As the subtitle indicates, this book is not intended to be anything more than a brief introduction to the four gospels. It treats questions of sources, date and authorship, and the mutual relations of one Gospel to another. It does not attempt to discuss the deepest and most beautiful things in the Gospels, but rather those questions about which we must form opinions if we are to read these unique works with insight and understanding. This edition has been carefully revised, and notes and references have been added relating to the Q, the Proto-Luke, and Bussmann's Hypotheses, the authorship of 1 John, and the critical problems connected with the Fourth Gospel; and it should be of service to students and to the growing number of readers who are keenly interested in the question of Gospel Origins.
