A juicy tidbit from N.T. Wright, one of my favorite New Testament scholars:
Thus the church that takes sacred space seriously (not as a retreat from the world but as a bridgehead into it) will go straight from worshiping in the sanctuary to debating in the council chamber; to discussing matters of town planning, of harmonizing and humanizing beauty in architecture, green spaces, and road traffic schemes; and to environmental work, creative and healthy farming methods, and proper use of resources. If it is true, as I have argued, that the whole world is now God's holy land, we must not rest as long as that land is spoiled and defaced. This is not an extra to the church's mission. It is central.
The church that takes seriously the fact that Jesus is Lord of all will not just celebrate quietly every time we write the date on a letter or document, will not just set aside Sunday as far as humanly and socially possible as a celebration of God's new creation, will not just seek to order its own life in an appropriate rhythm of worship and work. Such a church will also seek to bring wisdom to the rhythms of work in offices and shops, in local government, in civic holidays, and in the shaping of public life.
