With this object in view, I have not attempted, in the present work, to give an exhaustive commentary on the Fourth Gospel. Such an attempt, indeed, would have frustrated my object. I have tried rather, while omitting nothing of importance, to introduce nothing unnecessary, and to observe throughout the utmost consistent brevity. I am prepared to hear that some will consider I have passed too lightly over the easier portions of the Gospel. I can only say, in reply, that what I have done, has been done deliberately. Where the meaning of God’s word is sufficiently clear, I consider that it ought to be left to the exercise of the student’s intelligence to find it, and I am strongly of opinion that in such cases a commentator may well be excused from interposing his remarks between the reader and the Sacred Text. It might seem that the able and learned commentary of Dr. MacEvilly—the only Catholic commentary hitherto existing on this Gospel in the English language—would render such a work as the present unnecessary. But the length of His Grace’s work, like the works of Maldonatus, Estius, and A Lapide, renders it not wholly adapted to the present conditions of our students. Besides, anyone acquainted with the work of a professor will readily realize how important it is, and how desirable, when possible, that students should possess in handy and permanent form the professor’s views. No two men will think alike on all the difficult and intricate questions arising out of the Gospel of St. John; and while I should feel it my duty, if lecturing on the work of another, to impose upon the students of my class the necessity of taking notes, I have hope that the present work will to a large extent obviate such a necessity. His Grace’s work will, no doubt, continue to be used by many of our students in preference to mine, and with all of them it will still hold its place as a useful book of reference. The Latin Text that I have followed is a reprint from the Latin Vulgate published at Turin in 1883: _Biblia Sacra Vulgatae Editionis, Sixti V. Pontificis Maximi jussu recognita, et Clementis VIII. auctoritate edita. Editio emendatissima, Indicis Congregationis decreto probata, et iterum hoc anno evulgata. Augustae Taurinorum, typis Hyacinthi Marietti_, MDCCCLXXXIII. In only one instance is there a conscious departure from this edition, and that is in verses 3 and 4 of the first chapter, where I have returned to the original punctuation of the Clementine Edition. The English Text is from the Rhemish New Testament approved by Cardinal Wiseman, and published by Burns and Oates, Limited. MAYNOOTH COLLEGE, _Ascension Thursday, 1897_. INTRODUCTION.
