A three volume set of source-books of theological and historical passages from the Christian writings of the Pre-Nicene and Nicene, Post Nicene, St. Augustine to the end of the patristic period. The passages selected are keyed to the numerical order established in M.J. Rouet de Journel's Enchiridion Patristicum. In no sense, however, are these volumes a translation of that standard work. The author has made his own investigation of theological textbooks in common use and has selected the patristic passages most frequently cited. Preceding each selection is a brief introduction treating the authorship, date and place of composition, and the purpose of the work from which the selection is taken. The author's scholarship and sense of humor are evident in these prefatoratory remarks. If immense value to the reader is the Doctrinal Index provided for each volume. Here one can find the text pertinent to particular doctrinal points, a method most useful to homilists. In addition, each volume is enhanced comprehensive Scriptural and General Indices.
