Lactantius: Justice had no other reason for leaving the earth than the shedding of human blood
From Divine Institutes
Translated by William Fletcher
“Then war’s indomitable rage,
And greedy lust of gain;” (Virgil, Aeneid )
and not without reason. For the worship of God being taken away, men lost the knowledge of good and evil. Thus the common intercourse of life perished from among then, and the bond of human society was destroyed. Then they began to contend with one another, and to plot, and to acquire for themselves glory from the shedding of human blood.
Be just and good, and the justice which you seek will follow you of her own accord. Lay aside every evil thought from your hearts, and that golden age will at once return to you…But if God only were worshipped, there would not be dissensions and wars, since men would know that they are the sons of one God; and, therefore, among those who were connected by the sacred and inviolable bond of divine relationship, there would be no plottings, inasmuch as they would know what kind of punishments God prepared for the destroyers of souls, who sees through secret crimes, and even the very thoughts themselves. There would be no frauds or plunderings if they had learned, through the instruction of God, to be content with that which was their own, though little, so that they might prefer solid and eternal things to those which are frail and perishable…How happy and how golden would be the condition of human affairs, if throughout the world gentleness, and piety, and peace, and innocence, and equity, and temperance, and faith, took up their abode! In short, there would be no need of so many and varying laws to rule men, since the law of God alone would be sufficient for perfect innocence; nor would there be any need of prisons, or the swords of rulers, or the terror of punishments, since the wholesomeness of the divine precepts infused into the breasts of men would of itself instruct them to works of justice.
[J]ustice, who had no other reason for leaving the earth than the shedding of human blood…Therefore they are to be accounted as savage beasts who injure man; who, in opposition to every law and right of human nature, plunder, torture, slay, and banish.
