The BBC Radio programme, Sunday had two items about this.
The programme can be found here including a downloadable podcast.
First, Stephen Bates of the Guardian gave a brief outline of the significance of the GAFCON announcement. This is 6 minutes into the programme, and lasts for about 4 minutes.
Then, starting at about 33.5 minutes in, and running to the end of the programme, i.e. for about 10 minutes, there is a longer discussion about this. It features in turn the retired archbishop Lord Carey, then Bishop Martyn Minns of ACNA and GAFCON, and then Bishop Graham Kings of the Church of England.
This should be listened to in full.
Bear in mind that ACNA is not a member of the Anglican Communion although it is a member of GAFCON.
Graham Kings noted that GAFCON is not the same as the Global South Anglican movement, and at least three GSA primates (Chew of SE Asia, Anis of Jerusalem and the Middle East, and Ernest of the Indian Ocean) are themselves moderates in favour of the Covenant. He also argued that the GAFCON primates cannot speak for their provinces until their provinces have actually considered the Covenant themselves.
It also appeared from what he said that the Sudan province, whose primate was a member of the GAFCON council (is he still?), has already voted at least once, if not yet definitively, in favour of the Covenant.
Confused yet? You should be.
See the Comments below for links to some partial transcripts.
Anglican Mainstream has very helpfully transcribed more of the programme, see BBC interview with Bishop Minns on Gafcon Primates’ Statement.
And Fulcrum has transcribed the whole of Bishop Kings’ remarks at Interview with Graham Kings.
There is now an even fuller set of transcripts in the Comments on an article at Titusonenine, starting here (and in the following comments).
