 Yet by the end of the 19th century, Adventists generally agreed the Spirit is a personal being, and part of the Trinity.Ellen White was influential in bringing about an understanding of the Holy Spirit and spoke of "the Third Person of the Godhead" repeatedly and "a divine person".Some Adventist books include Le Roy Froom, "The Coming of the Comforter" (1928); W. H. Branson, "The Holy Spirit" (1933); G. B. Thompson, "The Ministry of the Spirit" (1914); Francis M. Wilcox, "The Early and the Latter Rain" (1938).
