There is some amount of overlap between subcategories of religious studies and the discipline itself. Religious studies seeks to study religious phenomena as a whole, rather than be limited to the approaches of its subcategories.
Anthropology of religion The
anthropology of religion is principally concerned with the common basic human needs that religion fulfills. The
cultural anthropology of religion is principally concerned with the cultural aspects of religion. Of primary concern to the cultural anthropologist of religions are rituals, beliefs, religious art, and practices of piety.
Economics of religion Gallup surveys have found that the world's poorest countries may be the most religious. Of those countries with average per-capita incomes under $2000, 95% reported that religion played an important role in their daily lives. This is contrasted by the average of 47% from the richest countries, with incomes over $25,000 (with the United States breaking the trend by reporting at 65%). Social scientists have suggested that religion plays a functional role (helping people cope) in poorer nations.
History of religion The history of religions is not concerned with theological claims apart from their historical significance. Some topics of this discipline are the
historicity of religious figures, events, and the evolution of doctrinal matters.
Interreligious studies Interreligious studies is an emerging academic field that is focused on interactions among religious groups, including but not limited to
interfaith dialogue. Journals and interdisiplinary organizing efforts grew especially in the 2010s. A pivotal anthology for the field is
Interreligious/interfaith studies: Defining a new field by
Eboo Patel,
Jennifer Howe Peace, and Noah Silverman.
Literary approaches There are many approaches to the study of sacred texts. One of these approaches is to interpret the text as a literary object. Metaphor, thematic elements, and the nature and motivations of the characters are of interest in this approach. An example of this approach is
God: A Biography, by
Jack Miles.
Neurological approaches The
temporal lobe has been of interest and has even been termed the "God center" of the brain. (Ramachandran, ch. 9)
Neurological findings in regard to religious experience is not a widely accepted discipline within religious studies. Scientific investigators have used a
SPECTscanner to analyze the brain activity of both Christian contemplatives and Buddhist meditators, finding them to be quite similar.
Origin of religion The "origin of religion" refers to the emergence of religious behavior in
prehistory, before written records.
Psychology of religion The psychology of religion is concerned with the psychological principles operative in religious communities and practitioners.
William James's
The Varieties of Religious Experience analyzed personal experience as contrasted with the social phenomenon of religion. Some issues of concern to the psychologist of religions are the psychological nature of
religious conversion, the making of religious decisions,
religion and happiness, and the psychological factors in evaluating religious claims.
Sigmund Freud was another figure in the field of psychology and religion. He used his psychoanalytic theory to explain religious beliefs, practices, and rituals, in order to justify the role of religion in the development of human culture.
Sociology of religion The sociology of religion concerns the
dialectical relationship between religion and
society; the practices, historical backgrounds, developments, universal themes and roles of religion in society. There is particular emphasis on the recurring role of religion in all societies and throughout recorded history. The sociology of religion is distinguished from the philosophy of religion in that it does not set out to assess the validity of religious beliefs, though the process of comparing multiple conflicting
dogmas may require what
Peter L. Berger has described as inherent "methodological atheism". Whereas the sociology of religion broadly differs from theology in assuming the invalidity of the supernatural, theorists tend to acknowledge socio-cultural
reification of religious practise. The sociology of religion also deals with how religion impacts society regarding the positive and negatives of what happens when religion is mixed with society. Theorist such as Marx states that "religion is the opium of the people" - the idea that religion has become a way for people to deal with their problems. At least one comprehensive study refutes this idea. Research has found that secular democracies like
France or
Scandinavia outperform more theistic democracies on various measures of societal health. The authors explains, "Pressing questions include the reasons, whether theistic or non-theistic, that the exceptionally wealthy U.S. is so inefficient that it is experiencing a much higher degree of societal distress than are less religious, less wealthy prosperous democracies. Conversely, how do the latter achieve superior societal health while having little in the way of the religious values or institutions?"
Law and religion Vogel reports that in the 1970s a new "law and religion" approach has progressively built its own contribution to religious studies. Over a dozen scholarly organizations and committees were formed by 1983, and a scholarly quarterly, the
Journal of Law and Religion first published that year and the
Ecclesiastical Law Journal opened in 1999. Many departments and centers have been created around the world during the last decades. As of 2012, major Law and Religion organizations in the U.S. included 500 law professors, 450 political scientists, and specialists in numerous other fields such as history and religious studies. Between 1985 and 2010, the field saw the publication of some 750 books and 5000 scholarly articles. Scholars are not only focused on strictly legal issues about religious freedom or non establishment but also on the study of religions as they are qualified through judicial discourses or legal understanding on religious phenomena. Exponents look at canon law, natural law, and state law, often in comparative perspective. Specialists have explored themes in western history regarding Christianity and justice and mercy, rule and equity, discipline and love. Common topics on interest include marriage and the family, and human rights. Moving beyond Christianity, scholars have looked at law and religion interrelations in law and religion in the Muslim Middle East, and pagan Rome.
Religion and cinema The earliest serious writing on the interface between religion and cinema appeared in the work of film critics like
Jean Epstein in the 1920s. The subject has grown in popularity with students and is cited as having particular relevance given the pervasiveness of film in modern culture. Approaches to the study of religion and film differ among scholars; functionalist approaches for instance view film as a site in which religion is manifested, while theological approaches examine film as a reflection of God's presence in all things. ==Methodologies==
