Hi Graham,
Someone once told me that the sentiment most oft repeated in both the Old and the New Testament is some version of the phrase, 'be not afraid.' EIther, 'do not fear' or 'don't be afraid' or something like that... I don't know if it's true -- never took the time to count it myself-- but, as a Christian, I like to believe it is true.
You didn't ask specifically , but I'll add it anyways: I think the worst thing about the New Testament is that it is considered finished and complete: some group of men in the 3rd century decided first what it is composed of and secondly that nothing evermore will be added to it. I'm thinking of some writings that were contemporary but excluded. I'm also thinking, for example of the story of Augustine, if not some of his writings, that would or should make up part of a continuing narrative. James wrote a letter to the twelve tribes scattered all over the world, so why shouldn't Augustines letters be included?
Just some thoughts. I'm looking forward to reading the upcoming parts of your series.
