Thomas Aquinas [Aquinas - Catechism of the Summa Theologica

Of

Translated by

Beloved Son,

Greeting and Apostolic Benediction.

The manifold honours paid by the Holy See to St. Thomas Aquinas exclude for ever any doubt from the mind of Catholics with regard to his being raised up by God as the Master of Doctrine to be followed by the Church through all ages. It was therefore fitting that the singular wisdom of the Holy Doctor should be made accessible not only to the clergy but to the faithful in general, and to whomsoever desired to make a deeper study of the things of religion; for in very truth, the nearer one approaches to the light, so much the more is one enlightened.

Much praise is therefore due to you first of all because you have undertaken to write a commentary in your mother tongue upon the greatest work of the Angelic Doctor, viz., the Summa Theologica (the volumes already published of this work show what success has attended your labours); and, secondly, because you have recently published the Summa Theologica in the form of a catechism. Therein you have aptly accommodated the riches of the great genius to the understanding of the less instructed as well as of the learned; briefly and succinctly you have expounded the doctrine, and in the same luminous order as that of the Angelic Doctor whose treatise is more lengthy and more detailed.

We congratulate you sincerely on this fruit of your labours which shows your masterly knowledge of St. Thomas' doctrine. We hope, therefore, through your love of Holy Church that this work will bring many souls to a sound knowledge of Christian doctrine.

As a mark of the divine largess and in testimony of our own special good will we impart in all affection to you and to your pupils the Apostolic Benediction.

POPE BENEDICT XV.

The author of the original work asked me personally to translate his book into English. I have done so; but the genius of the English language did not permit a literal translation. The present book is therefore in some sense rather an adaptation than a literal translation, although the latter has been strictly adhered to wherever possible.

In the original work the answer always repeats the whole question word for word; in the cause of brevity and sometimes for clearness' sake, I have adopted the simple answer of "yes" or "no" lest the reader tire with the insistency of the ceaseless repetition.

Those readers who wish to study the doctrine more deeply will find much help in the references quoted at the end of most of the answers to the questions; they refer to the Summa Theologica itself, which has been translated literally into English by the Dominican Fathers of the English Province. To take an example: On p. 9 of this book there is the question: Does the Providence of God extend also to inanimate things? And the answer: Yes, for they are a part of God's handiwork (XXII. 2, Obj, 5). The reference here quoted means that the doctrine in its every detail is to be found in the reply to the 5th Objection of the 2nd Article of the 22nd Question of the First Part of the Summa. It should be noted that the citation of "First Part" is not added to the quotation for the simple reason that the particular "part" of the Summa to which the quotation refers may easily be found by consulting the table of Contents. Moreover, whenever necessary and in order to give additional strength to the doctrines of St. Thomas, reference has been made to the new Code of Canon Law; e.g., on p. 289 (Code, Canon 1036). Thus this work is brought up to date.
