Warren Jeffs's official title in the FLDS Church is "President and Prophet, Seer and Revelator." He also holds the title of "President of the Priesthood." He was ordained to these positions in the Church after Rulon Jeffs, the previous Prophet and Warren Jeffs's father, died on September 8, 2002. There had been no official process for replacing Rulon as the President (Rulon had thought he would live until the Second Coming). However, Warren had been ordained as "First Counselor" to his father. Upon his father's death, he appointed himself the new leader of the church.[1] [2] One of his first statements after his father's death was directed at high ranking officials in the church: "I won't say much, but I will say this—hands off my father's wives." Then addressing the recent widows, he said, "You women will live as if father is still alive and in the next room." Within a week, Warren had married all but two of his father's several dozen wives. [3] After this, he continued to wed himself to many more women.
