###Input: Luther devised the catechism as a method of imparting the basics of Christianity to the congregations. In 1529, he wrote the Large Catechism, a manual for pastors and teachers, as well as a synopsis, the Small Catechism, to be memorised by the people themselves. The catechisms provided easy-to-understand instructional and devotional material on the Ten Commandments, the Apostles' Creed, the Lord's Prayer, baptism, and the Lord's Supper. Luther incorporated questions and answers in the catechism so that the basics of Christian faith would not just be learned by rote, "the way monkeys do it", but understood.

The catechism is one of Luther's most personal works. "Regarding the plan to collect my writings in volumes," he wrote, "I am quite cool and not at all eager about it because, roused by a Saturnian hunger, I would rather see them all devoured. For I acknowledge none of them to be really a book of mine, except perhaps the Bondage of the Will and the Catechism." The Small Catechism has earned a reputation as a model of clear religious teaching. It remains in use today, along with Luther's hymns and his translation of the Bible.

Luther's Small Catechism proved especially effective in helping parents teach their children; likewise the Larger Catechism was effective for pastors. Using the German vernacular, they expressed the Apostles' Creed in simpler, more personal, Trinitarian language. He rewrote each article of the Creed to express the character of the Father, the Son, or the Holy Spirit. Luther's goal was to enable the catechumens to see themselves as a personal object of the work of the three persons of the Trinity, each of which works in the catechumen's life. That is, Luther depicted the Trinity not as a doctrine to be learned, but as persons to be known. The Father creates, the Son redeems, and the Spirit sanctifies, a divine unity with separate personalities. Salvation originates with the Father and draws the believer to the Father. Luther's treatment of the Apostles' Creed must be understood in the context of the Decalogue (the Ten Commandments) and the Lord's Prayer, which are also part of the Lutheran catechical teaching.

Luther had published his German translation of the New Testament in 1522, and he and his collaborators completed the translation of the Old Testament in 1534, when the whole Bible was published. He continued to work on refining the translation until the end of his life. Others had translated the Bible into German, but Luther tailored his translation to his own doctrine. When he was criticised for inserting the word "alone" after "faith" in Romans 3:28, he replied in part: "[T]he text itself and the meaning of St. Paul urgently require and demand it. For in that very passage he is dealing with the main point of Christian doctrine, namely, that we are justified by faith in Christ without any works of the Law. ... But when works are so completely cut away – and that must mean that faith alone justifies – whoever would speak plainly and clearly about this cutting away of works will have to say, 'Faith alone justifies us, and not works'."

Luther's translation used the variant of German spoken at the Saxon chancellery, intelligible to both northern and southern Germans. He intended his vigorous, direct language to make the Bible accessible to everyday Germans, "for we are removing impediments and difficulties so that other people may read it without hindrance."
