Salvation is deemed to require self-sacrifice in following the example and commandments of Jesus and suffering is revered. Members are encouraged to attend meetings and to speak at them. Although the church has roots in the Holiness movement and has inherited some of its features, charismatic elements are suppressed. Other standards include modest dress, not wearing jewelry, long hair for women and short hair for men, not getting piercings, not dying hair, not getting a tattoo, and avoiding activities deemed to be worldly or frivolous (such as smoking, drinking alcohol, watching television, and viewing motion pictures). Standards and practices vary geographically: for example, in some areas fermented wine is used in Sunday meetings, in other areas grape juice is used; in some areas people who have divorced and remarried are not allowed to participate in meetings, in others they may. The use of television, social media sites and other mass media is discouraged in some areas, based on the stance of the local workers and overseers. Some external standards in dress and conduct have been loosened in recent years in response to criticisms.
