Kenneth Copeland learned at the feet of prosperity gospel founders Kenneth Hagin and Oral Roberts. Copeland calls Roberts, who believed that God had anointed his right hand with healing power, his "spiritual father."
The Copelands have since created their own unique brand of theology, emphasizing that the spoken word -- a Word of Faith -- can turn prayers into reality. Kenneth Copeland teaches that simply uttering the words "I'm sick" can lead to illness, and that proclaiming yourself well can likewise lead to health.
"Our health, our wealth and our place in eternity is in our mouths. Everything about us has been, and will be, determined by the words we speak," Copeland has said.
Arden said that church members were taught to repeat certain Bible passages, almost like a magic spell, to ward off disease.
"There were healing Scriptures we had to recite over and over again, and eventually, whatever you say will come to pass."
The Copelands don't claim to be healers, though they teach that believers who sow "seeds of faith" -- sometimes through donations -- can see miraculous results.
One account on the ministry’s website says that a Dutch boy was cured of autism after his mother attended Gloria Copeland's healing school and watched Eagle Mountain church services online.
Arden recalled donating $400 -- all she had in her savings account at the time -- to the church when her daughter had a serious ear malady.
"I was a broke, single mother earning $7.50 an hour, so that was a fortune to me."
Her daughter required four surgeries before she was healed, Arden said.
Now a financial analyst in New York City, Arden said she keeps her distance from organized religion, but understands what draws certain kinds of Christians to churches like Eagle Mountain.
"About 90 percent of the people were just like me," she said. "They needed hope, and they needed to believe that there was something bigger than themselves that would guide and protect them and keep the whole crush of life from pressing down on them."
