In an essay appearing in Sacrality and Materiality: Locating Intersections (Vandenhoeck & Ruprecht, 2016), Claire Wolfteich proposes to expand scholarship in spirituality beyond the more common approach of studying texts to exploring spiritual practices. She writes

I will address the theme of materiality and sacrality from the perspective of practical theology and spirituality studies. Spirituality scholarship has yet to address fully the important to turn to practice, lived religion, and material religion – as noted, for example, by Arthur Holder’s critique of the dominance of spiritual “classics” texts as focus of study within the field.* . . . Practical theology, on the other hand, clearly makes “practice” a central category of theological inquiry and embraces empirical research to unfold local, everyday, embodied religion. . . . I argue for the study of everyday, embodied practices such as work and mothering as important foci for the study of Christian spirituality while also advancing a conception of mystical practical theology that leaves space for the unspeakable sacred.
