I remain profoundly convinced that practical multifaith projects are the single best vehicles for Jews, Christians, and Muslims to form the bonds that can build an American faith-based coalition of moderates. Muslims need to incorporate the reality of our theological, historical, and experiential connections to Christians and Jews into our lives and religious practice.
If you attend a mosque, speak to the imam about creating common projects with a local Christian and/or Jewish congregation. They are, after all, fellow People of the Book. You could suggest reading Scriptures together, or exploring common history, or comparing attitudes toward social justice. You could suggest inviting them to break the fast with you one Ramadan evening. If you are Jewish or Christian, invite your Muslim neighbors to join you on Yom Kippur to break the fast or to celebrate communion.
