Over the last few years there's been increasing adoption of the idea of the 'person of peace' mentioned by Jesus when sending out the 12 (Matt 10 and Luke 10) as being a person with whom one should share the gospel. While I can see the adaptation, this is not at all how the passage reads to me, and is much more about staying with someone with integrity and honesty while performing an itinerant ministry.
In one sense it's semantics, but in another it seems to me to be seriously misrepresenting scripture. I'm also not comfy with the idea that if someone isn't open to hear about Jesus then you should "shake the dust off your feet" over them (the original meaning seems to have been effectively a curse) and move on, that accompanies the PoP theology.
I'm coming to dislike contrived theology.
