A cultural Christian is a secular or irreligious individual who still significantly identifies with Christian culture. Deists of the 18th and early 19th centuries, such as Napoleon and various Founding Fathers of the United States, similarly considered themselves part of Christian culture, despite their doubts about the divinity of Jesus.

Those belonging to charismatic movements use the term to describe individuals whose spiritual understanding or practice they see as underdeveloped, superficial, or lacking obvious fervor.

The term "cultural Christian" (also "nominal Christian") is a term used in Christian fundamentalism and the Christian Charismatic Movement, for Christians who are not "born again" (i.e. who have not experienced a personal religious conversion). The term was coined in the 1970s, and popularized in the 1980s and 1990s. Contrasting terms are "biblical Christian", "committed Christian", "converted Christian" or "believing Christian".

A related concept is that of a "nominal" Christian, whom the Lausanne Committee for World Evangelization defines as "a person who has not responded in repentance and faith to Jesus Christ as his personal Saviour and Lord." The LCWE notes that such a one "may be a practising or non-practising church member. He may give intellectual assent to basic Christian doctrines and claim to be a Christian. He may be faithful in attending liturgical rites and worship services, and be an active member involved in church affairs." The LCWE also suggests that nominal Christianity "is to be found wherever the church is more than one generation old."

Clinton Richard Dawkins, FRS, FRSL (born 26 March 1941), known as Richard Dawkins, is a British ethologist, evolutionary biologist and author. He is an emeritus fellow of New College, Oxford, and was the University of Oxford's Professor for Public Understanding of Science from 1995 until 2008.

Dawkins came to prominence with his 1976 book The Selfish Gene, which popularised the gene-centered view of evolution and introduced the term meme. In 1982 he introduced an influential concept into evolutionary biology, presented in his book The Extended Phenotype, that the phenotypic effects of a gene are not necessarily limited to an organism's body, but can stretch far into the environment, including the bodies of other organisms.

Dawkins is an atheist, a vice president of the British Humanist Association, and a supporter of the Brights movement. He is well known for his criticism of creationism and intelligent design. In his 1986 book The Blind Watchmaker, he argued against the watchmaker analogy, an argument for the existence of a supernatural creator based upon the complexity of living organisms. Instead, he described evolutionary processes as analogous to a blind watchmaker. He has since written several popular science books, and makes regular television and radio appearances, predominantly discussing these topics. In his 2006 book The God Delusion, Dawkins contends that a supernatural creator almost certainly does not exist and that religious faith is a delusion—"a fixed false belief." As of January 2010 the English-language version has sold more than two million copies and had been translated into 31 languages.

Nora Lam (September 4, 1932 – February 2, 2004), was a Chinese Protestant Christian minister to China, and founder of Nora Lam Ministries International (NLMI). Lam was born in China and lived there until her escape to Hong Kong at age 26.

Nora Lam was born September 4, 1932 in a missionary hospital in Beijing, China. Abandoned at birth, she was adopted six months later by Dr. and Mrs. H.T. Sung, a prominent couple in Shanghai. Her adoptive mother was a member of one of Shanghai's wealthiest families. Her adoptive father was born September 11, 1900 and was educated in France, where he received some Catholic instruction. He, however, was not religious. Lam was given the name Neng Yee Sung, and she described her childhood as being spoiled and pampered.

In 1937, the conflict on the Marco Polo Bridge in Beijing led to the start of war with Japan. When Japanese forces reached Shanghai in 1939, Sung, then age 7, and her family fled their home to go live at her step-grandmother's home in Shanghai's French Concession. In 1941, she attended the McTyeire Home and School for Girls, where she first heard of Christianity. During her time there, Sung had a vision of a guardian angel, appearing in the form of an old man. She felt this guardian angel advised her throughout her life.

William Lane Craig (born August 23, 1949) is an American analytic philosopher, philosophical theologian, and Christian apologist. He is known for his work in the philosophy of religion, philosophy of time, and the defense of Christian theism. One of his most notable contributions to the philosophy of religion is his defense of the Kalām cosmological argument, which is the most widely discussed argument for the existence of God in contemporary Western philosophy. In theology, he has also defended Molinism and the belief that God is, since Creation, subject to time.

Craig has authored or edited over 30 books, including The Kalām Cosmological Argument (1979), The Cosmological Argument from Plato to Leibniz (1980), Theism, Atheism, and Big Bang Cosmology (with Quentin Smith, 1993), Philosophical Foundations for a Christian Worldview (with J.P. Moreland, 2003) and Reasonable Faith: Christian Truth and Apologetics (3d edition, 2008).

Craig received a Bachelor of Arts degree in communications from Wheaton College, Illinois, in 1971 and two summa cum laude master's degrees from Trinity Evangelical Divinity School in Deerfield, Illinois, in 1975, in philosophy of religion and ecclesiastical history. He earned a Ph.D. in philosophy under John Hick at the University of Birmingham, England in 1977 and a Th.D. under Wolfhart Pannenberg at the University of Munich in 1984.

William Lane (6 September 1861 – 26 August 1917) was a journalist, advocate of Australian labour politics and a utopian.

Lane was born in Bristol, England, eldest son of James Lane, from Ireland a Protestant Master Gardener, and his English wife Caroline, née Hall. When Lane was born his father was earning a miserable wage, but later his circumstances improved and he became an employer. The boy was educated at Bristol Grammar School and showed ability, but he was sent early to work as an office boy. Lane's mother died when he was 14 years of age, and at age 16 he migrated to Canada, then to the United States, where he worked first as a printer, then as a reporter for the Detroit Free Press (1881), there meeting his future wife Ann MacGuire. In 1885 they migrated to Brisbane, Australia, where Lane immediately got work as a feature writer for the weekly newspaper Queensland Figaro, then as a columnist for the newspapers Brisbane Courier and Evening Telegraph, using a number of pseudonyms ("Lucinda Sharpe", which some consider to be the work of Annie Lane, William Wilcher and "Sketcher").
