Psalms 53:1

To such people the word of the prophet can be applied most fittingly: "The fool says in his heart, there is no God." They who say that nothing is seen by God almost deprive him of eyes and even take away substance from him. For when they say he sees nothing, they say he does not exist at all. Although no evil deed is based on reason, because crime cannot be joined with reason, there is no sin, I believe, more irrational or senseless. What is more insane than for anybody, who does not deny that God is the creator of the universe, to deny his governance? How does he admit that God created the world and neglects what he created? As if, indeed, he took pains in creating all things so that he would neglect what he had made!

"The unwise man hath said in his heart, There is no God" (ver. 1). Such sort is it of men amid whom is pained and groaneth the Body of Christ. If such is this sort of men, of not many do we travail; as far as seemeth to occur to our thoughts, very few there are; and a difficult thing it is to meet with a man that saith in his heart, "There is no God;" nevertheless, so few there are, that, fearing amid the many to say this, in their heart they say it, for that with mouth to say it they dare not. Not much then is that which we are bid to endure, hardly is it found: uncommon is that sort of men that say in their heart, "There is no God." But, if it be examined in another sense, is not that found to be in more men, which we supposed to be in men few and uncommon, and almost in none? Let them come forth into the midst that live evil lives, let us look into the doings of profligate, daring, and wicked men, of whom there is a great multitude; who foster day by day their sins, who, their acts having been changed into habit, have even lost sense of shame: this is so great a multitude of men, that the Body of Christ, set amid them, scarce dareth to censure that which it is not constrained to commit, and deemeth it a great matter for itself that the integrity of innocence be preserved in not doing that which now, by habit, either it doth not dare to blame, or if it shall have dared, there breaketh out the censure and recrimination of them that live evil lives, more readily than the free voice of them that live good lives. And those men are such as say in their heart, "There is no God." Such men I am confuting. Whence confuting? That their doings please God, they judge. He doth not therefore affirm, "some say," but "The unwise man hath said in his heart, There is no God." Which men do so far believe there is a God, that the same God they judge with what they do to be pleased. But if thou being wise dost perceive, how "the unwise man hath said in his heart, There is no God," if thou give heed, if thou understand, if thou examine; he that thinketh that evil doings please God, Him he doth not think to be God. For if God is, He is just; if He is just, injustice displeaseth Him, iniquity displeaseth. But thou, when thou thinkest that iniquity pleaseth Him, dost deny God. For if God is one Whom iniquity displeaseth, but God seemeth not to thee to be one whom iniquity…
