As we’ve seen non-denominational churches and their desire to distance themselves from and demonize religion but this very act establishes the existence of a religion (the unique expression of their faith) within their ranks. Think of Crossroads or the Vineyard without coffee or wifi. It has become part of how they express their faith.
This is the same with the left shouting about legalism. They have become legalistic in their determinations and misunderstanding of moral truth labeling it as rigid legalism.
