The creation of fowl and water animals.
7. “ Let the waters bring forth the moving creatures that have life, and fowl that may fly above the earth in the open firmament of heaven.” They received the command to fly above the earth because earth provides them with nourishment. “In the firmament of heaven,” that is to say, as we have said before, in that part of the air called οὐρανός , heaven, from the word ὁρᾶν , which means to see; called firmament, because the air which extends over our heads, compared to the æther, has greater density, and is thickened by the vapours which exhale from the earth. You have then heaven adorned, earth beautified, the sea peopled with its own creatures, the air filled with birds which scour it in every direction. Studious listener, think of all these creations which God has drawn out of nothing, think of all those which my speech has left out, to avoid tediousness, and not to exceed my limits; recognise everywhere the wisdom of God; never cease to wonder, and, through every creature, to glorify the Creator.
There are some kinds of birds which live by night in the midst of darkness; others which fly by day in full light. Bats, owls, night-ravens are birds of night: if by chance you cannot sleep, reflect on these nocturnal birds and their peculiarities and glorify their Maker. How is it that the nightingale is always awake when sitting on her eggs, passing the night in a continual melody? How is it that one animal, the bat, is at the same time quadruped and fowl? That it is the only one of the birds to have teeth? That it is viviparous like quadrupeds, and traverses the air, raising itself not upon wings, but upon a kind of membrane? What natural love bats have for each other! How they interlace like a chain and hang the one upon the other! A very rare spectacle among men, who for the greater part prefer individual and private life to the union of common life. Have not those who give themselves up to vain science the eyes of owls? The sight of the owl, piercing during the night time, is dazzled by the splendour of the sun; thus the intelligence of these men, so keen to contemplate vanities, is blind in presence of the true light.
During the day, also, how easy it is for you to admire the Creator everywhere! See how the domestic cock calls you to work with his shrill cry, and how, forerunner of the sun, and early as the traveller, he sends forth labourers to the harvest! What vigilance in geese! With what sagacity they divine secret dangers! Did they not once upon a time save the imperial city? When enemies were advancing by subterranean passages to possess themselves of the capitol of Rome, did not geese announce the danger? Is there any kind of bird whose nature offers nothing for our admiration? Who announces to the vultures that there will be carnage when men march in battle array against one another? You may see flocks of vultures following armies and calculating the result of warlike preparations; a calculation very nearly approaching to human reasoning. How can I describe to you the fearful invasions of locusts, which rise everywhere at a given signal, and pitch their camps all over a country? They do not attack crops until they have received the divine command. Or shall I describe how the remedy for this curse, the thrush, follows them with its insatiable appetite, and the devouring nature that the loving God has given it in His kindness for men? How does the grasshopper modulate its song? Why is it more melodious at midday owing to the air that it breathes in dilating its chest?
But it appears to me that in wishing to describe the marvels of winged creatures, I remain further behind than I should if my feet had tried to match the rapidity of their flight. When you see bees, wasps, in short all those flying creatures called insects, because they have an incision all around, reflect that they have neither respiration nor lungs, and that they are supported by air through all parts of their bodies. Thus they perish, if they are covered with oil, because it stops up their pores. Wash them with vinegar, the pores reopen and the animal returns to life. Our God has created nothing unnecessarily and has omitted nothing that is necessary. If now you cast your eyes upon aquatic creatures, you will find that their organization is quite different. Their feet are not split like those of the crow, nor hooked like those of the carnivora, but large and membraneous; therefore they can easily swim, pushing the water with the membranes of their feet as with oars. Notice how the swan plunges his neck into the depths of the water to draw his food from it, and you will understand the wisdom of the Creator in giving this creature a neck longer than his feet, so that he may throw it like a line, and take the food hidden at the bottom of the water.
8. If we simply read the words of Scripture we find only a few short syllables. “Let the waters bring forth fowl that may fly above the earth in the open firmament of heaven,” but if we enquire into the meaning of these words, then the great wonder of the wisdom of the Creator appears. What a difference He has foreseen among winged creatures! How He has divided them by kinds! How He has characterized each one of them by distinct qualities! But the day will not suffice me to recount the wonders of the air. Earth is calling me to describe wild beasts, reptiles and cattle, ready to show us in her turn sights rivalling those of plants, fish, and birds. “Let the earth bring forth the living soul” of domestic animals, of wild beasts, and of reptiles after their kind. What have you to say, you who do not believe in the change that Paul promises you in the resurrection, when you see so many metamorphoses among creatures of the air? What are we not told of the horned worm of India! First it changes into a caterpillar, then becomes a buzzing insect, and not content with this form, it clothes itself, instead of wings, with loose, broad plates. Thus, O women, when you are seated busy with your weaving, I mean of the silk which is sent you by the Chinese to make your delicate dresses, remember the metamorphoses of this creature, conceive a clear idea of the resurrection, and do not refuse to believe in the change that Paul announces for all men.
But I am ashamed to see that my discourse oversteps the accustomed limits; if I consider the abundance of matters on which I have just discoursed to you, I feel that I am being borne beyond bounds; but when I reflect upon the inexhaustible wisdom which is displayed in the works of creation, I seem to be but at the beginning of my story. Nevertheless, I have not detained you so long without profit. For what would you have done until the evening? You are not pressed by guests, nor expected at banquets. Let me then employ this bodily fast to rejoice your souls. You have often served the flesh for pleasure, to-day persevere in the ministry of the soul. “Delight thyself also in the Lord and he shall give thee the desire of thine heart.” Do you love riches? Here are spiritual riches. “The judgments of the Lord are true and righteous altogether. More to be desired are they than gold and precious stones.” Do you love enjoyment and pleasures? Behold the oracles of the Lord, which, for a healthy soul, are “sweeter than honey and the honey-comb.”
If I let you go, and if I dismiss this assembly, some will run to the dice, where they will find bad language, sad quarrels and the pangs of avarice. There stands the devil, inflaming the fury of the players with the dotted bones, transporting the same sums of money from one side of the table to the other, now exalting one with victory and throwing the other into despair, now swelling the first with boasting and covering his rival with confusion. Of what use is bodily fasting and filling the soul with innumerable evils? He who does not play spends his leisure elsewhere. What frivolities come from his mouth! What follies strike his ears! Leisure without the fear of the Lord is, for those who do not know the value of time, a school of vice. I hope that my words will be profitable; at least by occupying you here they have prevented you from sinning. Thus the longer I keep you, the longer you are out of the way of evil.
An equitable judge will deem that I have said enough, not if he considers the riches of creation, but if he thinks of our weakness and of the measure one ought to keep in that which tends to pleasure. Earth has welcomed you with its own plants, water with its fish, air with its birds; the continent in its turn is ready to offer you as rich treasures. But let us put an end to this morning banquet, for fear satiety may blunt your taste for the evening one. May He who has filled all with the works of His creation and has left everywhere visible memorials of His wonders, fill your hearts with all spiritual joys in Jesus Christ, our Lord, to whom belong glory and power, world without end. Amen.
