Hence the only worthy preparation and proper use of the mass is faith in the mass, that is to say, in the divine promise. Whoever, therefore, is minded to approach the altar and to receive the sacrament, let him beware of appearing empty before the Lord God [Ex. 23:15; 34:20]. But he will appear empty unless he has faith in the mass, or this new testament. What godless work that he could commit would be a more grievous crime against the truth of God, than this unbelief of his, by which, as much as in him lies, he convicts God of being a liar and a maker of empty promises? The safest course, therefore, will be to go to mass in the same spirit in which you would go to hear any other promise of God; that is, not to be ready to perform and bring many works, but to believe and receive all that is there promised, or proclaimed by the priest as having been promised to you. If you do not go in this spirit, beware of going at all; you will surely go to your condemnation.

I was right then in saying[59] that the whole power of the mass consists in the words of Christ, in which He testifies that the remission of sins is bestowed on all those who believe that His body is given and His blood shed for them. For this reason nothing is more important for those who go to hear mass than diligently and in full faith to ponder these words. Unless they do this, all else that they do is in vain.

[Sidenote: The External Sign, which is the Sacrament]

But while the mass is the word of Christ, it is also true that God is wont to add to well-nigh every promise of His a certain sign as a mark or memorial of His promise, so that we may thereby the more faithfully hold to His promise and be the more forcibly admonished by it. Thus, to his promise to Noah that He would not again destroy the world by a flood, He added His bow in the clouds, to show that He would be mindful of His covenant [Gen. 9:13]. And after promising Abraham the inheritance in his seed, He gave him the sign of circumcision as the seal of his righteousness by faith. Thus, to Gideon He granted the sign of the dry and the wet fleece, to confirm His promise of victory over the Midianites [Judges 6:36 ff.]. And to Ahaz He offered a sign through Isaiah concerning his victory over the kings of Syria and Samaria, to strengthen his faith in the promise [Isa. 7:10 ff.]. And many such signs of the promises of God do we find in the Scriptures.

Thus also to the mass, that crown of all His promises. He adds His body and blood in the bread and wine, as a memorial sign of this great promise; as He says, "This do in remembrance of me." [1 Cor. 11:24] Even so in baptism He adds to the words of the promise, the sign of immersion in water. We learn from this that in every promise of God two things are presented to us--the word and the sign--so that we are to understand the word to be the testament, but the sign to be the sacrament. Thus, in the mass, the word of Christ is the testament, and the bread and wine are the sacrament. And as there is greater power in the word than in the sign, so there is greater power in the testament than in the sacrament; for a man can have and use the word, or testament, apart from the sign, or sacrament. "Believe," says Augustine, "and thou hast eaten."[60] But what does one believe save the word of promise? Therefore I can hold mass every day, yea, every hour, for I can set the words of Christ before me, and with them refresh and strengthen my faith, as often as I choose. That is a truly spiritual eating and drinking.[61]

Here you may see what great things our theologians of the Sentences[62] have produced. That which is the principal and chief thing, namely, the testament and word of promise, is not treated by one of them; thus they have obliterated faith and the whole power of the mass. But the second part of the mass,--the sign, or sacrament,[63]--this alone do they discuss, yet in such a manner that here too they teach not faith but their preparations and opera operata, participations and fruits[64], as though these were the mass, until they have fallen to babbling of transubstantiation and endless other metaphysical quibbles, and have destroyed the proper understanding and use of both sacrament and testament, altogether abolished faith, and caused Christ's people to forget their God, as the prophet says, days without number [Jer. 2:32]. But do you let the others tell over the manifold fruits of hearing mass, and turn hither your mind, and say and believe with the prophet, that God here prepares a table before you, against all those that afflict you, at which your soul may eat and grow fat [Ps. 23:5]. But your faith is fed only with the word of divine promise, for "not in bread alone doth man live, but in every word that proceedeth from the mouth of God." [Deut. 8:3; Matt. 4:4] Hence, in the mass you must above all things pay closest heed to the word of promise, as to your rich banquet, green pasture, and sacred refreshment; you must esteem this word higher than all else, trust in it above all things, and cling firmly to it even through the midst of death and all sins. By thus doing you will attain not merely to those tiny drops and crumbs of "fruits of the mass," which some have superstitiously imagined, but to the very fountainhead of life, which is faith in the word, from which every blessing flows; as it is said in John iv: "He that believeth in me, out of his belly shall flow rivers of living water" [John 7:38]; and again: "He that shall drink of the water that I will give him, it shall become in him a fountain of living water, springing up into life everlasting." [John 4:14][65]

Now there are two things that commonly tempt us to lose the fruits of the mass: first, the fact that we are sinners and unworthy of such great things because of our exceeding vileness; and, secondly, the act that, even if we were worthy, these things are so high that our faint-hearted nature dare not aspire to them or ever hope to attain to them. For to have God for our Father, to be His sons and heirs of all His goods--these are the great blessings that come to us through the forgiveness of sins and life everlasting. And who that regarded them aright must not rather stand aghast before them than desire to possess them? Against this twofold faintness of ours we must lay hold on the word of Christ and fix our gaze on it much more firmly than on those thoughts of our weakness. For "great are the works of the Lord [Ps. 111:2]; wrought out according to all His wills, who is able to do exceeding abundantly above all that we ask or think." [Eph. 3:20] If they did not surpass our worthiness, our grasp and all our thoughts, they would not be divine. Thus Christ also encourages us when He says: "Fear not, little flock, for it hath pleased your Father to give you a kingdom." [Luke 17:32] For it is just this overflowing goodness of the incomprehensible God, lavished upon us through Christ, that moves us to love Him again with our whole heart above all things, to be drawn to Him with all confidence, to despise all things else, and be ready to suffer all things for Him; wherefore this sacrament is well styled "a fount of love."

Let us take an illustration of this from every day life[66]. If a thousand gulden were bequeathed by a rich lord to a beggar or an unworthy and wicked servant, it is certain that he would boldly claim and take them regardless of his unworthiness and the greatness of the bequest. And if any one should seek to oppose him by casting in his teeth his unworthiness and the large amount of the legacy, what do you suppose he would say? He would say, forsooth: "What is that to you? What I accept, I accept not on my merits or by any right that I may personally have to it; I know that I am unworthy and receive more than I have deserved, nay, I have deserved the very opposite. But I claim it because it is so written in the will, and on the score of another's goodness. If it was not an unworthy thing for him to bequeath so great a sum to an unworthy person, why should I reuse to accept it because of my unworthiness? Nay, the more unworthy I am, the more reason have I to accept this other man's gracious gift." With such thoughts we need to fortify the consciences of men against all qualms and scruples, that they may lay hold on the promise of Christ with unwavering faith, and take the greatest care to approach the sacrament, not trusting in their confession, prayer and preparation, but rather despairing of these and with a proud confidence in Christ Who gives the promise. For, as we have said again and again, the word of promise must here reign supreme in a pure and unalloyed faith, and such faith is the one and all-sufficient preparation.

[Sidenote: The Mass Converted into a Good Work]

Hence we see how angry God is with us, in that he has permitted godless teachers to conceal the words of this testament from us, and thereby, as much as in them lay, to extinguish faith. And the inevitable result of this extinguishing of faith is even now plainly to be seen--namely, the most godless superstition of works. For when faith dies and the word of faith is silent, works and the traditions of works immediately crowd into their place. By them we have been carried away out of our own land, as in a Babylonian captivity, and despoiled of all our precious possessions. This has been the fate of the mass; it has been converted by the teaching of godless men into a good work, which they themselves call an opus operatum[67] and by which they presumptuously imagine themselves all-powerful with God. Thereupon they proceeded to the very height of madness, and having invented the lie that the mass works ex opere operate[68], they asserted further that it is none the less profitable to others, even if it be harmful to the wicked priest celebrating it. On such a foundation of sand they base their applications, participations, sodalities, anniversaries and numberless other money-making schemes.
