This is from a protestant (non-Catholic, non-orthodox I believe anyway), full quote:
"The devil is not fighting religion. He's too smart for that. He is producing a counterfeit Christianity, so much like the real one that good Christians are afraid to speak out against it." -Vance Havner, who died in 1986
(Personal analysis of quote in comments)
The NT epistles talk a lot about it so we have lots of good words on the topic.
Church leadership must preach the whole counsel of God unapologetically without compromising on the truth. The rest of the church needs to root out divisiveness. We need to clear distinctions between serious issues like sin and divisiveness and issues of freedom and opinion so we expend energy on the important issues. We need not fight over matters of opinion.
Giving people the whole, unadulterated truth would be detrimental to their pockets and pews. People want to have their ears tickled, not be convicted of their wrongs, exposed or corrected. They don't want to leave their gods behind when their counterfeit Christ allows them to retain them.
The churches that you think are churches are not the bride. The whole problem here is that people don't realize or want to hear that half of everything they've believed about God is a sham. Christianity is not legitimate in the sight of Christ. That's not a matter of opinion.
Just like everything else corrupted and empowered by the Old Guard, it's about control, money, influence and power.
