You can read Peter Leithart’s recent thoughts on family, church, and society here, or below:
Christian political thought has historically gotten off on the wrong foot through misinterpretation of Genesis 1-2. Adam and Eve are taken as “family,” and hence the family becomes a “natural” institution. Families band together and soon there are cities and kingdoms, also natural institutions.
Augustine says this, and so, following him, does Isidore. And everyone of course follows Augustine and Isidore.
The church comes later, a top layer on nature, the supernatural society.
But the garden is not “home” but sanctuary; Adam and Eve are not “family” but worshiping community, created and placed in the place of God’s presence and offered the fruit of the tree of life.
There is no more natural society than the church.
