George A. Smith refers to Black Pete Kerr as a "revelator".
George A. Smith, "Historical Discourse," Deseret News, December 12, 1864, 90
There was at this time in Kirtland a society that had undertaken to have a community of property, it has sometimes been denominated the Morley family, as there was a number of them located on a farm owned by Captain Isaac Morley. These persons had been baptized but had not yet been instructed in relation to their duties. A false spirit entered into them, developing their singular extravagant and wild ideas. They had a meeting at the farm, and among them was a negro known generally as Black Pete who became a revelator. Others also manifested wonderful developments; they could see angels, and letters would come down from heaven, they said, and they would be put through wonderful unnatural distortions. Finally on one occasion, Black Pete got sight of one of those revelations carried by a black angel, he started after it, and ran off a steep wash bank 25 feet high, passed through a tree top into the Chagrin river beneath. He came out with a few scratches, and his ardor somewhat cooled.
