I answer that, Even, as in the blessed in heaven there will be most perfect charity, so in the damned there will be the most perfect hate.
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 AquinasWhen the devil is called the god of this world, it is not because he made it, but because we serve him with our worldliness.
