Clement of Alexandria

The ancient race was perverse and hard-hearted; but the band of infants, the new people which we are, is delicate as a child. On account of the hearts of the innocent, the apostle, in the Epistle to the Romans, owns that he rejoices, and furnishes a kind of definition of children, so to speak, when he says, "I would have you wise toward good, but simple towards evil."

On account of the hearts of the innocent, the apostle, in the Epistle to the Romans, owns that he rejoices, and furnishes a kind of definition of children, so to speak, when he says, "I would have you wise toward good, but simple towards evil." ...But if, which is rather the true sense, they themselves understand the designation children of simple ones, we glory in the name. For the new minds, which have newly become wise, which have sprung into being according to the new covenant, are infantile in the old folly.
