Archbishop Bob Duncan has responded quietly and gently to the recent report from the C of E Archbishops about the relationship between ACNA and the C of E. ++Bob isn't reading too much into the report save for quiet encouragement for ACNA to continue on the course it is on. Reading around the traps I see the opponents of ACNA are saying "nothing changes for ACNA" and give a general impression of business as usual.
I think that is a mistake. The Anglican Communion is going through a convulsion, if not a revolution. No one knows what the new Anglican Communion will be like (e.g. will it be united around a Covenant or not?) but some signs are being given us. One sign is that the Anglican Communion is renewing its commitment to doctrine as part of the definition of being Anglican. Sure, some want doctrine to be wholly determinative for that definition and some are resistant to any totalisation of doctrine in the definition of being Anglican, with quite a lot of resulting 'noise' on the internet. But the noisy ones may miss the underlying trend towards greater importance being placed on doctrine as something Anglicans hold to rather than something we proudly display our doubts and scepticism about.
Just taking that one factor, I suggest ACNA is staying on course to be a good fit with the Anglican Communion when it is through its convulsion. For the record: I am not simultaneously arguing that ACCan and TEC are going to fail to be a good fit; they have as much opportunity as any Western Anglican church to renew their acquaintance with Anglican doctrine.
But I am arguing that any Anglican Communion church that thinks future membership of the Communion need merely rest on the laurels of "historic" commitments to the Communion should think again. The Communion is moving through its present convulsion to a point where it is going to be less interested in churches claiming they have always been part of the Communion and more interested in churches claiming to be Anglican in doctrine and in practice.
