It begins by summarising the findings from recent research, which employs the principles of receptive ecumenism to explore women’s experiences of working in English churches. During this research, ‘mutual flourishing’ (as described in the ‘Five Guiding Principles’) was identified repeatedly, as an area of practice which is a ‘live’ wound in the life of the Church of England.

The final phase moves on to suggest what it might mean in practice to appropriate Thomas’s theology of friendship in the life of the Church of England.
