Shared ritual practices, multi-faith celebrations, and interreligious prayers are becoming increasingly common in the USA and Europe as more people experience religious diversity first hand. While ritual participation can be seen as a powerful expression of interreligious solidarity, it also carries with it challenges of a particularly sensitive nature. Though celebrating and worshiping together can enhance interreligious relations, cross-riting may also lead some believers to question whether it is appropriate to engage in the rituals of another faith community. Some believers may consider cross-ritual participation as inappropriate transgressive behaviour. Bringing together leading international contributors and voices from a number of religious traditions, Ritual Participation and Interreligious Dialogue delves into the complexities and intricacies of the phenomenon. They ask: what are the promises and perils of celebrating and praying together? What are the limits of ritual participation? How can we make sense of feelings of discomfort when entering the sacred space of another faith community? The first book to focus on the lived dimensions of interreligious dialogue through ritual participation rather than textual or doctrinal issues, this innovative volume opens an entirely new perspective.

In line with a profound theological understanding of liturgy as the Church at prayer (ecclesia orans), the focus of this Element is the variegated ways in which Christians address, turn to, and worship God in their central rituals and celebrations. Surveying a representative sample of official liturgical sources from different Christian Churches, the question is asked how 'pure' the monotheism expressed in them is. For one could argue that there is some ambiguity involved, especially with respect to (i) the peculiar position of Christ, the Son of God, and God the Father in liturgical prayers, and (ii) regarding the veneration of the saints. The essential key to unlock this complex and multi-layered reality is a meticulous study of the essential doxological nature of Christian liturgy, both from a phenomenological point of view and on the basis of fine textual analyses.

Can Christian worship engage our secular culture? Should it? While engaging thinkers in philosophy, history, religious anthropology, and liturgical theology, liturgical theologian Joris Geldhof argues that such engagement is necessary-that our liturgy and faith should embrace our modern culture. He shows that liturgy itself is an immensely resourceful reality that appeals to any human being, regardless of sociocultural and intellectual circumstances. If properly understood, the liturgy can provide a powerful dynamic that helps people overcome any binary, including the unfortunate one between the "left" and "right" within the Catholic Church.

This essay is centered around five questions: (i) What is the proper place of liturgical theology? (ii) Which evolutions have there been in the past and which current tendencies are there in the field of liturgical theology? (iii) Which contents must liturgical theologians focus on? (iv) How can liturgical theologians engage in research? And (v): How can liturgical theology appropriately respond to what happens in Church and society? Each question corresponds with one part. The rationale behind ordering the content of this essay in this way is the following: starting from a reflection about the non-evident place of liturgical theology, an attempt is made to give it a fitting profile again on the basis of its genealogy in the Liturgical Movement. Correspondingly, liturgical theology can be considered a full-fledged research program, which does not simply deal with Christian rituals, festivals and sacraments, but with the core of Christian faith.
