XXXIV. Moreover, to Ignorant Gentiles.
The unsubdued neck refuses to bear the yoke of labour. Then it delights to be satisfied with herbs in the rich plains. And still unwillingly is subdued the useful mare, and it is made to be less fierce when it is first brought into subjection. O people, O man, you brother, do not be a brutal flock. Pluck yourself forth at length, and yourself withdraw yourself. Assuredly you are not cattle, you are not a beast, but you are born a man. Do you yourself wisely subdue yourself, and enter under arms.
You who follow idols are nothing but the vanity of the age. Your trifling hearts destroy you when almost set free. There gold, garments, silver is brought to the elbows; there war is made; there love is sung of instead of psalms. Do you think it to be life, when you play or lookest forward to such things as these? You choose, O ignorant one, things that are extinct; you seek golden things. Thence you shall not escape the plague, although yourself art divine. You seek not that grace which God sent to be read of in the earth, but thus as a beast you wander. The golden age before spoken of shall come to you if you believe, and again you shall begin to live always an immortal life. That also is permitted to know what you were before. Give yourself as a subject to God, who governs all things.
