26. To be sure, this sacrifice of prayer, praise and thanksgiving, and of ourselves, we are not to present before God in our own person, but we are to lay it on Christ and let Him present it, as St. Paul teaches in Hebrews xiii: "Let us offer the sacrifice of praise to God continually, that is, the fruit of the lips which confess Him and praise Him," [Heb. 13:15] and all this through Christ. For He is also a priest, as Psalm cx says: "Thou art a priest forever after the order of Melchizedek" [Ps. 110:4]; because He intercedes for us in heaven, receives our prayer and sacrifice, and through Himself, as a godly priest, makes them pleasing to God [Heb. 5:6, 10, etc.], as St. Paul says again in Hebrews ix: "He is ascended into Heaven to be a mediator in the presence of God for us" [Heb. 9:24]; and: "It is Christ Jesus that died, yea, rather, that is risen again, Who is even at the right hand of God, Who also maketh intercession for us." [Rom. 8:34]

From these words we learn that we do not offer Christ as a sacrifice, but that Christ offers us. And in this way it is permissible, yea, profitable, to call the mass a sacrifice, not on its own account, but because we offer ourselves as a sacrifice along with Christ; that is, we lay ourselves on Christ by a firm faith in His testament, and appear before God with our prayer, praise and sacrifice only through Him and through His mediation; and we do not doubt that He is our priest and minister in heaven before God. Such faith, forsooth, brings it to pass that Christ takes up our cause, presents us, our prayer and praise, and also offers Himself for us in heaven. If the mass were so understood and therefore called a sacrifice, it would be well. Not that we offer the sacrament, but that by our praise, prayer and sacrifice we move Him and give Him occasion to offer Himself for us in heaven, and ourselves with Him. As though I were to say, I had brought a king's son to his father as an offering, when, indeed, I had done no more than induce that son to present my need and petition to the king, and made the son my mediator.

27. Few, however, understand the mass in this way. For they suppose that only the priest offers the mass as a sacrifice before God, although this is done and should be done by everyone who receives the sacrament, yea, also by those who are present at the mass and do not receive the sacrament. Furthermore, such offering of sacrifice every Christian may make, wherever he is and at all times, as St. Paul says: "Let us offer the sacrifice of praise continually through Him," [Heb. 13:15] and Psalm cx: "Thou art a priest forever." [Ps. 110:4] If He is a priest forever, then He is at all times a priest and is offering sacrifices without ceasing before God. But we cannot be continually the same, and therefore the mass has been instituted that we may there come together and offer such sacrifice in common.
But let him who understands the mass otherwise or uses it otherwise than as a testament and sacrifice of this kind take heed how he understands it. I understand it, as has been said, to be really nothing else than this, that we receive the testament and at the same time admonish ourselves and be minded to strengthen our faith and not doubt that Christ is our priest in heaven, who offers Himself for us without ceasing and presents us and our prayer and praise, and makes them acceptable; just as though I were to offer the human priest as a sacrifice in the mass and appoint him to present my need and my praise of God, and he were to give me a token that he would do it. In this case I would be offering the priest as a sacrifice; and it is in this wise that I offer Christ, in that I desire and believe that He accepts me and my prayer and praise, and presents it to God in His own person, and to strengthen this faith, gives me a token that He will do it. This token is the sacrament of bread and wine. Thus it becomes clear that it is not the priest alone who offers the sacrifice of the mass, but every one's faith, which is the true priestly office, through which Christ is offered as a sacrifice to God. This office the priest, with the outward ceremonies of the mass, simply represents. Each and all are, therefore equally spiritual priests before God. [Rev. 1:6; 5:10, 1 Pet. 2:9]
[Sidenote: Faith the True Priestly Office]
28. From this you can see for yourself that there are many who rightly observe mass and make this sacrifice, who themselves know nothing about it, nay, who do not realize that they are priests and can observe mass. Again, there are many who take great pains and apply themselves with all diligence, thinking that they are keeping the mass properly and offering a right sacrifice, and yet there is nothing right about it. For all those who have the faith that Christ is a priest for them in heaven before God, and who lay on Him their prayers and praise, their need and their whole selves, and present them through Him, not doubting that He does this very thing, and offers Himself for them, these take the sacrament and testament, outwardly or spiritually, as a sign of all this, and do not doubt that all sin is thereby forgiven, that God has become their gracious Father and that everlasting life is prepared for them.
All such, then, wherever they may be, are true priests, observe the mass aright and also obtain by it what they desire. For faith must do everything. It alone is the true priestly office and permits no one else to take its place. Therefore all Christians are priests; the men, priests, the women, priestesses, be they young or old, masters or servants, mistresses or maids, learned or unlearned. Here there is no difference, unless faith be unequal. Again, all who do not have such faith, but presume to make much of the mass as a sacrifice, and perform this office before God, are figure-heads. They observe mass outwardly and do not themselves know what they are doing, and cannot be well pleasing to God. For without true faith it is impossible to please Him, as St. Paul says in Hebrews xi. [Heb. 11:6] Now there are many who, hidden in their hearts, have such true faith, and themselves know not of it; many there are who do not have it, and of this, too, they are unaware.
