I embark on this subject tentatively. With trepidation, because I am neither a missiologist nor an ecclesiologist. Nor did I know, when I agreed to the invitation which Mark Hill put so persuasively over a year ago, what would be happening in the Church in the autumn of 2020. Yet it is in many ways a good time to be having a discussion about mission and structure. As I am sure you know, there is work under way on both these questions within the House of Bishops and beyond. Archbishop Stephen Cottrell is leading some work on a vision and strategy for the Church of England for the 2020s. Bishop Nick Baines is leading a group looking at the governance of the national church institutions, in support of that work.
