All societies have beliefs and practices that help them understand supernatural and spiritual phenomena. Religion takes different forms in the many types of societies that have existed, but ultimately it seeks to make sense out of life, death, and the other mysteries of human existence.
The world’s major religions today include Christianity, Islam, Hinduism, Buddhism, Confucianism, and Judaism. They differ in many respects, including the nature of their belief in God, whether their religion began with the efforts of one particular individual, and whether a sacred text is involved.
Religion serves several functions for society. It gives meaning and purpose to life, reinforces social stability and social control, and promotes physical and psychological well-being. Yet religion can also perpetuate social inequality and promote social conflict among peoples with different religious faiths. Traditionally religion has also reinforced gender inequality. Symbolic interactionism explores the micro side of religion and focuses on the role religion plays in our daily lives and the ways in which we interpret religious experiences.
The primary types of religious organization include the church (either an ecclesia or a denomination), sect, and cult. These types differ in many ways, including their size and integration into society. Cults have a very negative image, but Christianity, Judaism, and various denominations all began as cults.
The United States is, according to many measures, one of the most religious societies in the industrial world. Most people believe in God, and a strong majority belong to a church or synagogue. Religious affiliation is related to several demographic variables in which sociologists are interested, including social class and race. Liberal Protestants and Jews tend to be relatively wealthy and well educated, while Conservative Protestants tend to be poorer and less educated. Catholics and Moderate Protestants tend to occupy a middle ground on these variables.
Religiosity is a multidimensional concept that gets beyond actual membership in a church or synagogue. The more religious people are, the more conservative they tend to be on various social and moral issues.
Two religious trends in recent decades in the United States include secularization and the rise of religious conservatism. Despite fears that the United States is becoming a less religious society, the best evidence indicates that religion continues to play an important role in the lives of individuals and their families. The rise of religious conservatism has an important and controversial impact on national political affairs.
Religion seems to have at least two important effects on the lives of individuals. Higher levels of religiosity are associated with reduced involvement in deviant behavior and with greater physical and psychological well-being.
