Genesis 18 (xix)

Married people should know that there is no greater and more useful work than they might do for God, Christendom, the rest of the world, themselves and their children than to bring up their children correctly. For this is the most direct path to Heaven. (...) But, likewise, there is no easier way to earn Hell than through your own children. There is no more damaging work that could be done by parents than to neglect their children, to let them curse, swear, learn shameful words and songs and to let them live according to their own will. (...) There is no greater scandal in Christendom than the neglect of children. (...) A false love of nature blinds parents, so that they give greater attention to the flesh of their own children than they do to their souls. Children are a wonderful and eternal treasure and God has commanded parents to look after them, so that the Devil, the World and the Flesh do not steal them and destroy them. At death and at the Last Judgement, a severe reckoning will be demanded.
