This edition presents in English language, and in convenient-size soft cover volumes, a selection of the most indispensable Christian treatises written before the end of the sixteenth century. These books meet the need of lay people and libraries, students and pastors, for a single set of books containing the great literature of the Christian heritage. The texts are heightened in usefulness by a wealth of introductory material, explanatory notes, bibliographies, and indexes. The contents of each volume are exactly the same as in the original hardbound edition.
