Have you seen that video of Orthodox priests brawling in the Church of the Nativity? It's sad and disturbing, but it's not surprising...

One of the more surprising, and personally saddest things I
have encountered in my trips to the Holy Land, is the encounter
with Orthodox clergy. While I had been trained to expect tensions
between Jews and Arabs, my experience involving the Orthodox clergy
was actually the most tense and shocking. It also surprised me
since, speaking for myself, I have always had great admiration for
the beautiful liturgies of the Orthodox. And, while I know little
of the internal realities of those Churches, I have always hoped
for reunion. My experiences in the Holy Land showed me very clearly
how difficult and unlikely such a reunion may be. A few personal
stories.
