Another such group are the Amish, who reject many modern technological advances and severely limit contact with the outside world. The Unitarian Universalist Association, which includes both Christian and non-Christian members, is among the most open and tolerant of Protestant religious traditions. Unitarian Universalists reject the doctrine of the Trinity, seeing Christ as a great teacher, not a divine incarnation. They tend to avoid dogma as restrictive and even presumptuous, choosing to emphasize inclusiveness and understanding rather than a specific religious creed. The Christian Science movement, founded by Mary Baker Eddy, holds that the spiritual world is the true reality, compared to which the material world is an illusion.
Christian Scientists believe that sin and illness can be overcome by spiritual powers.
For this reason they tend to avoid medicines and medical procedures in favor of divine healing. Jehovah's Witnesses accept the Bible as factually true in every detail and anticipate the coming of God's kingdom after the battle of Armageddon, which is considered imminent and which is expected to be followed by a thousand-year reign of Christ on earth. The guiding accents in the Protestant experience have been the formation of communities and the power of direct experience. Two other fundamental doctrinal points set Protestant Christians apart from believers in the Roman Catholic tradition . The Bible is regarded as the only source of infallible, received truth, and the believer is justified by God's grace, obtained through his or her faith in Christ not by good deeds or the mediation of any religious institution.
