Smart said Mitchell held bizarre religious views, melding traditional Mormon philosophy with new ageism and his own doctrine that included a book he wrote, "The Book of Immanuel David Isaiah," which he made Smart read.
She said Mitchell forced her to pray for lengthy periods and said Mitchell would pray out loud for Smart to have sex with him.
"The things that he would say in his prayers were things that I would never have said," she said. "He would say, 'Please bless me,' [Smart], that I would be able to cope with my wifely duties and be able to rise to the occasion and fulfill my wifely duties. That is about the farthest thing from my prayers."
Mitchell also had his confessed accomplice Wanda Barzee make up a book of hymns and would make Smart sing whatever songs he chose.
She testified that Mitchell declared that he was the one destined to fight the anti-Christ because he was the "one mighty and strong" and the "Davidic King."
"Nine months of living with him and seeing him proclaim that he was God's servant and called to do God's work and everything he did to me ... is something that I know that God would not tell somebody to do," she said. "God would never tell someone to kidnap her at knifepoint from their bed, from her sister's side ... never continue to rape her and sexually abuse her."
Lawyer Robert Steele also had Smart describe Mitchell's belief in a healing process he called lymphology which involved touching places that hurt and "bouncing," which was jumping up and down. She said he was a restless sleeper who frequently got up during the night to bounce for several minutes, sometimes on one leg, before going back to bed.
In addition, Steele asked Smart if she ever saw Mitchell lose consciousness.
"Yes. We were in California at the time. He was in the middle of raping me and he experienced a seizure," she said calmly.
Mitchell, 57, is charged with kidnapping and transporting a minor across state lines for sexual purposes. He was captured in March 2003. Barzee has already confessed and has been sentenced to 15 years in prison.
She did, however, make an effort to get help when she was allowed to go to a bathroom in a Hard Rock Cafe and tried to scratch "Help" on the bathroom wall.
She also contributed to her rescue after Mitchell took them to California. She told Mitchell that God wanted them to return to Salt Lake City. She suggested he pray on it, and said he could probably kidnap another wife from a Mormon camp for girls in the area.
Mitchell supposedly prayed about her suggestion and decided to return to Salt Lake City where Smart was eventually discovered and rescued.
