12. Now we see how many parts there are in this testament, or the mass. There is, first, the testator who makes the testament, Christ. Second, the heirs to whom the testament is bequeathed, we Christians. Third, the testament in itself, the words of Christ when He says: "This is My body which is given for you. This is My blood which is shed for you, a new eternal testament, etc." Fourth, the seal or token, the sacrament, bread and wine, and under them His true body and blood. For everything that is in this sacrament must live; therefore He did not put it in dead writ and seal, but in living words and signs which we use from day to day.
And this is what is meant when the priest elevates the host,[5] by which act he addresses us rather than God, as though he said to us: Behold, this is the seal and sign of the testament in which Christ has bequeathed us remission of all an and eternal life. With this agrees also that which is sung by the choir: "Blessed be He that cometh to us in the name of God" [Matt. 21:9]?[6] so that we testify how we receive therein blessings from God, and do not sacrifice nor give to Him. Fifth, the bequeathed blessing which the words signify, namely, remission of sin and eternal life. Sixth, the obligation, remembrance or requiem which we should observe for Christ, to wit, that we preach this His love and grace, hear and meditate upon it, by it be incited and preserved unto love and hope in Him, as St. Paul explains it: "As oft as ye eat this bread and drink of this cup ye show the death of Christ." [1 Cor. 11:26] And this is what an earthly testator does, who bequeaths something to his heirs, that he may leave behind him a good name, the good will of men and a blessed memory, that he be not forgotten.
[Sidenote: How the Mass Should be Regarded]
13. From all this it is now easily seen what the mass is, how one should prepare himself for it, how observe and how use it, and how many are the abuses of it. For just as one would act if ten thousand gulden were bequeathed him by a good friend: so, and with far more reason, we ought to conduct ourselves toward the mass, which is nothing else than an exceeding rich and everlasting and good testament bequeathed us by Christ Himself, and bequeathed in such wise that He would have had no other reason to die except that He wished to make such a testament; so fervently desirous was He to pour out His eternal treasures, as He says: "With desire I have desired to eat this passover with you before I die." [Luke 22:15] Hence, too, it comes that in spite of many masses we remain so blind and cold, for we do not know what the mass is, what we do in it, nor what we get from it.
[Sidenote: Faith in the word the True Preparation for the Mass]
Since then it is nothing else than a testament, the first and by far the best preparation for the mass is a hungry soul and a firm joyful faith of the heart accepting such a testament Who would not go with great and joyful desire, hope and comfort, and demand a thousand gulden, if he knew that at a certain place they had been bequeathed him; especially if there were no other condition than that he remember, honor, and praise the testator? So, in this matter, you must above all else take heed to your heart, that you believe the words of Christ, and admit their truth, when He says to you and to all: "This is My blood, a new testament, by which I bequeath you forgiveness of all sins and eternal life." How could you do Him greater dishonor and show greater disrespect to the holy mass than by not believing or by doubting? For He desired this to be so certain that He Himself even died for it. Surely such doubt would be naught else than denying and blaspheming Christ's sufferings and death, and every blessing which He has thereby obtained.
14. For this reason, I have said, everything depends upon the words of this sacrament, which are the words of Christ, and which we verily should set in pure gold and precious stones, and keep nothing more diligently before the eyes of the heart, that faith be exercised thereby. Let another pray, fast, go to confession, prepare himself for mass and the sacrament as he will. Do thou the same, but know that all that is pure fool's-work and self-deception, if you do not set before you the words of the testament and arouse yourself to believe and desire them. A long time would you have to polish your shoes, pick the lint[7] off your clothes, and deck yourself out to get an inheritance, if you had no letter and seal with which you could prove your right to it. But if you have letter and seal, and believe, desire, and seek it, it must be given you, even though you were scaly, scabby, stinking and most unclean. So if you would receive this sacrament and testament worthily, see to it that you bring forward these living words of Christ, rely thereon with a strong faith, and desire what Christ has therein promised you: then it will be given you, then are you worthy and well prepared. This faith and confidence must and will make you joyful, and awaken a bold love for Christ, by means of which you will begin with joy to lead a really good life and with all your heart to flee from sin. For he who loves Christ will surely do what pleases Him, and leave undone what does not please Him. But who will love Him except he taste the riches of this testament which Christ, out of pure mercy, has freely bequeathed to poor sinners? This taste comes by the faith which believes and trusts the testament and promise. If Abraham had not believed the promise of God he would never have amounted to anything. Just as certainly, then, as Abraham, Noah, and David accepted and believed their promises: so certainly must we also accept and believe this testament and promise.
[Sidenote: Who is Worthy]
15. Now there are two temptations which never cease to assail you; the first, that you are entirely unworthy of so rich a testament, the second, that even were you worthy, the blessing is so great that human nature is terrified by the greatness of it; for what do not forgiveness of all sin and eternal life bring with them? If either of these temptations comes to you, you must, as I have said, esteem the words of Christ more than such thoughts. It will not be He that lies to you; your thoughts will be deceiving you.
Just as though a poor beggar, yea, a very knave, were bequeathed a thousand gulden: he would not demand them because of his merit or worthiness, nor fail to claim them because of the greatness of the sum; and if any one should cast up to him his unworthiness and the greatness of the sum, he would certainly not allow anything of that sort to frighten him, but would say: "What is that to you? I know full well that I am unworthy of the inheritance; I do not demand it on my merits, as though it had been due me, but on the favor and grace of the testator. If he did not think it too much to bequeath to me, why should I so despise myself and not claim and take it?" So also must a timid, dejected conscience insist, against its own thoughts, upon the testament of Christ, and be stubborn in firm faith, despite its own unworthiness and the greatness of the blessing. For this very reason that which brings to such unworthy ones so great a blessing is a divine testament, by which God desires above all things to awaken love to Him. So Christ comforted those dejected ones who thought the blessing too great and said: "Faint-hearted little flock, fear not; it hath pleased your Father to give you the eternal Kingdom." [Luke 12:32]
