Opponents of wreckovation also charge that such changes are iconoclastic and produce results that look more like Protestant churches, theaters, airport terminals, or barns rather than Catholic churches. A major concern is that the design of renovated churches downplays the sense of the sacred in favor of focus on the congregation. Critics see this as inconsistent with the traditional Catholic understanding of communal worship. Meanwhile, more liberal Catholics have referred to the renovations as necessary steps in order to emphasise the role of the congregation in worship in accord with the wishes of the Second Vatican Council. Conservative Catholics charge that this is a misinterpretation of the documents of Vatican II.
