‘But whosoever shall say, Thou fool, shall be liable to the gehenna of fire.’ (Mat 5:22)
There are many who say and believe that this is too grievous and severe a judgement. But it is not. For is he who would deny the existence of his brother’s faculties of reason and thought, those characteristics by which we differ from the beasts, is such a man not deserving of gehenna? For he who reviles and insults, dissolves love; and when love is dissolved, all the virtues are destroyed along with it, just as when love is present it unites to itself all the virtues. Therefore, he who hurls insults, destroys all the virtues by tearing love to shreds, and rightly does he deserve the fire of hell.
