Moreover, this godless opinion concerning works always has existed in the world [sticks to the world quite tightly]. The heathen had sacrifices, derived from the fathers. They imitated their works. Their faith they did not retain, but thought that the works were a propitiation and price on account of which God would be reconciled to them. The people in the law [the Israelites] imitated sacrifices with the opinion that by means of these works they would appease God, so to say, _ex opere operato_. We see here how earnestly the prophets rebuke the people: Ps. 50, 8: I will not reprove thee for thy sacrifices, and Jer. 7, 22: I spake not unto your fathers concerning burnt offerings. Such passages condemn not works, which God certainly had commanded as outward exercises in this government, but they condemn the godless opinion according to which they thought that by these works they appeased the wrath of God, and thus cast away faith. And because no works pacify the conscience, new works, in addition to God's commands, were from time to time devised [the hypocrites nevertheless used to invent one work after another, one sacrifice after another, by a blind guess and in reckless wantonness, and all this without the word and command of God, with wicked conscience as we have seen in the Papacy]. The people of Israel had seen the prophets sacrificing on high places [and in groves]. Besides, the examples of the saints very greatly move the minds of those, hoping by similar works to obtain grace just as these saints obtained it. [But the saints believed.] Wherefore the people began, with remarkable zeal, to imitate this work, in order that by such a work [they might appease the wrath of God] they might merit remission of sins, grace, and righteousness. But the prophets had been sacrificing on high places, not that by these works they might merit the remission of sins and grace, but because on these places they taught, and, accordingly, presented there a testimony of their faith. The people had heard that Abraham had sacrificed his son. Wherefore they also, in order to appease God by a most cruel and difficult work, put to death their sons. But Abraham did not sacrifice his son with the opinion that this work was a price and propitiatory work for the sake of which he was accounted righteous. Thus in the Church the Lord's Supper was instituted that by remembrance of the promises of Christ, of which we are admonished in this sign, faith might be strengthened in us, and we might publicly confess our faith, and proclaim the benefits of Christ, as Paul says, 1 Cor. 11, 26: As often as ye eat this bread and drink this cup, ye do show the Lord's death, etc. But our adversaries contend that the mass is a work that justifies us _ex opere operato_, and removes the guilt and liability to punishment in those for whom it is celebrated, for thus writes Gabriel.
