Summary

Liturgical theology studies the meaning of Christian worship. Although it is a relatively recent approach, it is solidly anchored in the Christian tradition. Its present shape, fame, and impact would not be what they are and its major representatives would not be able to do what they are doing without the lasting influence of the Liturgical Movement and some inspiring figures that helped shape its theological profile. Their ideas and writings were widely received beyond linguistic and denominational borders and continue to be influential in the early 21st century. More concretely, the key to comprehending what liturgical theologians do lies in their appeal to and usage of the liturgy, broadly understood as the Church’s ritual, prayer, and worship practices. Therefore, liturgical theology is not so much a subdiscipline corresponding with a specific object of research and requiring a set of specialized methods, but rather a way of theologizing pertaining to the entire scope and content of the Christian faith and religion. Liturgical theologians interpret the liturgy as the normative horizon for any theoretical theological reflection and take the liturgy not as the only but definitely as the primary source for theology. This operational principle is reflected in the age-old adage lex orandi, lex credendi, which in its earliest formulation implies that the “law of faith,” or belief content, is determined, or shaped, by the “law of prayer,” or liturgical praxis. Because liturgical theology is still a field in full development, it faces a lot of challenges for the future—both within the Church and in the academy—but at the same time entails a promising ecumenical potential.
