"Liminality"

I came across some writings from Victor Turner on "liminality", then I came across the following piece in Alan Hirsch's blog which uses stuff from Roxburgh to also consier "liminalty".

It is worthy to note again that the church in the West is facing a massive adaptive challenge: positively in the form of compelling opportunity and negatively in the form of rapid, discontinuous change. These twin challenges comprise a considerable threat to Christianity locked as it is into the prevailing Constantinian (Christendom) form of church with all its associated institutional rigidity. We are in a situation of what Roxburgh calls ‘liminality’. Liminality in his view is the transition from one fundamental form of the church to another … Environments of discontinuous change require adaptive organizations and leadership. … the missionary situation requires a pioneering and innovative mode of leadership to help the church negotiate the new territory in which it finds itself. This is clear enough when we consider the Emerging Missional Church which relies heavily on an innovative pioneering spirit … But it is equally true for established churches.
