In Beyond Ritual

Siobhan Garrigan uses Habermas's theory of communicative action to suggest two things: first, a method by which theology can access the ritual symbols by which faith is formed; and secondly a metaphor of intersubjectivity with which theology can propose an interpretative, rather than an instrumental, understanding of sacramentality - and thus of God.

Through fieldwork studies of both marginal and mainstream Christian Eucharists, Garrigan develops the conversation between Habermas's philosophy and Christian theology, showing how ritual interactions form, and challenge, our very idea of God.
