The Church of England as an institution still looks okay on the surface. Congregations may age and decline and parishes are amalgamated as clergy numbers reduce (while the bishops add to their number) but worship and parish life and the central structures continue to function. But look inside and underneath and pay close attention to events at local, national and international levels and things are not looking good. At local, national and international levels the church is lacking - the church lacks leaders with courage, prophetic vision and wisdom. The church lacks the integrity and insight to tell the story of creation and evolution and human potential revealed in the Bible and Jesus (if you know where to look).
In my experience, a paradigm change is taking place in the Church of England, difficult though it is to discern if you look at the central structures of the Church. Change is happening at parish level and in the many friends I have and networks I am part of. Many of my friends have abandoned attendance at or involvement with the Church, despairing of its teaching, worship and leadership and finding it no longer fit for purpose.
