Indeed Tony, the version given to us by Luke has a wonderful tension. It seem to be perfectly done. The disciples being re-narrated into being as they heard Jesus interpret the scriptures mede them realise that they were hearing the truth about themselves and their history, and yes, as you say, they knew that they were in the world but not of it. They had become part of the invitation to a better world, a new creation.

I totally agree that when referring to the foreigner, the outsider, James in not referring to the ‘social other’, but to the essential recognition of the other as other. My neighbour is all mankind.
