Greg Forster has some helpful comments on how social structures are rooted in Creation while also being shaped by human action. This means that social structures are rooted in the creational order but human action can twist them in accord with the Fall or press them back toward something that conforms to God’s law.
We must avoid two errors when thinking about social structures. The first error is thinking of them as arbitrary constructs of individual human decisions. This implies that there are no limits on how social structures can be changed. We raise children in families now, but if we all decided to live differently, we could just as easily create massive nurseries and drop off all our babies there at birth. We have an economy based on ownership and exchange now, but if we all decided to live differently, we could just as easily redistribute all property to the people we think should have it, or abolish property and live communally. This is the error I described earlier as naiveté about the social nature of human beings. . . . Admittedly, there is something mysterious about this. It certainly seems like social structures ought to be infinitely changeable if they are only the result of human action. But in fact, they make no sense to us if they’re arbitrary. If we can rearrange parenthood or ownership at will just by deciding to do so, then really there is no such thing as parenthood or ownership. The reason is simple: social relationships are embedded permanently in our nature as human beings. They’re like reason and morality, which are also embedded in our nature. You can’t think logically unless you first assume, without argument, that logic is valid. You can’t think morally unless you first assume, without argument, that there is such a thing as right and wrong. Similarly, you can’t think socially unless you first assume, without argument, that social systems are real and not arbitrary. The other error to avoid is treating social structures as though they were not a result of human action at all. This implies they can’t be changed, that they’re mechanical forces that stand outside our world. They control us, but we have no power to control them. I’ve already hinted at this error, when I commented that there’s no magical force outside human will that makes people live this way.

Sinclair Ferguson uses the Marrow controversy in 18th century Scotland as a historical lens through which to examine the issues of legalism, antinomianism, and assurance. Ferguson’s thesis, as reflected in the title of the book, is that both legalists and antinomians err in separating the benefits of Christ from Christ himself. The solution to both is to not seek the benefits of Christ apart from the person of Christ. In all, this is a helpful book full of interesting history and insightful theology. I think the one improvement could be situating the response of Boston and the Marrow men in the broader context of Reformed theology. Did they respond similarly or differently to these problems than Reformed theologians in other times and places? In the multitude of historical counselors there is oftentimes safety.
