Whether the Communion splits or stays together does not depend on one man, let alone the Archbishop of Canterbury. But I am more than prepared to say that he is more influential on the future of the Communion than many men or women. Perhaps, one might argue, he is more important than all the Anglican bloggers put together :) (Not that we are much of a force. We rarely agree with each other).
Anyway, we should keep in touch with ++Justin's thinking and what better way than via the reporting of Charles Moore.
