I met a number of Palestinian Christians while I was in Israel. The Christians in Israel are mostly Arab, and they live mostly in the Palestinian territory. They speak a language that is very closely related to Aramaic. They are not tied to either the Jews or Muslims, so they're in a very difficult situation. Most no longer feel safe, and their numbers have dwindled dramatically.

The Wikipedia article on Palestinian Christians is here (click). Arab Christians, including the Palestinian Christians, are an interesting group of people. They claim roots that go back to the early days of the Christian Church, before Islam was founded. In Palestine/Israel, the best-known Arab Christian communities are in Nazareth and Bethlehem.

"Driven out" may be too dramatic a term. Arab Christians are leaving their home lands on their own accord, because they no longer feel safe. Many have been killed or mistreated because of their faith, and because they are no longer trusted by their Muslim neighbors.

This article from the Jerusalem Post seems more than a little slanted, but it does give interesting information.
