I agree with you.... but I think churches that accept homosexuality, abortion, progressiveness... these are symptoms of the disease. Not the disease. The disease is these churches are filled with tares. With persons who don’t truly know Christ. They’re filled with gossip, lies, class envy, pharisees, hypocrisy, and unrepentant sin. These lead to the symptoms you described.
Jeremiah 23...it starts with the pastors. If they will not stand up to false teachers, the church will be full of tares.
