Eusebius of Caesarea, on Ps 13:1

“Unto the end, a psalm for David. The fool hath said in his heart: There is no God, They are corrupt, and are become abominable in their ways: there is none that doth good, no not one.”

“Some have denied that there is a divine spirit altogether. They have openly professed that God is not the ruler of everything, that his name is nothing but empty and that he is of no substance. Others worship gods who do not exist, denying him who is God alone. Some suggest that indeed there is a God in name, but they contend that he does not oversee earthly matters or look on human affairs. In summary, therefore, all these people have come together into the single position of atheism (godlessness), believing that there is no God. Since they are not bold enough to announce this openly, they persuade themselves in their hearts, being foolish and senseless in the matter of truth, that God does not exist. (A natural understanding about God and the innate seeds of the instinct drive all of them to confess a recognition of God; they are not so bold to deny this fact with their lips, so they pretend to recognize him not as the only God but as an innumerable plurality.) … Their godless position is brought to light from their works (as indeed a tree is judged by its fruit), with their villainy and a way of living like it. They have poisoned their own spirit, betraying it to their bodies with whatever corruption, and as men act in madness with men and through whatever other monstrous and abominable acts, they defile their own selves. In this way it was shown that even if they mustered ten thousand gods, even if they blared out with their lips and confessed God governs all things, in their hearts, and really in their minds, there is not the least recognition of God. Such, therefore, was the life of these people before the advent of our Savior.”
