This is also pretty dependent upon the campus culture of your school, the chapter you join, etc. Just be upfront but not confrontational about your requirements, and be open to their feedback. See if there is a way to reconcile your obligations to the sorority with your obligations to your faith. I am a practicing Catholic, and while we don't have Sabbath restrictions per say, there were a few days during my pledgeship that fell on holy days of obligation. I talked with my pledge educator and told her about the requirements I had, and made arrangements to make up/compensate for what I missed. It was not really a big deal.

If what psusue is close to how you keep the Sabbath (doing family/community events and service etc) perhaps you can bring that up to the chapter as a way of scheduling things that are part of programming anyways and also fit in with your faith practices?
