If such a document actually exists, I submit the signatory's are not exactly those whom true Christians would proclaim as “their leaders” largely because Christians consider Jesus Christ their “leader” and being Christian, need no further human intervention in the chain of command between themselves and the one true God.
But nice try!
Note: not one Russian Orthodox leader signed this piece of trash. Russians know about Moslems and have been fighting them for centuries. The answer is to convert them, not bow down to them.
It ain’t signatures, but it’s a copy of the ad run in the NYT on 18 Nov 07: http://www.acommonword.com/lib/downloads/fullpageadbold18.pdf
