I don't see what I wrote as magisterial at all. Magisterial governance would be top-down; one person somewhere (or a committee) dictating to us all. Canterbury (or wherever) making the rules.
I'm talking about something more - lateral, for want of a better word. More collegial, or fraternal; collaborative. Synodical, even! Where it's not top-down but where we are bound to one another. We work together and consult together and have a shared sense of who we are and our mission in this world. Where the eye doesn't say to the hand, "I don't need you," (to borrow a phrase).
My concern is bigger than Australia but I'm trying to use Australia to illustrate to people that this isn't just a question of how closely or loosely provinces relate while each doing their own thing. This goes to the core of questions of who we are and what it means to be the church together, and how we navigate that in a global context. And yes, if we can't find a way forward together, for some of us it's not just going to be a distant sadness that we're no longer formally in communion with folks half a world away, but hard realities about whether parishes or dioceses even continue to exist.
