Brandeis Interfaith Group (BIG) exists to encourage interaction, service, and dialogue on campus amongst students of multiple faiths and belief systems. This includes providing a safe space for discussion among people who practice differently, as well as fostering an environment of religious acceptance and pluralism on the Brandeis campus.

BIG has weekly meetings divided for dialogue and activities and events planning. There will also be several larger events throughout the semester that tie in with BIG's emphasis on service, dialogue, and learning.
