I had a great weekend at my sending church's houseparty in Derbyshire. The speaker was Tim Hanson, vicar of Wharton.
His main point was that the unity between individuals in the church is how God reminds Satan of Satan's past defeat and future destruction at the hands of Jesus, from Ephesians 3:10-11, then applied through large chunks of Ephesians to details of our individual and corporate lives. It certainly seems a legitimate take on Ephesians, and I don't recall seeing Ephesians through that lens before.
Oh, and for those I spoke to about my concern in getting back past Silverstone, the journey was fine and just over 2 hours - I went via the M42, and then cross-country from Banbury.
