>>and quit their former course of living<<
Kinda hard to do when you've brought them into the church by using the same things that are in their current course of living.
The Church is to be set apart and sanctified as a holy place. A place for worshipping the Lord in reverence and awe. Not a discotheque/bookstore/coffeehouse/club house/arcade.
You can't call people out of the world by using worldly means. It's like trying to hold an AA meeting at a bar.
How do you explain all the Christians who have been saved under these "seeker friendly" ministries? Are they all goats? Are they all tares?
Do you have a Bible verse that says that? Sola Scriptura. Help me out here.
And when did "the Church" become "a place?"
