IrreligionIrreligion is the neglect or active rejection of religion and, depending on the definition, a simple absence of religion. Irreligion takes many forms, ranging from the casual and unaware to full-fledged philosophies such as atheism and agnosticism, secular humanism and antitheism. Social scientists tend to define irreligion as a purely naturalist worldview that excludes a belief in anything supernatural. The broadest and loosest definition, serving as an upper limit, is the lack of religious identification, though many non-identifiers express metaphysical and even religious beliefs.
World religionsWorld religions is a category used in the study of religion to demarcate the four—and in some cases more—largest and most internationally widespread religious movements. Christianity, Islam, Hinduism and Buddhism are always included in the list, being known as the "Big Four". Some scholars also include other world religions, such as Judaism, Sikhism, Taoism, the Baháʼí Faith, Jainism, Confucianism, Shinto and Zoroastrianism, in the category.
HolidayA holiday is a day or other period of time set aside for festivals or recreation. Public holidays are set by public authorities and vary by state or region. Religious holidays are set by religious organisations for their members and are often also observed as public holidays in religious majority countries. Some religious holidays, such as Christmas, have become or are becoming secularised by part or all of those who observe them. In addition to secularisation, many holidays have become commercialised due to the growth of industry.
Nontheistic religionNontheistic religions (not to be confused with atheism) are traditions of thought within a religious context—some otherwise aligned with theism, others not—in which nontheism informs religious beliefs or practices. Nontheism has been applied and plays significant roles in Hinduism, Buddhism, and Jainism. While many approaches to religion exclude nontheism by definition, some inclusive definitions of religion show how religious practice and belief do not depend on the presence of a god or gods.
SecularitySecularity, also the secular or secularness (from Latin saeculum, "worldly" or "of a generation"), is the state of being unrelated or neutral in regards to religion. Origins of secularity can be traced to the Bible itself and fleshed out through Christian history into the modern era. In the medieval period there were even secular clergy. Furthermore, secular and religious entities were not separated in the medieval period, but coexisted and interacted naturally.
Ethnoreligious groupAn ethnoreligious group (or an ethno-religious group) is a grouping of people who are unified by a common religious and ethnic background. Furthermore, the term ethno-religious group, along with ethno-regional and ethno-linguistic groups, is a sub-category of ethnicity and is used as evidence of belief in a common culture and ancestry. In a narrower sense, they refer to groups whose religious and ethnic traditions are historically linked.
Religious textReligious texts, including scripture, are texts which various religions consider to be of central importance to their religious tradition. They differ from literature by being a compilation or discussion of beliefs, ritual practices, moral commandments or laws, ethical conduct, spiritual aspirations, and for creating or fostering a religious community. Within each religion, these sacred texts are revered as authoritative sources of guidance, wisdom, and divine revelation.
Religious skepticismReligious skepticism is a type of skepticism relating to religion. Religious skeptics question religious authority and are not necessarily anti-religious but skeptical of specific or all religious beliefs and/or practices. Socrates was one of the most prominent and first religious skeptics of whom there are records; he questioned the legitimacy of the beliefs of his time in the existence of the Greek gods.
TenrikyoTenrikyo is a Japanese new religion which is neither strictly monotheistic nor pantheistic, originating from the teachings of a 19th-century woman named Nakayama Miki, known to her followers as "Oyasama". Followers of Tenrikyo believe that God of Origin, God in Truth, known by several names including "Tsukihi," "Tenri-Ō-no-Mikoto" and "Oyagamisama (God the Parent)" revealed divine intent through Miki Nakayama as the Shrine of God and to a lesser extent the roles of the Honseki Izo Iburi and other leaders.
Indigenous religionIndigenous religions is a category used in the study of religion to demarcate the religious belief systems of communities described as being "indigenous". This category is often juxtaposed against others such as the "world religions" and "new religious movements". The term is commonly applied to a range of different belief systems across the Americas, Australasia, Asia, Africa, and Northern Europe, particularly to those practiced by communities living under the impact of colonialism.
