Do you believe Christians should have an in-group tribal mentality? The way Muslims have with their concept of the global Islamic Ummah?
It might be a bit harsh, but more than half of the people concerned with Palestine would not care if Palestine was not Muslim and instead was Buddhist or Atheist. They care specifically because it is a Muslim against non-Muslim conflict with Arabs and a global narrative. How many Islamic groups cared about the Vietnam War? Almost none.
So do you believe having a sort of globally connected brotherhood through faith might be useful to believers of Christ? Especially when atrocities begin?
Especially in this secular era where most people don't see faith as anything other than a personal conviction.
