It is clear that Christianity does not exclude any of the ordinary human activities. St. Paul tells people to get on with their jobs. He even assumes that Christians may go to dinner parties, and, what is more, dinner parties given by pagans…Christianity does not simply replace our natural life and substitute a new one: it is rather a new organization which exploits, to its own supernatural ends, these natural materials…..There is no essential quarrel between the spiritual life and the human activities.
