The genuine task of liturgical studies and sacramental theology is

  • to systematically collect the liturgical practices of the entire Christian tradition.

 Also, the origin and development

  • of their ritual forms
  • as well as their substance regarding sacramental theology shall be explored.

This helps to understand and explain the existent liturgy/liturgies and their continuous need of reform. 
This leads to

  • the ecumenic and interreligious focus of liturgical studies on the one hand and
  • to its interdisciplinary cooperation, which is urged by its pluralism of methods, with the (especially dogmatic, biblical and pastoral) theological, humanities and social sciences disciplines.
