Chapter 4 of CSG Book 7 is blunt that blessed families should establish rules, standards of education, and a code of conduct rather than assume good intentions will be enough. The warning is not mostly about sudden rebellion. It is about drift.
The chapter treats habit as a spiritual force. If a family does not make its norms explicit, the surrounding culture supplies them anyway through speech, scheduling, anger, consumption, and default priorities. Household life always has a liturgy. The question is whether it is chosen or inherited unconsciously.
This makes family tradition more than nostalgia. It is a defensive and formative structure that keeps a household from becoming whatever the ambient environment most easily produces.
