Thus we have these three parts which it is necessary to know concerning this Sacrament especially that the ordinance of God is to be held in all honor, which alone would be sufficient, though it be an entirely external thing like the commandment, Honor thy father and thy mother, which refers to bodily flesh and blood. Therein we regard not the flesh and blood, but the commandment of God in which they are comprehended, and on account of which the flesh is called father and mother; so also, though we had no more than these words, Go ye and baptize, etc., it would be necessary for us to accept and do it as the ordinance of God. Now there is here not only God's commandment and injunction, but also the promise, on account of which it is still far more glorious than whatever else God has commanded and ordained, and is, in short, so full of consolation and grace that heaven and earth cannot comprehend it. But it requires skill to believe this, for the treasure is not wanting, but this is wanting that men apprehend it and hold it firmly.
Therefore every Christian has enough in Baptism to learn and to practice all his life; for he has always enough to do to believe firmly what it promises and brings: victory over death and the devil, forgiveness of sin, the grace of God, the entire Christ, and the Holy Ghost with His gifts. In short, it is so transcendent that if timid nature could realize it, it might well doubt whether it could be true. For consider, if there were somewhere a physician who understood the art of saving men from dying, or, even though they died, of restoring them speedily to life, so that they would thereafter live forever, how the world would pour in money like snow and rain, so that because of the throng of the rich no one could find access! But here in Baptism there is brought free to every one's door such a treasure and medicine as utterly destroys death and preserves all men alive.
Thus we must regard Baptism and make it profitable to ourselves, that when our sins and conscience oppress us, we strengthen ourselves and take comfort and say: Nevertheless I am baptized; but if I am baptized, it is promised me that I shall be saved and have eternal life, both in soul and body. For that is the reason why these two things are done in Baptism namely, that the body, which can apprehend nothing but the water, is sprinkled, and, in addition, the word is spoken for the soul to apprehend. Now, since both, the water and the Word, are one Baptism, therefore body and soul must be saved and live forever: the soul through the Word which it believes, but the body because it is united with the soul and also apprehends Baptism as it is able to apprehend it. We have, therefore, no greater jewel in body and soul, for by it we are made holy and are saved, which no other kind of life, no work upon earth, can attain.
Let this suffice respecting the nature, blessing, and use of Baptism, for it answers the present purpose.
[Part Fifth.]
OF THE SACRAMENT OF THE ALTAR.
In the same manner as we have heard regarding Holy Baptism, we must speak also concerning the other Sacrament, namely, these three points: What is it? What are its benefits? and, Who is to receive it? And all these are established by the words by which Christ has instituted it, and which every one who desires to be a Christian and go to the Sacrament should know. For it is not our intention to admit to it and to administer it to those who know not what they seek, or why they come. The words, however, are these:
Our Lord Jesus Christ, the same night in which He was betrayed, took bread; and when He had given thanks, He brake it, and gave it to His disciples, and said, Take, eat; this is My body, which is given for you: this do in remembrance of Me.
After the same manner also He took the cup when He had supped, gave thanks, and gave it to them, saying, Drink ye all of it; this cup is the new testament in My blood, which is shed for you for the remission of sins: this do ye, as oft as ye drink it, in remembrance of Me.
Here also we do not wish to enter into controversy and contend with the traducers and blasphemers of this Sacrament, but to learn first (as we did regarding Baptism) what is of the greatest importance, namely that the chief point is the Word and ordinance or command of God. For it has not been invented nor introduced by any man, but without any one's counsel and deliberation it has been instituted by Christ. Therefore, just as the Ten Commandments, the Lord's Prayer, and the Creed retain their nature and worth although you never keep, pray, or believe them, so also does this venerable Sacrament remain undisturbed, so that nothing is detracted or taken from it, even though we employ and dispense it unworthily. What do you think God cares about what we do or believe, so that on that account He should suffer His ordinance to be changed? Why, in all worldly matters every thing remains as God has created and ordered it, no matter how we employ or use it. This must always be urged, for thereby the prating of nearly all the fanatical spirits can be repelled. For they regard the Sacraments, aside from the Word of God, as something that we do.
