City of God: Chapter 11

Chapter 11.—Of the Happiness of the Eternal Peace, Which Constitutes the End or True Perfection of the Saints.

And thus we may say of peace, as we have said of eternal life, that it is the end of our good; and the rather because the Psalmist says of the city of God, the subject of this laborious work, “Praise the Lord, O Jerusalem; praise thy God, O Zion:  for He hath strengthened the bars of thy gates; He hath blessed thy children within thee; who hath made thy borders peace.” 1278   For when the bars of her gates shall be strengthened, none shall go in or come out from her; consequently we ought to understand the peace of her borders as that final peace we are wishing to declare.  For even the mystical name of the city itself, that is, Jerusalem, means, as I have already said, “Vision of Peace.”  But as the word peace is employed in connection with things in this world in which certainly life eternal has no place, we have preferred to call the end or supreme good of this city life eternal rather than peace.  Of this end the apostle says, “But now, being freed from sin, and become servants to God, ye have your fruit unto holiness, and the end life eternal.” 1279   But, on the other hand, as those who are not familiar with Scripture may suppose that the life of the wicked is eternal life, either because of the immortality of the soul, which some of the philosophers even have recognized, or because of the endless punishment of the wicked, which forms a part of our faith, and which seems impossible unless the wicked live for ever, it may therefore be advisable, in order that every one may readily understand what we mean, to say that the end or supreme good of this city is either peace in eternal life, or eternal life in peace.  For peace is a good so great, that even in this earthly and mortal life there is no word we hear with such pleasure, nothing we desire with such zest, or find to be more thoroughly gratifying.  So that if we dwell for a little longer on this subject, we shall not, in my opinion, be wearisome to our readers, who will attend both for the sake of understanding what is the end of this city of which we speak, and for the sake of the sweetness of peace which is dear to all.
