In January 2002, reeling from a growing awareness of child sexual abuse within their church, a small group of Catholics gathered after Mass in the basement of a parish in Wellesley, Massachusetts to mourn and react. They began to mobilize around supporting victims of abuse, supportingnon-abusive priests, and advocating for structural change in the Catholic Church so that abuse would no longer occur. Voice of the Faithful (VOTF) built a movement by harnessing the faith and fury of a nation of Catholics shocked by reports of abuse and institutional complicity. Tricia Colleen Bruce offers an in-depth look at the development of Voice of the Faithful, showing their struggle to challenge Church leaders and advocate for internal change while being accepted as legitimately Catholic. Guided by the stories of individual participants, Faithful Revolution brings tolight the intense identity negotiations that accompany a challenge to one's own religion and offers a meaningful way to learn about Catholic identity, intrainstitutional social movements, and the complexity of institutional structures.
