She causes nothing but demonstration (chaos): Homeless and divided

Someone assumes here that there is a house or a home? This (her antiquity to avoid the boring truth) leads to homelessness

https://biblehub.com/luke/12-52.htm

Look closely:

There is a Father

There is a Son

There is a Daughter 

There is a Mother

Mother-in-law and Daughter-in-law?

Is it 4 or 6 in a household?

The Daughter is the Daughter-in-law (5)

the Son's Wife living in the home. 

Why are they in conflict?
