John MacArthur writes in his book "Ashamed of the Gospel"
"The market-driven philosophy of user-friendly churches does not easily permit them to take firm enough doctrinal positions to oppose false teaching. Their outlook on leadership drives them to hire marketers who can sell rather than biblically qualified pastors who can teach. Their approach to ministry is so undoctrinal that they cannot educate their people against subtle errors. Their avoidance of controversy puts them in a position where they cannot oppose false teaching that masquerades as evangelicalism".
