Homily VI.
The creation of luminous bodies.
1. At the shows in the circus the spectator must join in the efforts of the athletes. This the laws of the show indicate, for they prescribe that all should have the head uncovered when present at the stadium. The object of this, in my opinion, is that each one there should not only be a spectator of the athletes, but be, in a certain measure, a true athlete himself. [1565] Thus, to investigate the great and prodigious show of creation, to understand supreme and ineffable wisdom, you must bring personal light for the contemplation of the wonders which I spread before your eyes, and help me, according to your power, in this struggle, where you are not so much judges as fellow combatants, [1566] for fear lest the truth might escape you, and lest my error might turn to your common prejudice. Why these words? It is because we propose to study the world as a whole, and to consider the universe, not by the light of worldly wisdom, but by that with which God wills to enlighten His servant, when He speaks to him in person and without enigmas. It is because it is absolutely necessary that all lovers of great and grand shows should bring a mind well prepared to study them. If sometimes, on a bright night, [1567] whilst gazing with watchful eyes on the inexpressible beauty of the stars, you have thought of the Creator of all things; if you have asked yourself who it is that has dotted heaven with such flowers, and why visible things are even more useful than beautiful; if sometimes, in the day, you have studied the marvels of light, if you have raised yourself by visible things to the invisible Being, then you are a well prepared auditor, and you can take your place in this august and blessed amphitheatre. Come in the same way that any one not knowing a town is taken by the hand and led through it; thus I am going to lead you, like strangers, through the mysterious marvels of this great city of the universe. [1568] Our first country was in this great city, whence the murderous dæmon whose enticements seduced man to slavery expelled us. There you will see man's first origin and his immediate seizure by death, brought forth by sin, the first born of the evil spirit. You will know that you are formed of earth, but the work of God's hands; much weaker than the brute, but ordained to command beings without reason and soul; inferior as regards natural advantages, but, thanks to the privilege of reason, capable of raising yourself to heaven. If we are penetrated by these truths, we shall know ourselves, we shall know God, we shall adore our Creator, we shall serve our Master, we shall glorify our Father, we shall love our Sustainer, we shall bless our Benefactor, we shall not cease to honour the Prince [1569] of present and future life, Who, by the riches that He showers upon us in this world, makes us believe in His promises and uses present good things to strengthen our expectation of the future. Truly, if such are the good things of time, what will be those of eternity? If such is the beauty of visible things, what shall we think of invisible things? If the grandeur of heaven exceeds the measure of human intelligence, what mind shall be able to trace the nature of the everlasting? If the sun, subject to corruption, is so beautiful, so grand, so rapid in its movement, so invariable in its course; if its grandeur is in such perfect harmony with and due proportion to the universe: if, by the beauty of its nature, it shines like a brilliant eye in the middle of creation; if finally, one cannot tire of contemplating it, what will be the beauty of the Sun of Righteousness? [1570] If the blind man suffers from not seeing the material sun, what a deprivation is it for the sinner not to enjoy the true light!
2. "And God said, Let there be lights in the firmament of the heaven to give light upon the earth, and to divide the day from the night." [1571] Heaven and earth were the first; after them was created light; the day had been distinguished from the night, then had appeared the firmament and the dry element. The water had been gathered into the reservoir assigned to it, the earth displayed its productions, it had caused many kinds of herbs to germinate and it was adorned with all kinds of plants. However, the sun and the moon did not yet exist, in order that those who live in ignorance of God may not consider the sun as the origin and the father of light, or as the maker of all that grows out of the earth. [1572] That is why there was a fourth day, and then God said: "Let there be lights in the firmament of the heaven."
When once you have learnt Who spoke, think immediately of the hearer. God said, "Let there be lights...and God made two great lights." Who spoke? and Who made? Do you not see a double person? Everywhere, in mystic language, history is sown with the dogmas of theology.
The motive follows which caused the lights to be created. It was to illuminate the earth. Already light was created; why therefore say that the sun was created to give light? And, first, do not laugh at the strangeness of this expression. We do not follow your nicety about words, and we trouble ourselves but little to give them a harmonious turn. Our writers do not amuse themselves by polishing their periods, and everywhere we prefer clearness of words to sonorous expressions. See then if by this expression "to light up," the sacred writer sufficiently made his thought understood. He has put "to give light" [1573] instead of "illumination." [1574] Now there is nothing here contradictory to what has been said of light. Then the actual nature of light was produced: now the sun's body is constructed to be a vehicle for that original light. A lamp is not fire. Fire has the property of illuminating, and we have invented the lamp to light us in darkness. In the same way, the luminous bodies have been fashioned as a vehicle for that pure, clear, and immaterial light. The Apostle speaks to us of certain lights which shine in the world [1575] without being confounded with the true light of the world, the possession of which made the saints luminaries of the souls which they instructed and drew from the darkness of ignorance. This is why the Creator of all things, made the sun in addition to that glorious light, and placed it shining in the heavens.
3. And let no one suppose it to be a thing incredible that the brightness of the light is one thing, and the body which is its material vehicle is another. First, in all composite things, we distinguish substance susceptible of quality, and the quality which it receives. The nature of whiteness is one thing, another is that of the body which is whitened; thus the natures differ which we have just seen reunited by the power of the Creator. And do not tell me that it is impossible to separate them. Even I do not pretend to be able to separate light from the body of the sun; but I maintain that that which we separate in thought, may be separated in reality by the Creator of nature. You cannot, moreover, separate the brightness of fire from the virtue of burning which it possesses; but God, who wished to attract His servant by a wonderful sight, set a fire in the burning bush, which displayed all the brilliancy of flame while its devouring property was dormant. It is that which the Psalmist affirms in saying "The voice of the Lord divideth the flames of fire." [1576] Thus, in the requital which awaits us after this life, a mysterious voice seems to tell us that the double nature of fire will be divided; the just will enjoy its light, and the torment of its heat will be the torture of the wicked.
In the revolutions of the moon we find anew proof of what we have advanced. When it stops and grows less it does not consume itself in all its body, but in the measure that it deposits or absorbs the light which surrounds it, it presents to us the image of its decrease or of its increase. If we wish an evident proof that the moon does not consume its body when at rest, we have only to open our eyes. If you look at it in a cloudless and clear sky, you observe, when it has taken the complete form of a crescent, that the part, which is dark and not lighted up, describes a circle equal to that which the full moon forms. Thus the eye can take in the whole circle, if it adds to the illuminated part this obscure and dark curve. And do not tell me that the light of the moon is borrowed, diminishing or increasing in proportion as it approaches or recedes from the sun. That is not now the object of our research; we only wish to prove that its body differs from the light which makes it shine. I wish you to have the same idea of the sun; except however that the one, after having once received light and having mixed it with its substance, does not lay it down again, whilst the other, turn by turn, putting off and reclothing itself again with light, proves by that which takes place in itself what we have said of the sun.
The sun and moon thus received the command to divide the day from the night. God had already separated light from darkness; then He placed their natures in opposition, so that they could not mingle, and that there could never be anything in common between darkness and light. You see what a shadow is during the day; that is precisely the nature of darkness during the night. If, at the appearance of a light, the shadow always falls on the opposite side; if in the morning it extends towards the setting sun; if in the evening it inclines towards the rising sun, and at mid-day turns towards the north; night retires into the regions opposed to the rays of the sun, since it is by nature only the shadow of the earth. Because, in the same way that, during the day, shadow is produced by a body which intercepts the light, night comes naturally when the air which surrounds the earth is in shadow. And this is precisely what Scripture says, "God divided the light from the darkness." Thus darkness fled at the approach of light, the two being at their first creation divided by a natural antipathy. Now God commanded the sun to measure the day, and the moon, whenever she rounds her disc, to rule the night. For then these two luminaries are almost diametrically opposed; when the sun rises, the full moon disappears from the horizon, to re-appear in the east at the moment the sun sets. It matters little to our subject if in other phases the light of the moon does not correspond exactly with night. It is none the less true, that when at its perfection it makes the stars to turn pale and lightens up the earth with the splendour of its light, it reigns over the night, and in concert with the sun divides the duration of it in equal parts.
4. "And let them be for signs, and for seasons, and for days and years." [1577] The signs which the luminaries give are necessary to human life. In fact what useful observations will long experience make us discover, if we ask without undue curiosity! What signs of rain, of drought, or of the rising of the wind, partial or general, violent or moderate! Our Lord indicates to us one of the signs given by the sun when He says, "It will be foul weather to-day; for the sky is red and lowering." [1578] In fact, when the sun rises through a fog, its rays are darkened, but the disc appears burning like a coal and of a bloody red colour. It is the thickness of the air which causes this appearance; as the rays of the sun do not disperse such amassed and condensed air, it cannot certainly be retained by the waves of vapour which exhale from the earth, and it will cause from superabundance of moisture a storm in the countries over which it accumulates. In the same way, when the moon is surrounded with moisture, or when the sun is encircled with what is called a halo, it is the sign of heavy rain or of a violent storm; again, in the same way, if mock suns accompany the sun in its course they foretell certain celestial phenomena. Finally, those straight lines, like the colours of the rainbow, which are seen on the clouds, announce rain, extraordinary tempests, or, in one word, a complete change in the weather.
