Donna Freitas is Assistant Professor of Religion at Boston University. The "On Faith" panelist's literary and academic focus is the struggle of belonging and alienation with regard to faith, particularly among young adults, and especially young women. Freitas asks the 'Big Questions' (Why are we here anyway?) and delights in discovering the many forums in which to dabble with faith, religion, spirituality, and gender. A Catholic, she also is an ardent feminist. Her books include Becoming a Goddess of Inner Poise: Spirituality for the Bridget Jones in All of Us, (2005) and Save the Date: A Spirituality of Dating, Love, Dinner & the Divine. Freitas' most recent book project is Sex and the Soul, set for publication in 2007. It is based on a national study about the influence of sexuality and romantic relationships on the spiritual identities of America 's college students. Freitas' first novel, The Possibilities of Sainthood, which is about 15-year Antonia Lucia Labella, who aspires to become the first official living saint in Catholic history, is due for publication in 2008. Freitas can be reached through her website at www.donnafreitas.com.

The Reverend William McD. Tully has been rector of St. Bartholomew's Episcopal Church in New York City since September 1994. The first professional calling of the “On Faith” panelist was to journalism, and he worked as a copy boy and local reporter at the Los Angeles Times. As a community worker for the Model Cities program at the Columbia University Graduate School of Journalism, Tully discerned an "underlying call" that turned him toward ordained ministry and study at the General Theological Seminary. After ordination in 1974, he served as curate at the Church of the Epiphany, Manhattan; associate rector at St. Francis Church, Potomac, Maryland; and then as rector of St. Columba's Church, Washington, D.C. The people and mission of St. Columba's taught Tully about church growth, Christian hospitality and hope for the future of the church. Working with a dedicated group of leaders, an enlarged clergy and professional staff at St. Bart’s, Tully has led the church in its growth and renewal. He loves his ministry and is always eager to meet and work with others who have found a home and a ministry at St. Bart's.

Rabbi David Saperstein is the Washington representative of Judaism's Reform Movement as Director of the Religious Action Center of Reform Judaism, a position he has held for 30 years. The "On Faith" panelist also co-chairs the Coalition to Preserve Religious Liberty, and serves on the boards of numerous national organizations including the NAACP and People For the American Way. In 1999, Saperstein was elected first chair of the U.S. Commission on International Religious Freedom created by Congress. The Religious Action Center advocates for a broad range of social justice issues and provides extensive legislative and program materials for synagogues, federations and Jewish community relations councils nationwide. It also coordinates social action education programs that train nearly 3,000 Jewish adults, youth, rabbinic and lay leaders each year. Also an attorney, Saperstein teaches seminars in First Amendment Church-State Law and in Jewish Law at Georgetown University Law School. He co-authored Jewish Dimensions of Social Justice: Tough Moral Choices of Our Time (1998).

"On Faith" panelist James Anderson is a retired Episcopal priest, an almost full-time volunteer in the community, a part-time farm manager, and independent writer. Anderson was one of four founders of the Alban Institute in Washington, D.C., and served as first president of its board. The Institute has grown to become one of the most respected sources of help in the nation to local congregations. Anderson is the author or co-author of three books on ministry in the local church: To Come Alive (1973) and The Management of Ministry (1978), co-authored with Ezra Earl Jones, have been widely used in the training and education of clergy. Anderson, who has wide experience as an advisor and consultant to a variety of religious organizations, also served as assistant to the Bishop for Congregational Development for the Episcopal Diocese of Washington and director of Field Studies for the Cathedral College of the Laity at the Washington National Cathedral. He's currently writing a book with Bishop Jane Holmes Dixon examining the 40-year history of the effort to fully integrate women into the ordained ministry of the Episcopal Church.
