When Theresa Bixby, 63, learned that she had breast cancer four years ago, she reacted as many Americans do. "One of my first thoughts was, 'will they pay?' " she said. But she wasn't talking about a conventional insurance plan. She lost hers when she left her full-time position for part-time work at her church in Greenville, S.C. She was worried about the program that she had joined six months earlier: Christian Healthcare Ministries. Christian Healthcare Ministries is not an insurance company. It is a nonprofit "health care sharing ministry" based in Barberton, Ohio.
