Frame’s Evangelical Reunion has been a good read, first published in 1991. Frame takes to task a certain idolization of denominations and posits a way forward with less evangelical infighting.
And the other thing is Jordan’s Sociology of the Church. Jordan accomplishes Frame’s thesis and then for kicks writes an ecclesiology from Genesis 2. Didn’t you see that coming? The Church is at the center of the universe. The world is structured such that the church cannot but be at the center. It is not whether the nations will inherit our accomplishments, it’s rather: what will those accomplishments be? When churches are full of greed, the world is full of greed. When churches hire clowns to give pep talks, the world is full of clowns giving pep talks. This is because the Church is the garden transfigured on the mountain that is filling the earth. The rivers still flow out of the church and flood the world whether we know it or not. Litter costs a lot more than the sign says.
But the Church is geographical. That is the second greatest commandment.
