How does a deeper understanding of eucharistic thanksgiving also nuance and correct the Roman understanding of consecration and sacrifice? For centuries, the Roman Canon was the only Latin eucharistic prayer. Although Roman Catholics now hear a variety of prayers, and the Roman Canon is used infrequently in many parishes, the theological and spiritual paradigm that was built around this prayer still predetermines Roman Catholic eucharistic theology and practice.1 Now that the Canon is balanced by other eucharistic prayers, Latin Christians have a new opportunity to interpret its worldview in conversation with that expressed by other prayers indigenous to other parts of the Christian world.
