Collections of sermons by noted preachers of different periods are not an altogether uncommon contribution to literature. Italy, Germany, Holland, France, Great Britain and the United States have in this way furnished copious illustrations of the gifts of their illustrious preachers. Such treasures are found in the Latin and even in the Greek Church. Protestant communions especially, in line with the supreme significance which they attach to the work of the pulpit, have thus sought to magnify the calling and to perpetuate the memory and the influence of their distinguished sons. Still more comprehensive attempts have been made to collate the products of representative preachers in different Protestant communions, and thus to bring into prominence various types of sermonic literature. It is in this way that the Christian world has come to know its pulpit princes and to value their achievements.
