I love these little paradigms Driscoll has. They're helpful when attempting to synthesize American Christianity. He explains them all in further detail in his books, but you should get the picture.
Gospel + Church - Culture = FundamentalismCulture + Gospel - Church = ParachurchChurch + Culture - Gospel = Liberalism
Of course, the conclusion to these is that Gospel + Church + Culture = the Kingdom [or biblical Christianity or whatever you'd like to call it]. Read his "Confessions" book. It's insightful and hilarious.
