How can you be christian if your beliefs can dispense with Christ altogether when you reduce them down.
I wonder then how you are defining Christian here.
It strikes me that Steve takes his faith quite seriously since its restoration through liberal christianity seemed very important to him.
It strikes me that Steve is struggling to rescue something of value in the Christian tradition, in the hope that (particularly) the Anglican Church may be able to accommodate all the views of the Critical Period, and particularly the later speculations of Paul Tillich, Bonhoeffer and even more non-traditionalist thinkers such as Don Cupitt, Jack Spong and indeed, Richard Holloway.
When he finally does decide to come down on one side of the fence or the other, I suspect it will not be too close to your own cherished 'ground of belief' (to misquote Tillich).
