1. Omitting the various significations of the word "Mass" which may be adduced, we consider, on this occasion, that which the papists declare to be the external and properly called "expiatory sacrifice," in which the sacrificers offer Christ to his Father in behalf of the living and the dead, and which they affirm to have been celebrated and instituted by Christ himself when he celebrated and instituted his last supper.
2. First. We say, this sacrifice is falsely ascribed to the institution of the Lord’s supper; for Christ did not institute a sacrifice, but a sacrament, which is apparent from the institution itself, in which we are not commanded to offer any thing to God, at least nothing external. Yet we grant, that in the Lord’s supper, as in all acts, is commanded, or ought to exist, that internal sacrifice by which believers offer to God prayers, praises and thanksgiving. In this view, the Lord’s supper is called "the eucharist."
3. Secondly. To this sacrifice are opposed the nature, truth and excellence of the sacrifice of Christ. For, as the sacrifice of Christ is single, expiatory, perfect, and of infinite value; and as Christ was once offered, and "hath by that one oblation perfected for ever them who were once sanctified," as the Scriptures testify, undoubtedly no place has been left either for any other sacrifice, or for a repetition of this sacrifice of Christ.
4. Thirdly. Besides, it is wrong to suppose that Christ can be or ought to be offered by men, or by any other person than by himself; for he, alone, is both the victim and the priest, as being the only one who is truly "holy, harmless, undefiled, and separate from sinners."
5. From all these particulars it is sufficiently apparent, that it is not necessary, nay, that it is impious, for any expiatory sacrifice now to be offered by men for the living and the dead. Besides, it is a piece of foolish ignorance, to suppose either that the dead require some oblation; or that they can by it obtain remission of sins, who have not obtained pardon before death.
6. In addition to these three enormous errors committed in the mass, with respect to the sacrifice, to the priest, and to those for whom the sacrifice is offered, there is a fourth, which is one of the greatest turpitude of all, and is committed in conjunction with idolatry — that this very sacrifice is adored by him who offers it, and by those for whom it is offered, and is carried about in solemn pomp.
COROLLARY
In these words, "the mass is an expiatory, representative and commemorative sacrifice," there is an opposition in the apposition and a manifest contradiction.
