Christianity and other religions appear to share some elements. In a look at Christianity's relationship with other world religions, this article investigates the differences and similarities of Christianity to other religions.

Generally Christians believe that religious pluralism is heresy and contradicts the Bible. Some Christians have argued that religious pluralism is an invalid or self-contradictory concept. Maximal forms of religious pluralism claim that all religions are equally true, or that one religion can be true for some and another for others. Some, but by no means all, Christians hold such pluralism to be logically impossible.Roman Catholicism believes that while it is the fullest and most complete revelation of God to Man, other Christian denominations have also received genuine revelation from God, although partial and incomplete. Other Christian traditions believe that God is so big that there are many varied and valid paths to God.^{[clarification needed]}

Although Calvinists believe God and the truth of God cannot be plural, they also believe that those civil ordinances of man which restrain man from evil and encourage toward good, are ordinances of God (regardless of the religion, or lack of it, of those who wield that power). Christians are obligated to be at peace with all men, as far as it is up to them, and to submit to governments for the Lord's sake, and to pray for enemies.

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").

Stephen Tyrone Colbert ( /koʊlˈbɛər/ or /ˈkoʊlbərt/; born May 13, 1964) is an American political satirist, writer, comedian, television host, and actor. He is the host of Comedy Central's The Colbert Report, a satirical news show in which Colbert portrays a caricatured version of conservative political pundits.

Colbert originally studied to be an actor, but became interested in improvisational theatre when he met famed Second City director Del Close while attending Northwestern University. He first performed professionally as an understudy for Steve Carell at Second City Chicago; among his troupe mates were comedians Paul Dinello and Amy Sedaris, with whom he developed the critically acclaimed sketch comedy series Exit 57.

Colbert also wrote and performed on the short-lived Dana Carvey Show before collaborating with Sedaris and Dinello again on the cult television series Strangers with Candy. He gained considerable attention for his role on the latter as closeted gay history teacher Chuck Noblet. It was his work as a correspondent on Comedy Central's news-parody series The Daily Show, however, that first introduced him to a wide audience.

Paul David Washer (born 1961) is the Founder/Director & Missions Coordinator of HeartCry Missionary Society which supports indigenous missionary work. He is also a Southern Baptist itinerant preacher. Washer's sermons tend to have an evangelistic focus on the gospel and the doctrine of the assurance of salvation, and he frequently speaks against practices such as the sinner's prayer, and a focus on numerical church growth.

Washer had a born again experience while studying to become an oil and gas lawyer at the University of Texas. Upon graduation, he attended Southwestern Baptist Theological Seminary and achieved a Master of Divinity degree. He then moved to Peru to become a missionary for 10 years, after which he returned to the United States. Washer resides in Radford, Virginia, where he lives with his wife and three children.

Washer's sermons often focus on the character of Christ and how a person is saved from hell. According to Washer, a person is saved through faith alone, but the evidence of a person's repentance is by walking with Jesus. Washer claims that most people who profess a belief in Christianity aren't truly saved. Washer blames preachers, as he claims many preachers often say a person is saved without looking for evidence of repentance in that person's life.
