This paper selects three aspects of consumerism (individualism, the chronically reinvented self, and viewing nearly everything as a product or commodity) and assesses how they pose a challenge to liturgical worship, which is properly grounded in a Christian indentity that is fundamentally communal. When consumerism takes the form of shopping for a parish, it threatens to undermine this communal identity. At the same time, parish-shopping may well be an expression of a sincere search for a vital Christian community. This paper thus neither condemns nor condones parish shopping but stresses rather that there is work to be done to build up the sense of community in Roman Catholic parishes. Liturgical worship is an essential element in that process, but liturgy by itself cannot build or sustain community.
