Christendom and Kingdom of God Part II

So if the Kingdom of God is the new focus of post-Christendom Christianity what does this mean?

I have a proposal: where as the old Christendom paradigm was based on a Roman Imperial M.O. ("Constantinian") the new paradigm is not post-Christendom but rather a new Christendom paradigm based not on the Roman Imperial M.O. but a liberal-socialist model (not quite marxist or anarchist but a stange blend of the two, with classical liberalism on the side).

Why?

Usually the language of KoG is used to associate the notions of social justice and politicial ciritque with the gospel. Although I believe that justice and critique are part of the gospel (even the word 'gospel' contained political connotations in the first century Roman world) I wonder if such a strong association between the KoG and a radical socialist Christendom has potential. Potential to change paradigms and potential to expand a often highly individualized gospel based on justifying phantom sins (by phantom sins I mean preaching forgiveness without going into the depths of what we need forgiveness for or the outcome of forgiveness).

And is this the right potential anyways?

I think there is more to say about this new Christendom paradigm, which draws from the radical reformation but is distinct from it by rejecting it's two-worlds dualism.
