Gail Seavey                gseavey@thefuun.org

Reverend Gail Seavey, Lead Minister

“At FUUN I am part of a shared ministry that arises from the expression of this community’s unique experiences of the holy spirit of compassion and justice during worship. I am part of a shared ministry made up of the diverse and surprising ways that spirit calls each of one of us to serve love and justice at home, at church, at work, as neighbors and as citizens.”

The congregation called the Reverend Gail S. Seavey to serve us in the fall of 2005. Having served both a humanist and a traditional Universalist congregation, the Rev. Seavey describes herself as “a theological Unitarian Universalist, believing in a sacred Unity that is expressed in diversity.” A committed social activist, the Rev Seavey has been a leader in family and sexual violence prevention, interfaith dialogue, and economic equity programs. She now serves on the Middle TN Jobs with Justice Board, the TN Advisory Committee to the U.S. Civil Rights Commission and as Executive Secretary of Nashville Organized for Action and Hope (NOAH).
