66 And since we have explained the passages of Scripture which are cited against us, we must reply also concerning the Fathers. We are not ignorant that the Mass is called by the Fathers a sacrifice; but they do not mean that the Mass confers grace ex opere operato, and that, when applied on behalf of others, it merits for them the remission of sins, of guilt and punishment. Where are such monstrous stories to be found in the Fathers? But they openly testify that they are speaking of thanksgiving. Accordingly they call it a eucharist.

67 We have said above, however, that a eucharistic sacrifice does not merit reconciliation, but is made by those who have been reconciled, just as afflictions do not merit reconciliation, but are eucharistic sacrifices when those who have been reconciled endure them. And this reply, in general, to the sayings of the Fathers defends us sufficiently against the adversaries. For it is certain that these figments concerning the merit of the opus operatum are found nowhere in the Fathers. But in order that the whole case may be the better understood, we also shall state those things concerning the use of the Sacrament which actually harmonize with the Fathers and Scripture.
