It was clear that all four denominations were declining, but that in Wales, Scotland and the USA the Anglican churches were declining much faster than the Church of England. Both the C in W and the SEC had potential extinction dates about 2040, with ECUSA possibly lasting 10-15 years longer. Indeed, although the Church of England is declining, it is only on the margins of extinction if the current pattern remains, thus unlikely to face extinction this century.
Rather than just repeat the standard reasons given for church decline, in the light of the contrasts in decline patterns, I would rather look at a different question: What does the Church of England have, that the other three denominations do not, that may have helped reduce the effects of numerical decline?
Here are some suggestions, not exhaustive, and some may be a bit controversial….
