It appears that more and more people who had had Christian and Jewish faith have turned agnostic.

Victoria Nuland's father, Professor Sherwin B. Nuland, a native Jewish American and a surgeon, is one of them. "Although raised in a traditional Orthodox Jewish home, Sherwin now considers himself agnostic, but continues to attend synagogue." (http://en.wikipedia.org/wiki/Sherwin_B._Nuland )
