Over the last few years I have been thinking about the different strands of the church and about whether we could express those relationships in a Venn diagram. Last few days I have been thinking more and come up with the following diagram.

Its quite deliberate that some groups overlap all core Christian beliefs and some do not... obviously one problem with this diagram is that each group defines core Christian beliefs differently. Nobody thinks that they are unsound themselves... but maybe the problem is the words sound and unsound. And what do we mean by 'core' anyhow?
