Of the Wittenberg editions which followed the _editio princeps,_ those of 1529, 1531, and 1542 deserve special mention. The first appeared under the title: "Enchiridion. The Small Catechism for the Ordinary Pastors and Preachers, enlarged and improved." On the 13th of June this edition was completed, for Roerer reports on this date: "Parvus Catechismus sub iucudem iam tertio revocatus est et in ista postrema editione adauctus." (Kolde _l.c._, 60.) Roerer designates this edition as the third, probably because two imprints had been made of the _editio princeps._ According to a defective copy, the only one preserved, this edition adds to the contents of the _editio princeps_ the word Enchiridion in the title, the Booklet of Baptism, A Brief Form of Confessing to the Priest, for the Simple, and the Litany. The fifth chief part has the question: "How can bodily eating and drinking do such great things?" In the Lord's Prayer, however, the explanation of the introduction is still lacking. This emended edition of 1529 furthermore had the pictures, for the first time as it seems. The booklets on Marriage and Baptism were retained, as additions, in all editions of the Small Catechism published during the life of Luther, and in many later editions as well. As yet, however, it has not been proved directly that such was intended and arranged for by Luther himself. Also in the succeeding editions Luther made various material and linguistic changes. In the edition of 1531 he omitted the Litany, and for the "Short Form of Confession" he substituted an instruction in confession, which he inserted between the fourth and fifth chief parts, under the caption, "How the Unlearned Shall be Taught to Confess." The Lord's Prayer was complemented by the addition of the Introduction and its explanation, and the number of cuts was increased to 23. This edition of 1531, of which but one copy (found in the Bodleiana of Oxford) is in existence, shows essentially the form in which the Enchiridion was henceforth regularly printed during and after Luther's life. (W. 30, 1, 608.) The editions of 1537 reveal several changes in language, especially in the Bible-verses, which are made to conform to Luther's translation. In the edition of 1542 the promise of the Fourth Commandment appears for the first time, and the Table of Duties is expanded. The Bible-verses referring to the relation of congregations to their pastors were added, and the verses setting forth the relation of subjects to their government were considerably augmented. Hence the title: "Newly revised and prepared, _aufs neue uebersehen und zugerichtet._" Probably the last edition to appear during Luther's life was the one of 1543, which, however, was essentially a reprint of the edition of 1542.
