This essay is centered around five questions: (i) What is the proper place of liturgical theology? (ii) What past evolutions have there been and what tendencies are there currently in the field of liturgical theology? (iii) What contents should liturgical theologians focus on? (iv) How can liturgical theologians engage in research? And (v): How can liturgical theology appropriately respond to events occurring in Church and society? Each question corresponds to one part. The rationale behind ordering the content this way is the following: starting from a reflection about the non-evident place of liturgical theology, an attempt is made to reposition it on the basis of its genealogy in the Liturgical Movement. It seems that this is a particularly fruitful way to give liturgical theology a proper profile and identity. Correspondingly, liturgical theology can be considered a fully-fledged research program that manifests its usefulness and fruitfulness. In particular, it is shown that liturgical theologians are called to engage in the study of the meaning of Christian worship, and thereby contribute to theology as a whole. They are to employ a variety of methods but should proceed in such a way that directs reflection, research and spirituality always towards the core of liturgy, as established by the history and economy of salvation and culminating in the paschal mystery. If, and inasmuch they do this, they will have a great deal to offer given the complex challenges the Church and theology are confronted with today. The fundamental principle of this entire essay is that liturgical theology does not simply deal with Christian rituals, festivals and sacraments, but with the core of faith itself—God, the world, the Christ event, tradition, Church, and redemption—to the extent that it is embodied and expressed in worship practices.
