I have a quoting urge.
I apologize for how long this might be, and for the fact that I must elide between a few important quotes... if you want to see the rest, read the book! We are reading about original sin and he delves into a discussion of community here.
"Humanity is not an aggregate of individuals but an organic unity, one race, one family. Angels, on the other hand, all stand side-by-side, independently of one another...God created all of us from one man (Acts 17:26); we are not a heap of souls piled on a piece of ground, but all blood relatives of one another, connected to one another by a host of ties, therefore conditioning one another and being conditioned by one another."
(a couple pages later)
"All the members of such a body can either be a blessing or a curse to one another, and increasingly so to the degree that they themselves are more outstanding and occupy a more pivotal place in the organism. Fathers, mothers, guardians, caretakers, teachers, professors, patrons, guides, princes, kings, and so on have the greatest influence on those under their jurisdiction. Their life and conduct decides the fortunes of their subordinates, elevates them and brings them to honor, or drags them down and pulls them along to destruction. The family of the drunkard is ruined and disgraced because of the father's sin. The family of a criminal is widely and for a long time identified and condemned along with him. A congregation languishes under the faithless conduct of a pastor. A people decline and are eventually destroyed as a result of the foolish policies of a king. 'In whatever thing the kings go crazy, the Achaeans [homer's greeks] are punished.' Among people there is a solidarity for good or ill: community in blessing and in judgment. We stand on the shoulders of earlier generations and inherit the things they have accumulated in the way of material and spiritual wealth.
We enter into their labors, rest on their laurels, enjoy the things they have frequently aquired at great cost. We receive all this undeservedly, without having asked for it. It is waiting for us at our birth; it is bequeathed to us by grace."
