Although the idea of a large group of students eating in the same dining hall and praying in the same building does not seem particularly problematic, the intersection of very different religious backgrounds in those settings has presented a challenge for Hillel coordinators.

"People's expression of Judaism can be so different to the extent where there might be conflict," Rosenberg says.

On the broadest level, Hillel organizers have long sought to accommodate people of different religious backgrounds by offering separate religious services for Orthodox, Conservative and Reform Jews.

And by offering kosher meals, Hillel provides a place for dining that is open to all types of Jews.

But, as Rosenberg suggests, differences in observance can lead to controversy.

Recently, for example, some Hillel members have debated whether or not soda machines in the building should be left running during the Sabbath.

Others have argued over whether women should be allowed to lead the grace after the Sabbath dinner--a debate that some Hillel regulars say has been especially volatile lately.
