The Pædagogus, or Instructor, is addressed to those who have been rescued from the darkness and pollutions of heathenism and is an exhibition of Christian morals and manners, a guide for the formation and development of Christian character and for living a Christian life. It consists of three books. It is the grand aim of the whole work to set before the converts Christ as the only instructor, and to expound and enforce his precepts.

In the first book, Clement of Alexandria exhibits the person, the function, the means, methods, and ends of the Instructor, who is the word and son of God; and lovingly dwells on his benignity and philanthropy, his wisdom, faithfulness, and righteousness. The second and third books lay down rules for the regulation of the Christian, in all the relations, circumstances, and actions of life, entering most minutely into the details of dress, eating, drinking, bathing, sleeping, etc.

The delineation of a life in all respects agreeable to the word, a truly Christian life, attempted here, may, now that the Gospel has transformed social and private life to the extent it has, appear unnecessary, or a proof of the influence of ascetic tendencies. But a code of Christian morals and manners (a sort of manual of good breeding) was eminently needed by those whose habits and characters had been molded under the debasing and polluting influences of heathenism; and who were bound, and were aiming, to shape their lives according to the principles of the Gospel, in the midst of the all but incredible licentiousness and luxury by which society around was incurably tainted. The disclosures which Clement, with solemn sternness, and often with caustic wit, makes of the prevalent voluptuousness and vice, form a very valuable contribution to our knowledge of that period.
