From the late 30s to the late 50s, my father, Charles Templeton, (known then as Chuck Templeton) was one of the best known evangelists in North America. He and his best friend Billy Graham toured the USA, Canada and the World preaching about Jesus.
However, today if you’ve heard of Charles Templeton’s religious career, it is because in the late ’50s he gave up his faith, and for the rest of his life, until his death in 2001, he was an agnostic. His last book was entitled Farewell to God.
