Most of the market-driven megachurches insist they would never compromise doctrine. They are attractive to evangelicals precisely became they claim to be as orthodox in their doctrine as they are unorthodox in their methodology. Multitudes are sufficiently reassured by such promises and simply abandon their critical faculties, thus increasing their vulnerability. Unfortunately, real discernment is in short supply among modern evangelicals.
