It is composed of ten documents, each of which has been recognized as authoritative in Lutheranism since at least the 16th century. (The Three Ecumenical Creeds, The Augsburg Confession, The Apology of the Augsburg Confession, The Smalcald Articles, A Treatise of the Power and Primacy of the Pope, Luther's Small and large Catechisms, and The Formula of Concord.) They are also known as the symbolical books of the Evangelical Lutheran Church, or the Lutheran Confessions.

The purpose of this book is to present the records of the life of Jesus in that form which will make most fully available the contributions of the several sources, both individual and collective, to an understanding of the actual career of Jesus. It has been the aim so as to set forth the material as to provide primarily for an historical rather than a critical knowledge of the records. Stated in another way, the foremost intention has been to produce, in the language and in the order of the original records, a Life of Jesus. But it is thought also that, in the pursuance of that aim, the literary phenomena of the records have been so exhibited as to provide the basis for somewhat thorough critical study of the source relationships of these records.

    In "Magic Squares and Cubes" W.S. Andrews writes "The study of magic squares probably dates back to prehistoric times. Examples have been found in Chinese literature written about AD 1125 which were evidently copied from still older documents. It is recorded that as early as the ninth century magic squares were used by Arabian astrologers in their calculations of horoscopes, etc. Hence, the probable origin of the term magic, which has survived to the present day." Topics such as magic squares, magic cubes, the Franklin squares, magics and Pythagorean numbers, the theory of reversions, magic circles, spheres, and stars, and magic octahedroids, among other things.
