The following is a simple design example, but it should be emphasized that such extremely exclusive belief systems often bring negative effects, are not conducive to personal growth and social harmony, and are only for example analysis, and real practice is not advocated: **Faith Name**: Pure Realm Faith **Core Doctrine**: 1. There are two forces in the world, purity and pollution. The power of purity comes from the sacred source we believe in, while the outside world is full of "pollution" brought by various non-believers. 2. Members must always be vigilant and stay away from non-believers. Any contact with non-believers may cause themselves to be "polluted by the outside world" and thus deviate from the sacred way. 3. Keep your heart pure, stick to your faith, and resist external erosion through constant meditation, following specific rituals and studying doctrines. **Guidelines and Norms**: 1. In daily communication, members should remind each other to avoid eye contact, verbal communication or physical contact with non-believers. 2. When members find non-believers approaching in public places such as shopping malls and streets, they should move away as soon as possible and choose different routes or places. 3. If it is impossible to completely avoid being in the same space with non-believers at work or in life, members should minimize interaction and maintain an indifferent and isolated attitude. 4. Members are not allowed to join social groups or clubs of non-believers or participate in activities organized by non-believers. 5. Members who violate the rules of avoiding contact with non-believers will be given warnings, fasting, and self-reflection, depending on the severity of the case, to encourage them to adhere to the doctrine again. Such a belief system can easily lead members to close themselves off, generate prejudice and discrimination, which is not conducive to normal communication and integration with other groups in society, and may cause social conflicts and divisions. It is not desirable in reality.
