The phrase "religious economy" refers to religious persons and organizations interacting within a market framework of competing groups and ideologies. An economy makes it possible for religious suppliers to meet the demands of different religious consumers.Wortham, Robert A. Religious Choices and Preferences: North Carolina's Baskin Robbins Effect? 2004. 27 Sep. 2007. By offering an array of religions and religious products, a competitive religious economy stimulates such activity in a market-type setting.

The theory of religious economy applies rational choice theory to the theory of religion such that supply and demand are used to model the development and success of organized religions. Major proponents of the theory include William Sims Bainbridge, Roger Finke, Laurence Iannaccone, and Rodney Stark.

Defining a religious economy Various definitions of a "religious economy" exist: Sociologically, a religious economy includes "all of the religious activity going on in any society". A economic view may emphasise the "environment where religious goods and services are exchanged between consumers [...] and producers [...]". A marketing approach to the religious economy may focus on markets or marketplaces for conversions or for physical religious products.

Major debates The idea of religious economy frames religion as a product and as those who practice or identify with any particular religion as a consumer. But when the idea of belief is brought into the equation, this definition expands, and ideology affects the "product" and who "consumes" it. When examining depictions of religious identity in a global world, it is easy to see how ideology affects religious economy.

Carl L. Bankston III refers to religions and religious groups as "…competing firms [that vie for] customers who make rational choices among available products…" (311). Using a liberal economic (see Economic liberalism) framework for analysis, Bankston is claiming that religions and religious groups’ popularity is dependent on the laws of supply and demand. As a marketplace, religious consumers are subject to things such as marketing, availability of product, resources, brand recognition, etc. But unlike some actual commodity such as a computer, these commodities speak to an individual's beliefs. Bankston poses the idea that belief deals with ideology and extends beyond what one would typically define as a market good by stating "…belief is produced and resides in communicated thoughts, (and) the consumers of goods of faith can only become consumers by becoming producers, by participating in interactions of belief…" (322).

Secularization and religious economy

Prior to the emergence of the theory of religious economy some scholars of religion, such as Steve Bruce, believed that modernization would inevitably lead to the erosion of religiosity. These sociologists have predicted the disappearance of religion from Earth, based on the decline in religious belief and observance in Western Europe. According to the theory of religious economy, societies that restrict supply of religion, either through an imposed state religious monopoly or through state-sponsored secularization, are the main causes of drops in religiosity. Correspondingly, the more religions a society has, the more likely the population is to be religious. This is refuted in the orthodox view by stating that if a liberal religious community is tolerant of a wide array of belief, then they are less likely to hold certain beliefs in common, so nothing can be shared and reified in a community context. If nothing is shared, then nothing is shunned, and there is thus a loss in observance of modern liberal traditions.

Revival According to Rodney Stark, revival is another aspect of religious change which coincides with secularization. Revival often begins in a context of perceived spiritual or moral decline, where individuals or communities feel alienated from their faith or see institutional religion as stagnant or corrupt. External factors, such as social upheaval, economic challenges, or cultural shift can also contribute to this dissatisfaction.

This can lead to a growing awareness of the need for renewal among followers of the faith. Individuals may experience a sense of guilt or conviction, often fuelled by charismatic leaders or preachers emphasizing the urgency of repentance. Consequently, many followers go through personal transformations, or "conversions", where individuals recommit to their faith, often adopting stricter moral and spiritual practices.

These revivals can spread rapidly through social networks, media, or preachers, gaining momentum as more people join the movement. Over time, these revivals either institutionalize, becoming part of the religious tradition, or lose momentum as the initial movement wanes. In some instances, the movements can also lead to the establishment of new denominations, sects, or other organizations.

Some notable examples of revivals include The Great Awakenings, The Pentecostal Revival, and movements such as the 18-century Wahhabi revival.

Sects Over time, established religious groups will spawn smaller and less worldly subgroups, or "schisms", of the faith, knows as sects. According to Troeltsch, due to the nature of these sects, they are often short-lived, and do not flourish into a full religion or denomination. Some notable exceptions to short sect lifespans include Jehovah's Witnesses and the Amish.

Despite their usual short life-span, according to Stark and Bainbridge, instead of dying out, some sects can evolve into larger denominations of their parent faith. This process usually requires that a sect realigns its beliefs to be more world-accommodating, grows in size, and forms a more rigid internal hierarchy, as opposed to having a single charismatic leader. This process can come as a result of multiple factors, such as:

A generational shift, where younger generations within the sect may seek more comfort and integration within society. A social mobility shift, where some members of the sect may achieve upward mobility and become more prosperous, consequently adopting more mainstream norms and values. Newer members joining the sect and growing its size may break down the close-knit communities within the sect, leading to further institutionalization.

As these sects evolve into full-fledged denominations, they start to offer competitive alternatives to their parent faiths. This produces a shift, where religious groups within a population will follow these new subgroups instead of the parent faith, working against the demise of religion. This trend of revival provides a plausible explanation as to why religious groups may persist despite predictions of their decline, and why once-prominent religious organisations have dissipated.

Cults Unlike a sect, which seeks to reform or revive traditions from its parent religion, a cult often introduces novel religious ideas or practices. Sociologists sometimes use "cult" as a neutral term for a new religious movement (NRM), and historically, all major religions can be considered cults at their inception. However, the modern stigma attached to the term "cult" has fuelled hostility between these movements and their surrounding societies. Rodney Stark identifies cult formation as a primary response to secularization.

Cult formation can occur as a result of multiple factors. As old faiths weaken, cults may emerge to fill the "spiritual void" left behind. Cults may also emerge as a response to rapid societal transformation, such as industrialization, globalization, or technological advancements. These changes can create uncertainty and alienation, where cults can provide a sense of meaning, belonging, and stability in such times.

Cults are often differentiated by the fact that they may not have formed as a schism of a larger religion, and that they often introduce new ideas and beliefs not previously seen. They are able to cater to specific groups, such as the marginalized, or seekers of mystical experiences. This allows cults to appeal to these groups in a way that traditional religion may not be able to.

Stark argues that this allows religion to undergo a transformation of expression, allowing it to adapt quickly to a changing social environment, and remain relevant in societies where traditional religion no longer fits.

Strict regulations to enforce strong ties Strict churches are prevalent in the US and around the world, and they are characterized by strong ties within the group with few weak ties branching outside to other groups. Strict churches arise from strict doctrines and can be in many forms such as large churches, sects, or cults but are not limited to these. Churches are most often known for their “cosmopolitan networks, while sects tend to consist of intense local networks,”Rodney Stark, 2007. Sociology. Tenth Edition. Thomas Wadsworth. ./ while this may be true for “unstrict” doctrines this is not always the case for strict doctrines. Strong doctrines can arise from certain sects as various religions have done such as Orthodox Judaism, Islam, certain denominations of Christianity, or can include rather smaller cults or small sects. What all strong doctrines employ though, are formal controls to discourage free riding within the group and to keep the church strong and together.Hechter, Michael. Principles of Group Solidarity. University of California Press. These controls can vary from church to church but all serve the same purpose of keeping group solidarity.

As commonly seen strict churches employ various means of keeping their ties in their church strong while limiting excessive access to other groups such as dress code, eating habits, and rituals that prevent mixing with other groups. The implication of these, “strict demands ‘strengthen’ a church in three ways; they raise overall levels of commitment, they increase average rates of participation, and they enhance the net benefits of membership.”Laurence R. Iannaccone, 1994. "Why Strict Churches Are Strong," American Journal of Sociology, 99(5), pp. 1180-1211. Complying with these demands prevent the members of a church from free loading within the group and promote group solidarity. The strict rules that govern and regulate a church actually help and promote the strength of the ties within the group. Those who don't comply with these strictures are screened out leaving only those who do comply and comply earnestly.” These strict doctrines and regulations serve to keep the church strong and together while screening out members that may actually harm the church unintentionally by being free loaders within the group.

Church-sect theory

Originally proposed by H. Richard Niebuhr in his book The Social Sources of Denominationalism, the theory discusses the difference between churches and sects. Niebuhr proposed that there is a cycle which sects and churches follow. Religions originate as sects designed to serve the needs of the deprived. If they flourish, they increasingly serve the interests of the middle and upper classes and are transformed into churches. Once the sects have become churches they become less effective in satisfying the needs of the lower class and the formation of a sect is re-created.

In 1963 Benton Johnson revised the church-sect theory into its current state. Church and sect form opposite poles on an axis representing the amount of "tension" between religious organizations and their social environments. Tension, as defined by Benton Johnson, is "a manifestation of deviance." The tension is described to be between the group's members and the outside world. Churches are described as religious bodies having low tension, whereas, sects have high tension.
