The question is more complicated than the forum gives answer. We believe the true God to be Triune, and rejecting that is like rejecting the Son. That said, there is the Logos concept that various peoples in various places have different parts of the Logos and light. The Jews, naturally, have quite a bit of the Logos, but have not accepted the Trinity (I say "not accepted," because it was never there in Judaism).
I could see it in that sense, but Orthodoxy is very exclusivist, and I was interpreting the poll in the most absolute sense, which wouldn't include the Logos concept. If I include the Logos concept, then yes, I see God working to some degree in every religion, and would see a good bit in Judaism.
Perhaps I should have been more verbose...
