#57 Godly Administration of Household, Children, Parents
The work of a married woman is not continuous praying and fasting, but the godly administration of children and the household, and the taking care of parents, as St. Paul says [I Tim. 5:4]. (Luther’s Works, v. 52, p.124)
#58 Like Our Parents We Beget and Rear Children
So I say in this case too: We were all created to do as our parents have done, to beget and rear children. This is a duty which God has laid upon us, commanded, and implanted in us, as is proved by our bodily members, our daily emotions, and the example of all mankind. (Luther’s Works, v. 45 p.155)
