He even expressed the opinion that catechetical instruction in church was of little use to children, but that in the home it was more successful and was therefore not to be omitted, however much trouble it might give. When, however, he adds, that the Papists had neglected such home teaching and had sacrificed the flock of Christ,[797] he is quite wrong. The fact is, that, before his day, it was left far too much to the family to give religious instruction to the children, there being as yet no properly organised Catechism in schools and churches. It was only the opposition aroused among Catholics by the religious changes that led to religious teaching becoming more widespread in the Catholic schools, and to a catechetical system being organised; a fuller religious education then served to check the falling away.[798] How highly, in spite of such apparent depreciation, he valued the ministerial teaching of the Catechism we learn from some words recorded by Mathesius: “If I had to establish order, I should see that no preacher was nominated who had not previously taught the ‘_bonæ artes_’ and the Catechism in the schools for from one to three years. Schools are also temples of God, hence the olden prophets were at once pastors and schoolmasters.”[799] “There is no better way,” he writes, “of keeping people devout and faithful to the Church than by the Catechism.”[800] At Wittenberg an arrangement existed, at any rate as early as 1528,[801] by which, every quarter, certain days were set apart for special sermons on the articles of the Catechism.[802] The Larger and the Smaller Catechism published by Luther (see vol. v., xxxiv., 2) were intended to form the basis of the verbal teaching everywhere. The three courses of sermons preached by Luther at Wittenberg in May, Sep. and Nov., 1528, and since edited by George Buchwald, were arranged to suit the contents of the Greater Catechism and to some extent served Luther as a preparation for this publication. Luther, in the first instance, brought out the Smaller Catechism, as we see from certain letters given by Buchwald, not in book form, but, agreeably with an earlier ecclesiastical practice, on separate sheets in the shape of tablets to hang upon the walls; hence what he said on Dec. 18, 1537, of his being the author of the Catechism, the “_tabulæ_” and the Confession of Augsburg.[803]
