City of God, Book XXII
The expression of Scripture, “And all flesh shall see the salvation of God,” may without difficulty be understood as if it were said, “And every man shall see the Christ of God.” And He certainly was seen in the body, and shall be seen in the body when He judges quick and dead. And that Christ is the salvation of God, many other passages of Scripture witness, but especially the words of the venerable Simeon, who, when he had received into his hands the infant Christ, said, “Now lettest Thou Thy servant depart in peace, according to Thy word: for mine eyes have seen Thy salvation.” As for the words of the above-mentioned Job, as they are found in the Hebrew manuscripts, “And in my flesh I shall see God,” no doubt they were a prophecy of the resurrection of the flesh; yet he does not say “by the flesh.” And indeed, if he had said this, it would still be possible that Christ was meant by “God;” for Christ shall be seen by the flesh in the flesh. But even understanding it of God, it is only equivalent to saying, I shall be in the flesh when I see God. Then the apostle’s expression, “face to face,” does not oblige us to believe that we shall see God by the bodily face in which are the eyes of the body, for we shall see Him without intermission in spirit. And if the apostle had not referred to the face of the inner man, he would not have said, “But we, with unveiled face beholding as in a glass the glory of the Lord, are transformed into the same image, from glory to glory, as by the spirit of the Lord.” In the same sense we understand what the Psalmist sings, “Draw near unto Him, and be enlightened; and your faces shall not be ashamed.” For it is by faith we draw near to God, and faith is an act of the spirit, not of the body. But as we do not know what degree of perfection the spiritual body shall attain,—for here we speak of a matter of which we have no experience, and upon which the authority of Scripture does not definitely pronounce,—it is necessary that the words of the Book of Wisdom be illustrated in us: “The thoughts of mortal men are timid, and our fore-castings uncertain.”
For if that reasoning of the philosophers, by which they attempt to make out that intelligible or mental objects are so seen by the mind, and sensible or bodily objects so seen by the body, that the former cannot be discerned by the mind through the body, nor the latter by the mind itself without the body,—if this reasoning were trustworthy, then it would certainly follow that God could not be seen by the eye even of a spiritual body. But this reasoning is exploded both by true reason and by prophetic authority. For who is so little acquainted with the truth as to say that God has no cognisance of sensible objects? Has He therefore a body, the eyes of which give Him this knowledge? Moreover, what we have just been relating of the prophet Elisha, does this not sufficiently show that bodily things can be discerned by the spirit without the help of the body? For when that servant received the gifts, certainly this was a bodily or material transaction, yet the prophet saw it not by the body, but by the spirit. As, therefore, it is agreed that bodies are seen by the spirit, what if the power of the spiritual body shall be so great that spirit also is seen by the body? For God is a spirit. Besides, each man recognizes his own life—that life by which he now lives in the body, and which vivifies these earthly members and causes them to grow—by an interior sense, and not by his bodily eye; but the life of other men, though it is invisible, he sees with the bodily eye. For how do we distinguish between living and dead bodies, except by seeing at once both the body and the life which we cannot see save by the eye? But a life without a body we cannot see thus.
Wherefore it may very well be, and it is thoroughly credible, that we shall in the future world see the material forms of the new heavens and the new earth in such a way that we shall most distinctly recognize God everywhere present and governing all things, material as well as spiritual, and shall see Him, not as now we understand the invisible things of God, by the things which are made, and see Him darkly, as in a mirror, and in part, and rather by faith than by bodily vision of material appearances, but by means of the bodies we shall wear and which we shall see wherever we turn our eyes. As we do not believe, but see that the living men around us who are exercising vital functions are alive, though we cannot see their life without their bodies, but see it most distinctly by means of their bodies, so, wherever we shall look with those spiritual eyes of our future bodies, we shall then, too, by means of bodily substances behold God, though a spirit, ruling all things. Either, therefore, the eyes shall possess some quality similar to that of the mind, by which they may be able to discern spiritual things, and among these God,—a supposition for which it is difficult or even impossible to find any support in Scripture,—or, which is more easy to comprehend, God will be so known by us, and shall be so much before us, that we shall see Him by the spirit in ourselves, in one another, in Himself, in the new heavens and the new earth, in every created thing which shall then exist; and also by the body we shall see Him in every body which the keen vision of the eye of the spiritual body shall reach. Our thoughts also shall be visible to all, for then shall be fulfilled the words of the apostle, “Judge nothing before the time, until the Lord come, who both will bring to light the hidden things of darkness, and will make manifest the thoughts of the heart, and then shall every one have praise of God.”
Chapter 30.—Of the Eternal Felicity of the City of God, and of the Perpetual Sabbath.
How great shall be that felicity, which shall be tainted with no evil, which shall lack no good, and which shall afford leisure for the praises of God, who shall be all in all! For I know not what other employment there can be where no lassitude shall slacken activity, nor any want stimulate to labor. I am admonished also by the sacred song, in which I read or hear the words, “Blessed are they that dwell in Thy house, O Lord; they will be still praising Thee.” All the members and organs of the incorruptible body, which now we see to be suited to various necessary uses, shall contribute to the praises of God; for in that life necessity shall have no place, but full, certain, secure, everlasting felicity. For all those parts of the bodily harmony, which are distributed through the whole body, within and without, and of which I have just been saying that they at present elude our observation, shall then be discerned; and, along with the other great and marvellous discoveries which shall then kindle rational minds in praise of the great Artificer, there shall be the enjoyment of a beauty which appeals to the reason. What power of movement such bodies shall possess, I have not the audacity rashly to define, as I have not the ability to conceive. Nevertheless I will say that in any case, both in motion and at rest, they shall be, as in their appearance, seemly; for into that state nothing which is unseemly shall be admitted. One thing is certain, the body shall forthwith be wherever the spirit wills, and the spirit shall will nothing which is unbecoming either to the spirit or to the body. True honor shall be there, for it shall be denied to none who is worthy, nor yielded to any unworthy; neither shall any unworthy person so much as sue for it, for none but the worthy shall be there. True peace shall be there, where no one shall suffer opposition either from himself or any other. God Himself, who is the Author of virtue, shall there be its reward; for, as there is nothing greater or better, He has promised Himself. What else was meant by His word through the prophet, “I will be your God, and ye shall be my people,” than, I shall be their satisfaction, I shall be all that men honorably desire,—life, and health, and nourishment, and plenty, and glory, and honor, and peace, and all good things? This, too, is the right interpretation of the saying of the apostle, “That God may be all in all.” He shall be the end of our desires who shall be seen without end, loved without cloy, praised without weariness. This outgoing of affection, this employment, shall certainly be, like eternal life itself, common to all.
