The last presidential address of the ABC to the ACC (or any international Anglican gathering for that matter) has been given and the whole text is here.
I suggest reading it with this news item about the bits and pieces of ACC being gathered up for Indaba-ization (i.e. further talk on Hegelian lines) along with an un-Hegelian perceptive and frank interview of Philip Ashey by David Virtue.
++Rowan makes a good point or two about authority in his talk. The question is whether it is Christ-like talk or not. Christ certainly exhibited and encouraged enabling authority. But there was some corrective authority as well.
In particular we might ask of a phrase ++Rowan himself uses, "our common imbecility," whether that aspect of humanity ever needs the firm hand of corrective authority to deal with it.
