Neither does the Greek canon apply the offering as a satisfaction for the dead, because it applies it equally for all the blessed patriarchs, prophets, apostles. It appears therefore that the Greeks make an offering as thanksgiving, and do not apply it as satisfaction for punishments. [For, of course, it is not their intention to deliver the prophets and apostles from purgatory, but only to offer up thanks along and together with them for the exalted eternal blessings that have been given to them and us.] Although they speak, moreover, not of the offering alone of the body and blood of the Lord, but of the other parts of the Mass, namely, prayers and thanksgiving. For after the consecration they pray that it may profit those who partake of it, they do not speak of others. Then they add: _Eti prospheromen soi tehn logikehn tautehn latreian huper tohn en pistei anapausamenohn propatorohn, paterohn, patriarchohn, prophertohn, apostolohn_, etc. ["Yet we offer to you this reasonable service for those having departed in faith, forefathers, fathers, patriarchs prophets, apostles," etc.] Reasonable service, however, does not signify the offering itself, but prayers and all things which are there transacted. Now, as regards the adversaries' citing the Fathers concerning the offering for the dead, we know that the ancients speak of prayer for the dead, which we do not prohibit, but we disapprove of the application _ex opere operato_ of the Lord's Supper on behalf of the dead. Neither do the ancients favor the adversaries concerning the _opus operatum_. And even though they have the testimonies especially of Gregory or the moderns, we oppose to them the most clear and certain Scriptures. And there is a great diversity among the Fathers. They were men, and could err and be deceived. Although if they would now become alive again, and would see their sayings assigned as pretexts for the notorious falsehoods which the adversaries teach concerning the opus operatum, they would interpret themselves far differently.
