The John Coltrane Church began in 1965, when Franzo and Marina King attended a performance of the John Coltrane Quartet at San Francisco's Jazz Workshop and saw a vision of the Holy Ghost as Coltrane took the bandstand. Celebrating the spirituality of the late jazz innovator and his music, the storefront church emerged during the demise of black-owned jazz clubs in San Francisco, and at a time of growing disillusionment with counter-culture spirituality following the 1978 Jonestown tragedy.

The ideology of the church was refined through alliances with the Black Panther Party, Alice Coltrane, the African Orthodox Church and the Nation of Islam. For 50 years, the church has - in the name of its patron saint, John Coltrane - effectively fought redevelopment, environmental racism, police brutality, mortgage foreclosures, religious intolerance, gender disparity and the corporatization of jazz. This critical history is the first book-length treatment of the evolution, beliefs and practices of an extraordinary African-American church and community institution.
