What avails noble birth to him whose life is disgraceful? Or, on the other hand, what hurt is a low origin to him who has the lustre of virtue? It is fitter that the parents of such a son should rejoice over him, than he over his parents. So do not you pride yourselves on having Abraham for your father, rather blush that you inherit his blood, but not his holiness. He who has no resemblance to his father is possibly the offspring of adultery. These words then only exclude boasting on account of birth.
