Pecple who have not found spiritual satisfaction within the traditional churches may join a sect such as the Jehovah's Witnesses, the*Christian Scientists, the Mormons or the Seventh-Day Adventists. Others join a charismatic church, such as the Pentecostal Church, where emotions are freely expressed and spiritual healing is practised. In the US there are over 10 million Pentecostalists. Smaller churches in the US include the Shakers, the*Amish, the*Mennonites and the*Hutterites. America also has strong religious groups that are not churches, for example the*Promise Keepers.
