"On Faith" panelist Pamela K. Taylor is co-founder of Muslims for Progressive Values and director of the Islamic Writers Alliance. She is a member of the national board of advisors to the Network of Spiritual Progressives, and served as co-chair of the Progressive Muslim Union for two years. Taylor is a strong supporter of the woman imam movement, which seeks the full participation of Muslim women in every aspect of life, including the pulpit. In July 2005, she became the first woman in centuries to officiate Friday prayers in a mosque when the United Muslim Association of Toronto and the Muslim Canadian Congress invited her to serve as guest imam. (This event followed a number of services, sermons and prayer sessions led by women held in private venues because no mosque agreed to host them.) In February 2006, when the former Grand Mufti of Marseilles visited Toronto, he requested that Taylor lead him in congregational prayer as an unequivocal demonstration of his support for female imams. Taylor has also been active in interfaith dialogue for 20 years, both in local initiatives and speaking at numerous conferences, universities, and churches. She received her MTS from Harvard Divinity School, and writes regularly on spiritual matters and the Islamic faith. She has essays in Nurturing Child and Adolescent Spirituality: Perspectives from the World's Religious Traditions (2006) and the forthcoming The Veil: Women Writers on Its History, Lore, and Politics (2007). She has written hundreds of articles and opinion pieces for newspapers, magazines, and journals, and is an award winning poet.
