I've begun to view the bible in somewhat similar terms - the stuff Jesus said is the real important stuff; the rest is just commentary.
The church was founded on the teachings of Jesus. Some years later the apostles Paul, Peter, John and others wrote letters to some bits of the church and said other stuff. But that was supplemental to the basic gospel that the churches already knew. So (as I've said before) how come most 'confessions of faith' or equivalent are based on the supplemental writings?
I came across the term "Red Letter Christian" a week or two ago. I like the sound of it - its a group of Christians who seek to base their lives primarily on the teachings of Jesus ('cos in some bibles, the words spoken by Jesus are highlighted in red text). But I was slightly annoyed that when I looked into it further (Wikipedia, Google) that the term seems to be being exclusively used of certain politically active Christians in the USA, who stand against some of the policies of the Republican party, even though something like 4 out of 5 'evangelical Christians' tend to vote Republican.
Can we not divorce the idea from politics and just all pay more attention to the things that Jesus actually said?
ps I'm currently (and slowly) working my way through the gospels - to look again at what Jesus actually did (and didn't) say. Its taking me a while, but I'll have some thoughts to post on it eventually...
