This article is hardly bad mouthing Anglicans leave alone the various other non-Catholic groups. It makes sense that the Queen who is right now the head of the CoE in England, the CoI in Northern Ireland and the Church of Scotland in Scotland, cannot be a practising Catholic and be at the same time a Presbyterian in Scotland, an Anglican in England etc. Some solution needs to be made -- disestablishmentarianism is the solution.
But that will not stop the CoE's decline which is already, sadly, terminal.
