afflict the comfortable.

Jeremiah was such a prophet, contrasting with the ethos of the court prophets of his day who told rulers what they wanted to hear.

Jeremiah 23:9-15:
Concerning the prophets: My heart is crushed within me, all my bones shake; I have become like a drunkard, like one overcome by wine, because of the LORD and because of his holy words. For the land is full of adulterers; because of the curse the land mourns, and the pastures of the wilderness are dried up. Their course has been evil, and their might is not right. Both prophet and priest are ungodly; even in my house I have found their wickedness, says the LORD. Therefore their way shall be to them like slippery paths in the darkness, into which they shall be driven and fall; for I will bring disaster upon them in the year of their punishment, says the LORD. In the prophets of Samaria I saw a disgusting thing: they prophesied by Baal and led my people Israel astray. But in the prophets of Jerusalem I have seen a more shocking thing: they commit adultery and walk in lies; they strengthen the hands of evildoers, so that no one turns from wickedness; all of them have become like Sodom to me, and its inhabitants like Gomorrah. Therefore thus says the LORD of hosts concerning the prophets: "I am going to make them eat wormwood, and give them poisoned water to drink; for from the prophets of Jerusalem ungodliness has spread throughout the land."
