“When a taste for sinful pleasures,”says St. Gregory, “takes possession of a heart, it thinks of nothing but how to gratify its inordinate desires.” We must, then, struggle against it from the beginning by repelling every bad thought, for by such fuel is the flame of impurity fed. As wood nourishes fire, so our thoughts nourish our desires; and, consequently, if the former be good, charity will burn in our breast, but if they are bad the fire of lust will certainly be kindled.
