Lactantius

“ And as in uncultivated lands, before you begin to sow, the fields must be cleansed by tearing up the thorns and cutting off all the roots of trunks, so vices must first be thrust out from our souls, and then at length virtues must be implanted, from which the fruits of immortality, being engendered by the word of God, may spring up. ”

“ What we owe to man, therefore, is prescribed by that same divine law which teaches that whatever you render to man is rendered to God. But the root of justice, and the entire foundation of equity, is that you should not do that which you would be unwilling to suffer, but should measure the feelings of another by your own. ”

“ If it is an unpleasant thing to bear an injury, and he who has done it appears unjust, transfer to the person of another that which you feel respecting yourself, and to your own person that which you judge respecting another, and you will understand that you act as unjustly if you injure another as another would if he should injure you. ”
