Good post, btw, I wish I was not such a late-comer to it!
I consider myself "born again" I guess in sort of the evangelical sense, although for me the journey for me was from fundamentalism/pentecostalism to where I am today. For me, it is an experience/process that goes beyond mere assent to a set of cognitive ideas and ethical/moral ideals. While I do hold to fairly classical Christology in the orthodox sense, there certainly has been an iconoclastic thing going on with me the past few years where I have painfully realized that many things I thought were "christian", certainly were not: infallibility of the written Bible, strict doctrinal assertions about salvation, assertions that there would only be Christians in heaven, American "manifest destiny", conservative religio-political ideals, etc. But I do not believe that there should be a marraige of "progressive" Christian beliefs with a blanket dismissal of religious experience. A life of prayer/meditation and piety is still important, and perhaps something that should be wrested from fundamentalism as well.
