The usual suspects suspect ++Rowan is going to do nothing about a response to +Mary Glasspool's consecration.
I think the contrary.
++Rowan knows that the Primates Meeting early next year is likely to have a welter of "Got headache. Sorry cannot come." RSVPs if TEC's Primate is not disinvited, or similar.
I think he is getting the wording right on a crucial announcement. One that he need not hurry as there are plenty of months to go.
Whether the announcement is that ++KJS is actually disinvited; or that all the others are invited to a pre-Primates Meeting, it will be significant. And it will signal that ++Rowan gets it that the Communion has, perhaps, one chance left of a semblance of its former life and strength continuing into the future.
