This Catechism is divided into three parts: The first part treats of faith, the second of morals, the third of the means of grace. In the first part Our Lord appears in His character of Teacher; in the second in His character of King; and in the third in His character of High Priest. And since this Catechism proposes as its primary object to answer the question, for what purpose are we here upon earth, thereby emphasizing and giving prominence to man's high calling and destiny, it is especially suited to the present day, when the pursuit of material interests, self-indulgence and pleasure, engrosses the attention of so many. This Catechism is in fact nothing more nor less than an abstract of Our Lord's teaching, and may be called a guide book for the Christian on the road to heaven. - Preface.
