" In one sense, the “fourth wall” perfectly suits the Age of the Enlightenment and the privilege it accorded to critical distance, abstraction, and neutral observation (i.e., “theory”). However, even in the church there is often a tendency to erect a “fourth wall” between what leaders do at the front of the church and what happens in the congregation. The fourth wall here functions not as a theatrical convention but rather as an obstacle to genuine worship insofar as it cordons off the congregation from the doxological action. "
