In the history of some of the native tribes, there were people referred to as the "fire-eaters". These were people who were acknowledged by their tribes to be not only wise in mind, but people who spoke very powerfully and eloquently, and (most important), spoke truth with weight and conviction. These elders were consulted by the chief and the leaders of the tribe in the decisions. The crowd in a frenzied argument would hush and settle down immediately to listen to the "fire-eater."
He who speaks with Fire.
In light of his recent, and likely last public message, I can't think of a better epiteth for Reverend Graham. He was one who spoke truth with Fire. Will he be the last great Fire-eater?
