This is an interesting article, but I suspect it is taking a phenomena that is taking place in a few mega-churches and extrapolating further than is wise. A couple mega-churches dealing with splits does not imply a wide spread dissolution of the movement. From the view from here, there does not seem to be as much division as the author of the article claims. The
church first mentioned in the article is composed of five separate palaces. While the pastor is bemoaning a loss of unity and a loss to greater cultural forces, the congregation clearly surrendered to simple comforts and power a long long time ago to be able to build such remarkable and beautiful infrastructure near the steps of shocking inequities and poverty on the other side of the Potomic River. Rev. Platt does everything but look inward at his own failings as a Christian leader when bemoaning his own loss of influence.
The rest of the article is more of the same. A long list of pastors who wish their congregations would fall in line and accept the uncertainty of rejecting outside influences, but at the same time the pastors mourn the loss of their own comfort in leading people who simply acquiesce to them rather than to other political forces. Best of all they simply make up history and context to justify their sense of loss. For example, the so-called Christian takeover of Rome came to a head on a bloody battlefield at the Milvian Bridge as the result of recruiting armies from far away places combined with political machinations by Constantine rather than through a simple transition led by some peace loving hippies influencing the Roman populace by sharing flowers and hugs. And just as today, that movement was co-opted and perverted by non-believers as a way for them to gain power and legitimacy.
