Final answer:
An ethnic religion is limited to a group with a common heritage and is characterized by adherence to cultural traditions and practices tied to a specific geographical area. These religions shape society's views on various aspects of life and often remain within the distinct community rather than spreading universally.
Step-by-step explanation:
A religion which is limited to a group with a common heritage is often referred to as an ethnic religion. These religions have a concentrated spatial distribution and their principles are closely related to the physical characteristics of the location where their adherents live. Unlike universalizing religions, which seek followers across different cultures and locations, an ethnic religion is usually practiced by a specific group of people who share common aspects of culture, heritage, or language.
Furthermore, some religions form around the idea of totemism, where a divine connection is believed to exist between humans and other natural beings, reinforcing the geographical and cultural specificity of a religion. Another relevant term is sect, which refers to a small group that has branched off from a larger religious denomination, sometimes forming established sects or smaller, tightly knit religious communities.
Overall, such religions deeply influence every aspect of the society of their adherents, including politics, economics, and their interactions with the natural environment, further emphasizing their particular characteristics and the shared identity of the community.
