Coerced by the unvarying as well as unequivocal testimony of our writers, our liturgies, our canons, Usher was obliged to admit that the ancient Irish had been in the constant practice of offering up the eucharistic sacrifice, and that Masses, termed _Requiem Masses_, used to be celebrated daily. So interwoven is the doctrine of the eucharistic sacrifice with the records of the nation, that the antiquarian himself should reject the antiquities of Ireland if he had ventured on the denial of this practice .... Admitting the practice of the ancient Irish Church, Usher strives to escape from the difficulty, as well as attempts to deceive his readers, by pretending that it had been only a sacrifice of thanksgiving, offered as such for those souls who were in possession of eternal happiness, and that it had not been believed or practiced in the ancient Irish Church as a propitiatory sacrifice. .... The ancient canons of the Irish Church as clearly point out as the firmament demonstrates the glory of God, the doctrine of our Church regarding the eucharistic sacrifice, as one of thanksgiving, and also one of propitiation. In an ancient canon contained in D'Achery's collection (lib. 2, cap. 20), the synod says: "The Church offers for the souls of the deceased in four ways--for the very good, the oblations are simply thanksgiving; for the very bad, they become consolations to the living; for such as were not very good, the oblations are made in order to obtain full remission; and for those who were not very bad, that their punishment may be rendered more tolerable." Here, then, is enunciated in plain terms, the doctrine of the eucharistic oblation being a propitiatory sacrifice. When offered for the first class of happy souls, it is an offering of thanksgiving. When offered for those whose lives were bad in the sight of Heaven, its oblation is a comfort to the faithful. When offered for those who were not very good or very bad, the object of its oblation was to render their state more tolerable, and that full pardon would be at length accorded. The framers of this canon give us also the doctrine of a middle state, as a tenet also believed by the Church of Ireland. Another canon, still more ancient, and which is reckoned among those of St. Patrick, is entitled "Of the Oblation for the Dead." This canon is couched in the following words: "There is a sin unto death, I do not say that for it any do pray." This sin is final impenitence.
