Because that, when they knew God, they have not glorified him as God, or given thanks; but became vain in their thoughts, and their foolish heart was darkened.
Lucius Caecilius Firmianus Lactantius
When I reflect, O Emperor Constantine, and often revolve in my mind the original condition of men, it is accustomed to appear alike wonderful and unworthy that, by the folly of one age embracing various superstitions, and believing in the existence of many gods, they suddenly arrived at such ignorance of themselves, that the truth being taken away from their eyes, the religion of the true God was not observed, nor the condition of human nature, since men did not seek the chief good in heaven, but on earth. And on this account assuredly the happiness of the ancient ages was changed. For, having left God, the parent and founder of all things, men began to worship the senseless works of their own hands. And what were the effects of this corruption, or what evils it introduced, the subject itself sufficiently declares. For, turning away from the chief good, which is blessed and everlasting on this account, because it cannot be seen, or touched, or comprehended, and from the virtues which are in agreement with that good, and which are equally immortal, gliding down to these corrupt and frail gods, and devoting themselves to those things by which the body only is adorned, and nourished, and delighted, they sought eternal death for themselves, together with their gods and goods relating to the body, because all bodies are subject to death.
