Thanks GKC but narcissisism can be contagious!
Which Elizabethan compromise? There has been two Elizabethan ages and both have come at turning points of English/British history and critical to development of the CoE. The current age is longer but not yet accumulate the antiquity that the English loves so much.
The first Elizabethan compromise was definitely successful in keeping the the CoE unitary. The current compromise (though I doubt Her Majesty has much of a hand in it) seems (from my perspective) to swept things under the carpet. At each Lambeth Conference, there is this big build-up and then nothing happens and all the bishops go home with a diplomatic choice of words. And they go home and proceed on the exact same path as before the Conference.
Part of it is of course due to the nature and differences in ecclesiology and church polity in the Anglican Communion. Each church is autonomous and communion with a new bishop is taken as automatic. This differs from the Catholics (where individual churches are not autonomous) or the Orthodox (where, correct me if I am wrong Peter, bishops can still make individual decisions based on their idea of the orthodoxy of the new bishop). Increasingly, conservative bishops are being forced to evaluate new bishops to define communion and I think, one day there will be a break.
I think the old categorisations of Anglicans as High and Low Church is also obsolete, if not misleading. The difference is now between liberals and (for want of a better word) conservatives, who may be High Church or Evangelical Anglicans. The category of Anglo-Catholics is probably useful in identifying those who would most likely call up Rome, if push comes to a shove.
To me, the surprise is that the Anglican Communion still remains unitary today, with only the odd ACNA here and there. But that body of common truths that hold the Communion together has shrunk and it seems likely to continue to shrink. Will there be a time when the body of common truths has shrunk to the point where one cannot call it a Communion of churches any longer? Will there be different degrees of communion with the lower degree of communion being attributed to churches formerly in communion? Will that open up the door to different degrees of communion being attributed to churches that was never in communion? In a way, it further extends a sense of communion heirarchy that already exists with the CoE seeing (say) TEC as having a higher degree of communion than with (say) Old Catholics, as having a higher degree of communion than with (say) Roman Catholics, as having a higher degree of communion than with (say) Methodists, etc, etc.
Will it advance the cause of ecumenism and church unions or will it set it back?
There are definitely lessons here for the Catholic Church, but I am afraid different Catholics will see different lessons that will only serve to confirm the views they already hold. This debate will run and run. Maybe the Holy Spirit guide it well.
