Theophilus to Autolycus

And on the sixth day, God having made the quadrupeds, and wild beasts, and the land reptiles, pronounced no blessing upon them, reserving His blessing for man, whom He was about to create on the sixth day. The quadrupeds, too, and wild beasts, were made for a type of some men, who neither know nor worship God, but mind earthly things, and repent not. For those who turn from their iniquities and live righteously, in spirit fly upwards like birds, and mind the things that are above, and are well-pleasing to the will of God.

But those who do not know nor worship God, are like birds which have wings, but cannot fly nor soar to the high things of God. Thus, too, though such persons are called men, yet being pressed down with sins, they mind grovelling and earthly things. And the animals are named wild beasts [θηρία], from their being hunted [θηρεύεσθαι], not as if they had been made evil or venomous from the first— for nothing was made evil by God, but all things good, yea, very good—but the sin in which man was concerned brought evil upon them.

For when man transgressed, they also transgressed with him. For as, if the master of the house himself acts rightly, the domestics also of necessity conduct themselves well; but if the master sins, the servants also sin with him; so in like manner it came to pass, that in the case of man's sin, he being master, all that was subject to him sinned with him. When, therefore, man again shall have made his way back to his natural condition, and no longer does evil, those also shall be restored to their original gentleness.
