This is a book about culture - about what culture is, God's role in culture, and what our actions as Christians should be, in roughly that order. I found it to be a helpful book in understanding what culture is and how to affect it, a thought-provoking book when it examined scripture through the lens of culture, and an encouraging book when discussing how we personally can and should act.
The author begins by removing from us the common idea that we can even talk about "the culture" in a simple monolithic way, or that it would be helpful to do so if we could. Rather, he says, a culture is its pieces, is its cultural goods - the roadways, the foods, the institutions, and more. Broadly speaking, a cultural good is something that changes the boundaries of the possible and the impossible - the telephone makes it possible for you to speak to your family when far from them, and may also make it impossible (in some jobs) to ever be really off-work. If we want to have an effect on culture, we should drop this vague talk about "changing the culture" - we need to interact with it specifically, with these cultural goods.
But how should we interact with culture? There are actually many responses we can have to culture - we can condemn culture, critique culture, copy culture, consume culture, or cultivate and create culture. Cultivation and creation go together because no cultural good exists in a vacuum - it always builds in some way on what has come before it. At times, any one of these might be the proper response to some cultural good, but creation is particularly important because culture only changes as new cultural goods displace old ones.
After discussing culture in general, Crouch turns to the Bible, and walks us from Genesis to Revelation and presents the Biblical story as a story about culture. This is the part of the book I enjoyed the most. Starting in Genesis, we are told that man is made in the image of God, an image that surely at least includes God's creative aspect. In Genesis 2, we find Adam in a garden - a garden is not just nature, but already nature + culture. Culture too is one of God's gifts to man. We also see God making room for man's own creativity - instead of simply telling Adam the name of every creature He makes it Adam's choice.
The cultural story continues through scripture. Later, God chooses the nation of Israel, creates for them a unique culture through the Levitical laws and a unique cultural vocation - living in total dependence on Him. Then, He sets them in the well-trafficked Jordan valley, making sure that Israel's unique cultural vocation would be lived out in full view of the surrounding nations. Later still, in Jesus we meet the single greatest culture-affecter of all time, and it is worth noting that many of the personal changes Jesus encourages are to be accomplished by cultural changes - prayer is to be in quiet rooms instead of on the street, for example. Finally, at the end of the story, in Revelation, the new Jerusalem is revealed - not a garden as in Genesis, but a city, that place where cultures have their fullest expression. And, Crouch argues, many of the cultural goods we are so familiar with today will still be there, in redeemed form, and it is worth asking ourselves if the goods we create today will have a chance at making it into the New Jerusalem.
The middle section of the book, it should be said, will also be the most controversial, especially for readers with a more conservative view of scripture. Crouch states quite plainly, for example, that he views Genesis 1-11 as "less a finely documented history than a story that invites our trust." He does, certainly, trust these chapters enough to draw many lessons from them. And he later emphasizes the importance of the fact that "the Christian faith is a historical faith."
The final third of the book discusses how we are to go about in our calling to culture, and begins with a shot of humility - the first chapter is titled "Why We Can't Change the World." To change the world in this context means to create or modify some cultural good in a way that affects the horizons of possiblity and impossiblity for everyone - a difficult feat. Furthermore, Crouch says, there are no "sufficient conditions" for a world-changing cultural good - in other words, you simply cannot know ahead of time if your creation will have the effect and reach you desire.
We can, however, certainly have a more local effect on culture, and for that we need three things - power, community, and grace. Power is the ability to propose a new cultural good - but power also comes with risks, and is alluring and corrupting. So how should we act as Christians? Crouch has several suggestions, but perhaps they can be summarized in saying that we should choose to use power in ways that rob it of its temptation - specifically, by exercising service and stewardship.
But, even with power, culture is also rarely created alone. Instead, we need a community, and this community tends to take the form of concentric circles of people - Crouch calls them the 3, the 12, and the 120. He gives the example of a corporation, in which the ~3 might be the CEO, COO, CIO, and CFO, the 12 would be the board of directors, and the 120 would be the rest of the key staff. This numerical pattern has Biblical parallels as well - the Synoptic gospels stress the roles of Peter, James, and John around Jesus. Beyond them there are the remaining 12 disciples, and there are indications of a larger group as well - Jesus sends out 70 disciples to declare the coming of the kingdom in Luke 10, for example.
Finally, we need grace. God is at work in human culture, so supernaturally abundant results are possible every time we create a new cultural good. To find your personal calling in culture, Crouch suggests you ask yourself a question - "Where do you experience grace - divine multiplication that far exceeds your efforts."
