Research
Father Pivranik's primary area of research is in postmodern Sacramental Theology. This increasingly means that one has to have a thorough understanding of early Christian sources, the sacramental deliberations of the Scholastics, and the vision and reform of the Second Vatican Council in order to piece back together a theology of sacraments that satisfies the fractured nature of postmodern research. The goal of Fr. Pivarnik's research has been the development of a definitively Trinitarian method for sacramentology and liturgical participation. While most sacramental studies highlight the role and action of Christ, the conciliar reform and the theology that emanated from it have increasingly called for a deeper Trinitarian understanding of sacramental operation in the West. To that end, his first book, scheduled to be published in 2012 will center on that topic: Toward a TrinitarianTheology of Liturgical Participation (The Liturgical Press).
