One resource you might consider is our Building Bridges of Understanding: An Interfaith Response to 9/11. While a little dated in some respects, it still presents a very good basic introduction into six major religious traditions that coexist in California.
You can download a PDF of the study guide here. Print copies and a VHS tape is available from our office. We are looking into finding to revise the study guide and to reissue the DVD version of the video resources. If you want information, or can help us with this project, please let us know!
