The Arc of the Universe Is Long: Unitarian Universalists, Anti-Racism and the Journey from Calgary is a detailed history of the Unitarian Universalist Association's journey toward becoming an anti-racist, anti-oppressive, multicultural movement. Covering the fourteen years that begin with the passage of a racial and cultural diversity resolution at the 1992 UUA General Assembly in Calgary, Alberta, and tracing developments through General Assembly 2006 in St. Louis, Missouri, the book brings to life the voices and stories that represent a diversity of Unitarian Universalists addressing issues of race and ethnicity in our congregations and movement.

Leslie Takahashi, co-author with Leon Spencer and Chip Roush, created a discussion guide for The Arc of the Universe is Long (PDF, 55 pages). With an outline for five 90- to 120-minute sessions, the guide offers tools and prompts for a rich discussion of Unitarian Universalist history and transformation.
