Lactantius

“ Afterwards Epicurus said that there was indeed a God, because it was necessary that there should be in the world some being of surpassing excellence, distinction, and blessedness; yet that there was no providence, and thus that the world itself was ordered by no plan, nor art, nor workmanship, but that the universe was made up of certain minute and indivisible seeds. ”

“ When the philosophers of former times had agreed in their opinions respecting providence, and there was no doubt but that the world was set in order by God and reason, and was governed by reason, Protagoras, in the times of Socrates, was the first of all who said that it was not clear to him whether there was any divinity or not. ”

“ For if there is a God, as God He is manifestly provident; nor can divinity be attributed to Him in any other way than if He retains the past, and knows the present, and foresees the future. Therefore, in taking away providence, he also denied the existence of God. But when he openly acknowledged the existence of God, at the same time he also admitted His providence for the one cannot exist at all, or be understood, without the other. ”
