The first installment was an excellent essay by Michael Horton: How the Kingdom Comes.
The heart of Mathewes-Green's perspective on church and culture is summed up, I think, in this paragraph;
The culture, then, is like the weather. We may be able to influence it in modest ways, seeding the clouds, but it is a recipe for frustration to expect that we can direct it. Nor should we expect positive change without some simultaneous downturn in a different corner. Nor should we expect that any change will be permanent. The culture will always be shifting, and it will always be with us. God has not called us to change the weather. Our primary task as believers, and our best hope for lasting success, is to care for individuals caught up in the pounding storm.
She goes on to also discuss how we as believers are also affected by the weather:
But we must regretfully acknowledge that we, too, are shaped by the weather in ways we do not realize. Most worryingly, it has induced us to think that the public square is real life. We are preoccupied with that external world, when our Lord's warnings have much more to do with our intimate personal lives, down to the level of our thoughts.
So, when Christians gather, there's less talk about humility, patience, and the struggle against sin. Instead, there's near-obsessive emphasis on the need for a silver-bullet media product that will magically open the nation to faith in Jesus Christ. Usually, the product they crave is a movie. Now, I'm delighted that Christians are working in Hollywood; we should be salt and light in every community that exists, and so powerful a medium clearly merits our powerful stories. But it's telling that the media extravaganza so eagerly awaited is not a novel or a song, something an individual might undertake, but a movie: something that will require enormous physical and professional resources, millions of dollars, and, basically, work done by somebody else.
This focus on an external, public sign is contrary to the embodied mission of the church. Christ planned to attract people to himself through the transformed lives of his people. It's understandable that we feel chafed by what media giants say about us and the things we care about, and that we crave the chance to tell our own side of the story. It's as if the world's ballpark is ringed with billboards, and we rankle because we should have a billboard too. But if someone should actually see our billboard, and be intrigued, and walk in the door of a church, he would find that he had joined a community that was just creating another billboard.
Finally, I also think it's worth highlighting another area where she sees the church following the culture: in the tone of our interaction:
More serious, however, is a tone of voice we adopt from the culture: sarcastic, smart-alecky, jabbing, and self-righteous. We feel the sting of such treatment and give it right back; we feel anger or even wounded hatred toward those on the "other side." But God does not hate them; he loves them so much he sent his Son to die for them. We are told to pray for those who persecute us and to love our enemies. The weight of antagonistic and mocking big-media machinery is the closest thing we've got for practicing that difficult spiritual discipline. If we really love these enemies, we will want the best for them, the very best thing we have, which is the knowledge and love of God.
Smart-alecky speech doesn't even work. It may win applause, but it does not win hearts. It hardens the person who feels targeted, because he feels mocked and misrepresented. It increases bad feeling and anger. No one changed his mind on an issue because he was humiliated into it. In fact, we are misguided even to think of our opponents in the "culture wars" as enemies in the first place. They are not our enemies, but hostages of the Enemy. We have a common Enemy who seeks to destroy us both, by locking them in confusion and by luring us to self-righteous pomposity.
The whole essay is worth reading.
