Prayer of consecration said over bread and wine at the eucharist. The BCP uses the title "The Great Thanksgiving" as a major subheading in bold typeface for both eucharistic rites (BCP, pp. 333, 361), thus recovering one of the ancient designations for the eucharistic prayer. See Eucharistic Prayer.
