Religion is a vast and varied collection of cultural beliefs, practices, values and ethics. In many cases, there are many similarities among the various religions that exist throughout the world and they share some of the same basic components. This makes religion a difficult concept to define. Attempts at definitions have typically focused on identifying the elements that separate religion from other cultural phenomena, such as philosophy, ethics and traditions. However, it is important to recognize that these different components can also exist within one culture at a given time and place. Therefore, the resulting definition of religion must take these differences into account.
There are several theories about the origin of religion. Many scholars believe that religion arose out of human curiosity about the big questions of life and death as well as from people’s fear of uncontrollable forces. Religion provided answers to these questions and a source of hope. This hope could come in the form of a promise of eternal life, a belief in a loving creator who would watch over humans and provide for them or a conviction that life has meaning and purpose.
Most major religions believe in the existence of a supreme being or god. Most also have a set of rules that believers must follow to be in good standing with the deity. These rules generally include some combination of a code of morality, rituals and ceremonies, a sacred book or texts, and a set of holy days that are celebrated by the religion. Some of these sacred days are related to recurring natural events (the new and full moon, the two solstices) or are celebrated because they are associated with a religious figure or event.
The majority of Americans who are religiously affiliated say their religion is very important to them. These affiliations are particularly strong among Jehovah’s Witnesses, historically black Protestants, Mormons and evangelical Protestants. Despite this, there are also a number of people who describe themselves as having no religion at all or who say that they are spiritual but not religious. These “nones” have a very different view of religion than the religiously affiliated. Roughly three-in-ten of them believe that God exists and that he or she is a personal being.
Sociological perspectives on religion aim to understand the functions that religion serves, the inequality and other problems that it can reinforce and perpetuate, and the role that it plays in our daily lives. The three main sociological perspectives on religion are the conflict perspective, the symbolic interactionist perspective and the naturalistic perspective.
A fourth approach, the materialist perspective, argues that the term “religion” should be understood as a social construction and thus should be treated as such in research. This is in contrast to the views of some who claim that there is a core essence that can be identified as “religion” in all cultures. These views have been controversial in the study of religion because they do not recognize that a social construction can have multiple meanings, and because they may overlook some important cultural contexts when they try to identify that core essence.
