Attempts for unity in the Church of England?

There is one aspect of Archbishop Rowan Williams ministry as Archbishop of Canterbury that I have found interesting over the last few years. I believe that he considers his ministry as being one for unity, for the achievement of unity within the Anglican Communion. He is, of course, doing it in a very Anglican way. But I still find interesting the implicit recognition that the Anglican Communion needs in some way a minstry of unity, albeit one that is not accepted by everyone, rather than one of presiding over ever increasing difference.

Stella Maris post The Arcbhishops' Offer, in response to the attempt by the Archbishops of Canterbury and York to resolve a problem over the ordination of bishops in the Church of England, does bring to light the fundamental inadequacy of this very Anglican exercise.
