While thus the Small Catechism in chart form was completed and published before the Large Catechism, the former succeeded the latter in book form. However, though completed after the Small Catechism, it can be shown that the beginning and perhaps even part of the printing of the Large Catechism dates back to 1528, thus preceding in this respect even the Charts of January 9. If the short Preface to the Large Catechism, as well as the exhortation at the beginning: "Let the young people also come to the preaching, that they hear it explained and learn to understand it," etc., had been written after the 9th of January, Luther would probably have mentioned the Tables, just as he refers to the Large Catechism in the Preface to the Small Catechism, which was written about the end of April or the beginning of May. (535, 17.) Since, however, Luther makes no such indication, these paragraphs of the Large Catechism were, no doubt, composed before January, 1529. (575, 1; 579, 26.) The same inference may be drawn from the fact that, in the explanation of the First Commandment, the wording of the conclusion of the Ten Commandments shows a number of variations from its wording in the Small Catechism, whereas its wording at the close of the explanation of the commandments is in conformity with it. (588, 30; 672, 320.) 102. Similarity and Purpose of Catechisms. As great as is the dissimilarity between Luther's two Catechisms, on the one hand, so great, on the other, is the similarity. If one did not know that the Large Catechism was begun before the Small, and that both originated in the sermons of 1528, he might either view the Large Catechism as a subsequent expansion of the Small, or the latter as a summary of the former. Yet neither the one nor the other is the case. If the Large Catechism influenced the Small, so also the latter the former. Albrecht says: "It is more probable that the Small Catechism influenced the Large Catechism than _vice versa._" (W. 30, 1, 558.) At all events, the second table-series could not have been extracted from the Large Catechism as such, since the latter was only completed after March 25, whereas these tables were published already on March 16. The Small Catechism has been characterized as "a small basketful of ripe fruit gathered from that tree" [the Large Catechism]. In substance that is true, since both originate from the same source, the sermons of 1528. Already Roerer calls attention to this similarity, when in the aforementioned letter, he designates the Large Catechism as "_Catechismus per D. M. praedicatus,_" and then describes the Small Catechism as "_tabulae complectentes brevisissime simul et crasse catechismum Lutheri pro pueris et familia._" Both treat of the same five chief parts; the explanation of both presupposes the knowledge of the text of these parts, both owe their origin to the doctrinal ignorance, uncovered particularly in the Saxon visitation; and the purpose of both
