And then there’s that.
My uncle and his entire family go to some church that has a name like “The church of Jesus Christ, social redeemer” or some crazy crap like that. Its pure communism behind a cross.
A "church" doesn't have to have a name like that. The constituents of all the major denominations are attending assemblies where the major indoctrination is in the "social gospel" and in "social justice" which is exactly what you say. Their communicants are not believing in defeat of sin in their lives by conviction, deep godly sorrow, confession, repentance, and new birth in the realm of the Spirit; and separation from phony religion.
Declaring association with Christ without becoming dead to self, sin as a master, and the world characterizes the message of such denominations.
