Open Doors has published its 2012 list of 50 countries where Christians are most likely to be persecuted (hat tip to Cranmer for drawing attention to this). I found Open Door's list interesting for several reasons. First, although we hear constantly from certain quarters that Israel systematically persecutes Arab Christians, Israel is not on the list. Second, the Palestinian Territories are on the list. Then there's the point raised by Cranmer: that Muslim countries constitute the vast majority of places where Christians are likely to face persecution.
So yes, Christianity is in decline all over the Middle East, but focusing on a Christian exodus from the Holy Land for anti-Israel political reasons while ignoring Muslim persecution and other factors is just silly. For the sake of Arab Christians in the region it's time all of us, regardless of our theological views on some issues, stop beating about the bush and be honest about the persecution of Christians in Muslim lands (and this includes some Christian Zionists who would do well to focus more on the plight of Christians across the Middle East, rather than give the impression of having little interest in Arab Christianity).
