We have spoken of Luther's Small Catechism as a help with which to lay hold of and understand the most important truths of the Bible. These fundamental truths are taken from the Scriptures, and are so grouped, arranged and explained that the learner can easily grasp and understand them. That some of the truths contained in the Bible are of greater importance than others will scarcely be denied. It is certainly more important that the child should know and understand the Ten Commandments, than that it should be familiar with all the details of the ceremonial law. Certainly better to be familiar with the Apostles' Creed, than to know all about the building of the Temple. Better be able to repeat and understand the Lord's Prayer, than to have a clear knowledge of the elaborate ritual of the Temple service. Better understand the meaning of Christ's two Sacraments than to be able to tell all about the great feasts of the Jews. If any one can know all these other matters also, so much the better. The Catechism will certainly be a help instead of a hindrance to this end. But if all cannot be learned--at least not at once--let the most important be taught first. And for this we have a Catechism. Look at its contents. It is divided into five parts. Each division treats of a separate subject. The first contains the Ten Commandments, with a brief yet full explanation of each Commandment. The second part has the three articles of the Apostles' Creed, with a clear and most beautiful explanation of each one. The third is the Lord's Prayer, its introduction, the seven petitions, and the conclusion; with a terse, though comprehensive explanation of each sentence. The fourth and fifth parts treat similarly of the two sacraments, Baptism and the Lord's Supper. Here then we have, in a brief space, the most important teachings of the whole Bible systematically arranged and clearly explained. Of these contents and their arrangement, Luther himself says: "This Catechism is truly the Bible of the laity (or common people), wherein is contained the entire doctrine necessary to be known by every Christian for salvation. Here we have first the Ten Commandments of God, the doctrine of doctrines, by which the will of God is known, what God would have us to do and what is wanting in us. "Secondly: The Apostles' Creed, the history of histories, or the highest history, wherein are delivered to us the wonderful works of God from the beginning, how we and all creatures are created by God, how all are redeemed by the Son of God, how we are also received and sanctified by the Holy Ghost, and collected together to a people of God, and have the remission of sins and everlasting salvation. "Thirdly: The Lord's Prayer, the prayer of prayers, the highest prayer which the highest Master taught, wherein are included all temporal and spiritual blessings, and the strongest comforts in all temptations and troubles, and in the hour of death.
