blog on the value of traditions in the church and some of the comments reminded me of the model (above) I developed for one of my essays when I was training. The Anglican church is based on Scripture, Tradition and Reason (Richard Hooker) with the Evangelical, Anglo Catholic and Liberal traditions respectively being more drawn to each. The Lambeth Quadrilateral sits somewhere in the centre of this. Around each is an inner circle of those who would be accepted to be of that particular tradition, and a wider circle of those who would be accepted as having a faith, but not of that tradition. Unfortunately there are areas where one wing would accept people and others would not.
If you accept that Anglicanism is based on Scripture, Tradition and Reason then almost by definition those who subscribe wholly to one of those are in some sense on the edge. There are of course other denominations which do not accept that basis, and hence which would not see, for example, a sola scriptura approach as being on the edge - but then I would argue that it is not Anglican!
