The announcements have been made. So have initial responses. (Check out, e.g. Titus One Nine for posts, and many comments from supporters and detractors). Much of the story of the new Anglican province for North America lies in the future. Two important questions to be answered in the future are these:
(i) numbers matter: will the province grow significantly beyond its estimated 100 000 members? AND will TEC continue its estimated decline of a 1000 members a week from an estimated 2.4 million members?
If TEC stops haemorrhaging and the new province does not significantly grow TEC 'wins', but if TEC continues to decline and the new province grows, then one day the latter's aim to replace TEC will be achieved.
(ii) how will this body which has honestly declared itself to be an ecclesial community of many prayer books, ordination policies, and approaches to orthodoxy (i.e. Anglo-Catholic, evangelical, charismatic) resolve internal disagreement?
Obviously there is huge goodwill at present, and a remarkable unity of purpose given some previous disunity between 'non-TEC' Anglican groupings in North America. But in 2028 or 2048 will the same goodwill exist?
My humble suggestion is that significant theological, structural and constitutional work within the new province begins now in order to meet the inevitable challenges of the future.
