Émile Durkheim provided this classic definition in his work 'The Elementary Forms of Religious Life'. He argued that religion is not just about the supernatural, but about the social function of separating the 'sacred' from the 'profane'. By focusing on the collective nature of religious practice, Durkheim emphasized how religion reinforces social solidarity and shared identity within a community.

Samuel Huntington introduced the 'clash of civilizations' thesis in his 1993 essay and subsequent book. He argued that in the post-Cold War world, the primary source of conflict would be cultural and religious identity rather than ideological or economic differences. This perspective has been highly influential in political science and international relations, though it remains a subject of significant academic debate regarding its predictive accuracy and cultural essentialism.

Secularization is the sociological process through which religion's authority and influence decline in public life, government, and individual consciousness. As societies modernize, religious institutions often lose their traditional role as the primary source of moral guidance and social organization, shifting toward more rational or scientific explanations for worldly phenomena.

In sociology, a sect is typically defined as a smaller, breakaway religious group that maintains a high degree of tension with the surrounding society. Key characteristics include voluntary membership, where individuals choose to join based on personal conviction, and a strong emphasis on emotional commitment or 'conversion' experiences. Unlike established churches, sects often demand strict adherence to their doctrines and foster a close-knit community among members, often led by charismatic figures.

The Bible is the central religious text of Christianity, consisting of the Old Testament and the New Testament. It serves as the foundational source of doctrine, history, and moral guidance for Christians worldwide. Sociologically, the study of sacred texts is important for understanding how religious institutions shape the beliefs, values, and social behaviors of their followers within a given culture.

An ecclesia is a religious organization that is integrated into the dominant culture and claims the membership of everyone in a society. It often functions as a state religion, exerting significant influence over the social and political life of its members, effectively claiming total spiritual authority.

Islam was founded in the 7th century CE, making it the youngest of the major world religions listed. Hinduism is considered one of the oldest, while Judaism and Christianity predate Islam by several centuries. This historical timeline is widely accepted in the study of world religions.

The shift from civil religion—which refers to the quasi-religious values that bind a nation together—to common religion suggests that while formal religious authority and institutional participation may decline, religious themes continue to permeate everyday life. This implies that religious values are embedded in the 'common sense' and cultural fabric of society, influencing individual behavior and social norms even in a secularized context.

Religion has historically acted as a powerful catalyst for social change. By providing moral frameworks, mobilizing communities, and challenging existing power structures, religious movements have frequently initiated significant shifts in societal norms, political landscapes, and cultural values throughout human history.

The Pentateuch, or the Torah, consists of the first five books of the Bible: Genesis, Exodus, Leviticus, Numbers, and Deuteronomy. Since all the options listed (Deuteronomy, Leviticus, Genesis, Numbers, and Exodus) are part of this collection, 'All of above' is the correct answer.
