Generally, this book is a reflection of the relationship between religion and theater. Particularly, it looks at the relationship of Catholicism and performance or the embodied world of theater in opposition to the written text. In investigating this relationship, two inquiries are identified. First, it is proposed that performance may be looked at as an analogy for the understanding of Catholicism. Second, the link between Catholicism and performance is ontological. In other words, this book is an inquiry on Catholicism “as” a performance and an assertion that it “is” a performance. To illustrate the as/is in the relationship of Catholicism and performance, three Catholic rituals or cultural performances in the province of Pampanga are used as examples: pamamaku king krus, libad nang Apung Iru, and kuraldal nang Apung Lucia.
