When the devil is called the god of this world, it is not because he made it, but because we serve him with our worldliness.
Thomas AquinasHe who is drawn to something desirable does not desire to have it as a thought but as a thing.
Thomas AquinasSloth is sluggishness of the mind which neglects to begin good...it is evil in its effect, if it so oppresses man as to draw him away entirely from good deeds.
Thomas AquinasThe magnitude of the punishment matches the magnitude of the sin. Now a sin that is against God is infinite; the higher the person against whom it is committed, the graver the sin-it is more criminal to strike a head of state than a private citizen-and God is of infinite greatness. Therefore an infinite punishment is deserved for a sin committed against Him.
Thomas Aquinas
