Valerian of Cimiez

Therefore, dearly beloved, the rust is that worm which alone possesses the recesses of the human heart: the worm of envy and of avarice. But the thief is the devil. Believe this. To lay his plots against good deeds, he flatters us with the pomp of the world. To keep a man from sharing in the heavenly kingdom, he puts gold in his hands, silver before his eyes, gems about his neck. In this way he nourishes pride and by the goad of covetousness enkindles the desires of the flesh.
