Author: Teigen, B. W. This publication has been well received and used in many Bible classes in the congregations. In view of this, Teigen recognized that in practical work Christian doctrine is taught in ever-widening concentric circles, has provided in the last two studies more material of a historical and theological nature. Since the study of the Augsburg Confession was the final one in the series and since it is the most widely known and used of the specifically Lutheran confessions, the author has provided eighty pages of material for consideration by the general reader and the Bible study classes.
