Fr Jonathan at Conciliar Anglicanism posts on a post by Tobias Haller at In a Godward Direction. The former is headed "Anglicanism's Unique Doctrine" and the latter is titled "Thought for 06.30.11." Tobias comments on Fr Jonathan's post, in a debate on whether the latter has understood the former.
What interests me is, first, what Tobias Haller says about the Communion and Covenant; but secondly, with Fr Jonathan, whether there is anything unique to Anglican doctrine or not. (Tobias argues for a unique polity). I may take up what Haller says about the Communion and Covenant on another post, but for now I will confine interest to the possible uniqueness of Anglican doctrine.
With or without reading the two posts linked to above, is there a unique doctrinal contribution of Anglicanism to the theological life of the universal church?
I like Fr Jonathan's observation that some Anglicans, on all parts of the spectrum of our life, tend to think being Anglican is a convenient way of being Christian, or in the words used by many an evangelical Church of England preacher, our church is a good boat to fish from. Is that all there is to Anglicanism?
Debate and discussion on this particular matter is spreading, see, for instance, Creedal Christian.
