The collection contained in the volumes before us is, however, more varied and comprehensive, reaching as it does from the fourth to the twentieth century, than any collection known to the writer. In the selection Professor Kleiser has brought to his task a personal knowledge of homiletic literature that is the product of much observation and study during many years, and an enthusiasm for his work that has been fostered by close intercourse in professional service with preachers and theological students. He has had the assistance also of men whose acquaintance with homiletic literature is very extensive, whose critical judgments are sound and reliable and who may be regarded as experts in this branch of knowledge. These volumes, therefore, may be accepted as a judiciously selected collection of sermons by many of the most notable preachers of the ancient and modern Christian world. Their value as illustrating varieties of gift, diversities of method, racial, national and ecclesiastical peculiarities, and above all progress in the science and art of preaching, may well be recognized even by a generation that is likely to regard anything that is more than twenty-four hours old as obsolete.
