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.
