The first part of the Eucharistic prayers (Anaphora or Canon) in all rites, now separated from the rest by the singing of the “Sanctus”. HISTORY. — According to the idea of thanksgiving which, after the example of the Last Supper (Matt., xxvi, 27; Mark, xiv, 23; Luke xxii, 17, 19; I Cor., xi, 24). forms a fundamental element of the Eucharistic service, all liturgies begin the Anaphora, the consecration-prayer, by thanking God for His benefits. Almost every account we have of the early liturgy mentions this (Didache ix, 2-3; x, 2-4; xiv, 1; Justin “I Apol.” LXV, iii, 5; LXVII, v). Clement of Rome quotes a long example of such a thanksgiving-prayer (I Cor., lx-lxi). So prominent was this idea that it has supplied the usual name for the whole service (Eucharist, eucharistia ). The thanksgiving-prayer enumerated the benefits for which we thank God, beginning generally with the creation, continuing through the orders of nature and grace, mentioning much of Old Testament history, and so coming to the culminating benefit of Christ’s Incarnation, His Life and Passion, in which the story of the Last Supper brings us naturally to the words of institution. In most of the earliest liturgies this enumeration is of considerable length (e.g. Apost. Const., VIII; XII, iv-xxxix; Alexandria, see Brightman, infra , 125-33; Antioch, ibid., 50-2). It is invariably preceded by an invitation to the people: “Lift up your hearts”, and then: “Let us give thanks to the Lord”, or some such formula. The people having answered: “It is right and just”, the celebrant continues, taking up their word: “It is truly right and just first of all to praise [or to thank] thee”; and so the thanksgiving begins.
