The Covenant is dead, and so is the Communion
The Anglican Communion is not a Church. This is where Archbishop Rowan Williams keeps making his mistake, why he talks about dioceses and then his primacy, and forgets that, like it or not, the local Churches organise the dioceses and have their own primacy. His method is to bind the bishops and his office via a Covenant to strengthen the Instruments of Communion: however, again and again, actual Churches have rejected its narrow focus and more disciplinarian features.
