The Rev. Will D. Campbell, a renegade preacher and author who joined the civil rights struggle in the 1950s, quit organized religion and fought injustice with nonviolent protests and a storyteller’s arsenal of autobiographical tales and fictional histories, died on Monday night in Nashville. He was 88.

A family friend, John Egerton, confirmed the death. He said Mr. Campbell had moved to a nursing home in Nashville from his family farm near Mount Juliet, Tenn., after a stroke in 2011.

Mr. Campbell, one of the few white clerics with an extensive field record as a civil rights activist, wrote a score of books that explored the human costs of racism and the contradictions of Christian life in the segregated South, notably in a memoir, “Brother to a Dragonfly” (1977), a National Book Award finalist.

A knot of contradictions himself, he was a civil rights advocate who drank whiskey with Klansmen, a writer who layered fact and fiction, and a preacher without a church who presided at weddings, baptisms and funerals in homes, hospitals and graveyards for a flock of like-minded rebels that included Johnny Cash, Willie Nelson, Dick Gregory, Jules Feiffer and Studs Terkel.
