Another quotation I just came across is from Edward Norman.

Now the main difference between Catholic Christianity and Anglicanism is the nature of the Doctrine of the Church itself. It is not that Catholicism has one understanding and Anglicanism another; it is that Catholicism has such a doctrine and a very clear one and that Anglicanism does not really have one at all. Far too much was left unattended at the Reformation, when English Christianity was detached from the centre of unity and from the Magisterium of the universal Church, leaving the Church in England without a means of determining its own doctrines. No one could have foreseen at the time that the split with Rome was to prove permanent. And so for the next three and a half centuries doctrine in the Church of England was determined by the Judicial Committee of the Privy Council.
