According to Latour:
  • involving no outside cause or spiritual basis; fully of this world
  • when there is no already-accepted referee when there is a conflict

From Wikipedia:
Secularity derives from the Latin root saecularis meaning "of a generation, belonging to an age" or "worldly," "temporal" .

"The Christian doctrine that God exists outside time led medieval Western culture to use secular to indicate separation from specifically religious affairs and involvement in temporal ones."

"Secularity is best understood, not as being "anti-religious", but as being "religiously neutral" since many activities in religious bodies are secular themselves and most versions of secularity do not lead to irreligiosity."

From the Online Etymology Dictionary:
from the late 13c., "living in the world, not belonging to a religious order," also "belonging to the state," from Old French seculer, from Late Latin saecularis "worldly, secular," from Latin saecularis "of an age, occurring once in an age," from saeculum "age, span of time, generation," probably originally cognate with words for "seed," from PIE root *se(i)- "to sow" (cf. Gothic mana-seþs "mankind, world," literally "seed of men").

Used in ecclesiastical writing like Greek aion "of this world" (see cosmos). It is source of French siècle. Ancient Roman ludi saeculares was a three-day, day-and-night celebration coming once in an "age" (120 years).

From a paper by Iain Benson: Notes Towards a (Re)Definition of the "Secular":
  • "Implicit in this religion free neutrality is the notion that the secular is a realm of facts distinct from the realm of faith. This understanding, however, is in error. Parse historically the word “secular” and one finds that secular means something like non-sectarian or focused on this world, not “non-faith.”"
  • "A proper understanding of secular, however, will seek to understand what faith claims are necessary for the public sphere, and a properly constituted secular government (non-sectarian not non-faith) will see as necessary the due accommodation of religiously informed beliefs from a variety of cultures."

From Wikipedia, on Luther's "On Secular Authority"
"Martin Luther's book, On Secular Authority, was an ardent expression of the principle of Liberty of Conscience. "Liberty of conscience" is the principle that forbids human authorities from coercing people's spiritual beliefs. In this book, Luther insisted that God requires voluntary religious beliefs. Compelled or coerced faith is insincere and must never be allowed. Luther insisted that "liberty of conscience" was one of Jesus Christ's principles. According to Luther, the civil government's role is simply to keep outward peace in society. The civil government has no business enforcing spiritual laws. "The laws of worldly government extend no farther than to life and property and what is external upon earth," Luther insisted."

Vs Secularism

From the Online Etymology Dictionary:
"doctrine that morality should be based on the well-being of man in the present life, without regard to religious belief or a hereafter," 1846, from secular + -ism.

From Wikipedia:
"Secularism is the principle of separation of government institutions, and the persons mandated to represent the State, from religious institutions and religious dignitaries. In one sense, secularism may assert the right to be free from religious rule and teachings, and the right to freedom from governmental imposition of religion upon the people within a state that is neutral on matters of belief."

"Secularism draws its intellectual roots from Greek and Roman philosophers such as Marcus Aurelius and Epicurus; medieval Muslim polymaths such as Ibn Rushd; Enlightenment thinkers such as Denis Diderot, Voltaire, Baruch Spinoza, John Locke, James Madison, Thomas Jefferson, and Thomas Paine; and more recent freethinkers, agnostics, and atheists such as Robert Ingersoll and Bertrand Russell."

"The term 'secularism' was first used by the British writer George Jacob Holyoake in 1851. He invented the term 'secularism' to describe his views of promoting a social order separate from religion, without actively dismissing or criticizing religious belief."

"In political terms, secularism is a movement towards the separation of religion and government (often termed the separation of church and state). This can refer to reducing ties between a government and a state religion, replacing laws based on scripture (such as the Torah and Sharia law) with civil laws, and eliminating discrimination on the basis of religion. This is said to add to democracy by protecting the rights of religious minorities."

Vs. Secualrize

From the Online Etymology Dictionary:
1610s, from secular + -ize. Related: Secularized; secularizing

secularization" first referred to the process of transferring property from ecclesiastical jurisdiction to that of the state or other nonecclesiastical authority. In this institutional sense, "secularization" still means the reduction of formal religious authority (e.g., in education). Institutional secularization has been fueled by the breakdown of a unified Christendom since the Reformation, on the one hand, and by the increasing rationalization of society and culture from the Enlightenment to modern technological society, on the other
