And the Fathers, indeed, speak of a twofold effect, of the comfort of consciences, and of thanksgiving, or praise. The former of these effects pertains to the nature [the right use] of the Sacrament; the latter pertains to the sacrifice. Of consolation Ambrose says: Go to Him and be absolved, because He is the remission of sins. Do you ask who He is? Hear Him when He says, John 6, 35: I am the Bread of life; he that cometh to Me shall never hunger; and he that believeth on Me shall never thirst. This passage testifies that in the Sacrament the remission of sins is offered; it also testifies that this ought to be received by faith. Infinite testimonies to this effect are found in the Fathers, all of which the adversaries pervert to the _opus operatum_, and to a work to be applied on behalf of others; although the Fathers clearly require faith, and speak of the consolation belonging to every one, and not of the application. Besides these, expressions are also found concerning thanksgiving, such as that most beautifully said by Cyprian concerning those communing in a godly way. Piety, says he, in thanksgiving the Bestower of such abundant blessing, makes a distinction between what has been given and what has been forgiven, i.e., piety regards both what has been given and what has been forgiven, i.e., it compares the greatness of God's blessings and the greatness of our evils, sin and death, with each other, and gives thanks, etc. And hence the term eucharist arose in the Church. Nor indeed is the ceremony itself, the giving of thanks ex opere operato, to be applied on behalf of others, in order to merit for them the remission of sins, etc., in order to liberate the souls of the dead. These things conflict with the righteousness of faith, as though, without faith, a ceremony can profit either the one performing it or others. Part 33 _Of the Term Mass._
