The meaning of this term, however, is not always the same. It may designate the act of instructing, the subject-matter or the doctrine imparted, a summary thereof, the text of the traditional chief parts, or a book containing the catechismal doctrine, text, or text with explanation. Luther used the word most frequently and preferably in the sense of instruction. This appears from the definitions quoted in the preceding paragraph, where catechism is defined as "sermon," "instruction," "Christian training," etc. "You have the catechism" (the doctrine), says Luther, "in small and large books." Bugenhagen defines thus: "Katechismus, dat is, christlike underrichtinge ut den teyn gebaden Gades." In the Apology, Melanchthon employs the word catechism as identical with kathechesis puerorum, instruction of the young in the Christian fundamentals. (324, 41.) "Accordingly," says O. Albrecht, "catechism means elementary instruction in Christianity, conceived, first, as the act; then, as the material for instruction; then, as the contents of a book, and finally, as the book itself." This usage must be borne in mind also where Luther speaks of his own Catechisms. "German Catechism" means instruction in, or preaching on, the traditional chief parts in the German language. And while "Enchiridion" signifies a book of small compass, the title "Small Catechism" (as appears from the old subtitle: "Ein kleiner Katechismus oder christliche Zucht") means instruction in the chief parts, proceeding with compact brevity, and, at the same time, these parts themselves together with the explanations added. (W. 30, 1, 454. 539.) As the title of a book the word catechism was first employed by Althamer in 1528, and by Brenz as the subtitle of his "Questions" (Fragestuecke). A school-book written by John Colet in the beginning of the sixteenth century bears the title "Catechyzon, The Instructor." (456.)
Not every kind of Christian instruction, however, is called catechism by Luther. Whenever he uses the word, he has in mind beginners, children, and unlearned people. In his "German Order of Worship, Deutsche Messe," of 1526, he writes: "Catechism is an instruction whereby heathen who desire to become Christians are taught and shown what they must believe, do, not do, and know in Christianity, hence the name catechumens was given to pupils who were accepted for such instruction and who learned the Creed previous to their baptism." (19, 76.) In his sermon of November 30, 1528: "The Catechism is a sermon for children, which the children and all who desire to be Christians must know. Whoever does not know it cannot be numbered among the Christians. For if he does not know these things, it is evident that God and Christ mean nothing to him." (30, 1, 57.) In his sermon of September 14: "This [catechism] is preaching for children, or, the Bible of the laity, which serves the plain people. Whoever, then, does not know these things, and is unable to recite them and understand them, cannot be considered a Christian. It is for this reason, too, that it bears the name catechism, i.e., instruction and Christian teaching, since all Christians at the very least should know this much. Afterward they ought to learn more of the Scriptures. Hence, let all children govern themselves accordingly, and see that they learn it." (27.) May 18 Luther began his sermon thus: "The preaching of the Catechism was begun that it might serve as an instruction for children and the unlearned. … For every Christian must necessarily know the Catechism. Whoever does not know it cannot be numbered among the Christians." (2.) In the short Preface to the Large Catechism: "This sermon is designed and undertaken that it might be an instruction for children and the simpleminded. Hence, of old it was called in Greek catechism, i.e., instruction for children, what every Christian must needs know, so that he who does not know this could not be numbered with the Christians nor be admitted to any Sacrament." (CONC. TRIGL., 575, 1; 535, 11.)
83. Chief Parts of Catechism.
In Luther's opinion the elementary doctrines which form the subject- matter of the Catechism are comprised in the three traditional parts: Decalog, Creed, and Lord's Prayer. These he considered to be the gist of the doctrine every one must learn if he would be regarded and treated as a Christian. "Those who are unwilling to learn it," says Luther, "should be told that they deny Christ and are no Christians; neither should they be admitted to the Sacraments, accepted as sponsors at Baptism, nor exercise any part of Christian liberty." (CONC. TRIGL. 535, 11.) Of course, Luther considered these three parts only a minimum, which, however, Christians who partake of the Lord's Supper should strive to exceed, but still sufficient for children and plain people. (575, 5.) Even in his later years, Luther speaks of the first three parts as the Catechism proper.
However, probably in consequence of the controversy with the Enthusiasts, which began in 1524, Luther soon added as supplements the parts treating of Baptism, the Lord's Supper, and Confession. In the Large Catechism, where Baptism and the Lord's Supper appear as appendices, Luther emphasizes the fact that the first three parts form the kernel of the Catechism, but that instruction in Baptism and the Lord's Supper must also be imparted. "These" (first three), says he, "are the most necessary parts, which one should first learn to repeat word for word. … Now, when these three parts are apprehended, it behooves a person also to know what to say concerning our Sacraments, which Christ Himself instituted, Baptism and the holy body and blood of Christ, namely, the text which Matthew and Mark record at the close of their gospels, when Christ said farewell to His disciples and sent them forth." (579, 20.) Luther regarded a correct knowledge of Baptism and the Lord's Supper not only as useful, but as necessary. Beginning his explanation of the Fourth Chief Part, he remarks: "We have now finished the three chief parts of the common Christian doctrine. Besides these we have yet to speak of our two Sacraments instituted by Christ, of which also every Christian ought to have at least an ordinary, brief instruction, because without them there can be no Christian; although, alas! hitherto no instruction concerning them has been given." (733, 1.) Thus Luther materially enlarged the Catechism. True, several prayer- and confession-books, which appeared in the late Middle Ages, also treat of the Sacraments. As for the people, however, it was considered sufficient for laymen to be able to recite the names of the seven Roman sacraments. Hence Luther, in the passage cited from the Large Catechism, declares that in Popery practically nothing of Baptism and the Lord's Supper was taught, certainly nothing worth while or wholesome.
84. Parts Inherited from Ancient Church.
The text of the first three chief parts, Luther considered a sacred heirloom from the ancient Church. "For," says he in his Large Catechism, "the holy Fathers or apostles have thus embraced in a summary the doctrine life, wisdom, and art of Christians, of which they speak and treat, and with which they are occupied." (579, 19.) Thus Luther, always conservative, did not reject the traditional catechism, both bag and baggage, but carefully distinguished between the good, which he retained, and the worthless, which he discarded. In fact, he no more dreamt of foisting a new doctrine or catechism on the Christian Church than he ever thought of founding a new church. On the contrary, his sole object was to restore the ancient Apostolic Church, and his catechetical endeavors were bent on bringing to light once more, purifying, explaining, and restoring, the old catechism of the fathers.
In his book Wider Hans Worst, 1541, Luther says: "We have remained faithful to the true and ancient Church; aye, we are the true and ancient Church. You Papists, however, have apostatized from us, i.e., from the ancient Church, and have set up a new church in opposition to the ancient Church." In harmony with this view, Luther repeatedly and emphatically asserted that in his Catechism he was merely protecting and guarding an inheritance of the fathers, which he had preserved to the Church by his correct explanation. In his German Order of Worship we read: "I know of no simpler nor better arrangement of this instruction or doctrine than the arrangement which has existed since the beginning of Christendom, viz., the three parts, Ten Commandments, Creed, and the Lord's Prayer." (W. 19, 76.) In the ancient Church the original parts for catechumens and sponsors were the Symbolum and the Paternoster, the Apostles' Creed and the Lord's Prayer. To these the Ten Commandments were added as a formal part of doctrine only since the thirteenth century. (30, 1, 434.) The usual sequence of these parts was: Lord's Prayer, Apostles' Creed, and, wherever it was not supplanted by other matter, the Decalog. It was with deliberation then, that Luther substituted his own objective, logical order.
In his Short Form of the Ten Commandments, the Creed, and the Lord's Prayer, 1520 Luther speaks as follows of the three traditional parts, which God preserved to the Church in spite of the Papacy: "It did not come to pass without the special providence of God, that, with reference to the common Christian, who cannot read the Scriptures, it was commanded to teach and to know the Ten Commandments, Creed, and Lord's Prayer which three parts indeed thoroughly and completely embrace all that is contained in the Scripture and may ever be preached, all also that a Christian needs to know, and this, too, in a form so brief and simple that no one can complain or offer the excuse that it is too much, and that it is too hard for him to remember what is essential to his salvation. For in order to be saved, a man must know three things: First, he must know what he is to do and leave undone. Secondly, when he realizes that by his own strength he is unable to do it and leave it undone, he must know where he may take, seek, and find that which will enable him to do and to refrain. Thirdly, he must know how he may seek and obtain it. Even as a sick man needs first of all to know what disease he has, what he may or may not do, or leave undone. Thereupon he needs to know where the medicine is which will help him, that he may do and leave undone like a healthy person. Fourthly, he must desire it, seek and get it, or have it brought to him. In like manner the commandments teach a man to know his disease, that he may see and perceive what he can do and not do, leave and not leave, and thus perceive that he is a sinner and a wicked man. Thereupon the Creed holds before his eyes and teaches him where to find the medicine, the grace which will help him become pious, that he may keep the commandments, and shows him God and His mercy as revealed and offered in Christ. Fifthly, the Lord's Prayer teaches him how to ask for, get and obtain it, namely, by proper, humble, and comforting prayer. These three things comprise the entire Scriptures." (W. 7, 204.) It was things such as the chief parts of the Catechism that Luther had in mind when he wrote against the fanatics, 1528: "We confess that even under the Papacy there are many Christian blessings aye, all Christian blessings, and thence they have come to us: the true Holy Scriptures, true Baptism, the true Sacrament of the Altar, true keys for the forgiveness of sins, the true office of the ministry, the true catechism, such as the Lord's Prayer, the Ten Commandments the Articles of Faith, etc." (26, 147.) Luther's meaning is, that in the midst of antichristendom and despite the Pope, the text of the three chief parts was, among other things, preserved to the Church.
