Religion encompasses a wide range of practices, ideas and beliefs. It often includes devotion to a supreme being or deity, as well as moral codes, and belief in life after death. It may also involve rituals and ceremonies, sacred books, a divine hierarchy or clergy, places of worship, and symbols and days that are considered holy. Most religions, if not all, have some form of salvation. This can be either in a literal sense, such as going to heaven, or more in a symbolic sense, such as achieving nirvana.
Regardless of its nature, most religions have some form of community, and many people feel the need to belong to a group of like-minded people. This need is sometimes identified as a contributing factor to mental health problems, such as anxiety and depression. In addition, it is a key element in social support, which has been shown to improve health outcomes and decrease risky behaviors, such as drug and alcohol use.
A major trend in the modern world is the resurgence of religiosity, particularly among young people. This has led to a rise in new religions and the expansion of existing ones. In the United States, for example, Islam has become a significant presence, and there has been a rapid increase in evangelical Christianity.
Scholars have a variety of approaches to the study of religion. Some scholars, including Emile Durkheim, have argued that religion is simply a set of beliefs and practices that generates solidarity and binds people together. Others have used a functional approach, such as that of Paul Tillich, who defined it as whatever dominant concerns organize one’s values, whether or not they include belief in supernatural realities.
Many scholars are now turning to a critical analysis of the concept of religion. Those in this “reflexive turn” are criticizing the concept’s modern semantic expansion, and its history of being used to judge other cultures as godless and backward. They are also questioning its validity as a taxon for human activities and arguing that the idea of a prototypical religion is based on European colonialism.
Some have used the arguments of the critics to develop polythetic definitions of religion, which avoid claiming that an evolving social taxon has an ahistorical essence. However, it is not clear that these polythetic approaches are any less ethnocentric than the monothetic definitions they reject. In any case, the debate about how to define religion is a useful exercise because it helps bring attention to the fact that religion is an important part of the lives of two-thirds of Americans. It is therefore important for government to respect that role, and that Presidents and Senators should appoint judges who are sensitive to the importance of religion in public life. To do otherwise would be to erode the foundation of our democracy.
