Christianity (from the Ancient Greek: Χριστιανός Christianos) is a monotheistic and Abrahamic religion based on the life and teachings of Jesus as presented in canonical gospels and other New Testament writings. Adherents of the Christian faith are known as Christians.

Christians generally believe Jesus is the Son of God, God having become human and the saviour of humanity. Because of this, Christians commonly refer to Jesus as Christ or Messiah. Jesus' ministry, sacrificial death, and subsequent resurrection, are often referred to as the Gospel message ("good news"). In short, the Gospel is news of God the Father's eternal victory over evil, and the promise of salvation and eternal life for all people, through divine grace. Jesus stated that love is the greatest commandment: "Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind [and] thou shalt love thy neighbour as thyself."

Worldwide the three largest groups of Christianity are the Roman Catholic Church, the Eastern Orthodox churches, and the various denominations of Protestantism. The Roman Catholic and Eastern Orthodox patriarchates split from one another in the East–West Schism of 1054 AD, and Protestantism came into existence during the Protestant Reformation of the 16th century, splitting from the Roman Catholic Church.

Frederick Antony Ravi Kumar Zacharias (born 1946) is an Indian-born, Canadian-American evangelical Christian apologist. Zacharias is the author of numerous Christian books, including Gold Medallion Book Award winner Can Man Live Without God? and bestsellers Light in the Shadow of Jihad and The Grand Weaver. He is the founder and chairman of the board of Ravi Zacharias International Ministries, host of the radio programs Let My People Think and Just Thinking, and visiting professor at Wycliffe Hall of Oxford, where he teaches apologetics and evangelism. Zacharias studied as a visiting scholar at Cambridge University and held the chair in Evangelism and Contemporary Thought at Alliance Theological Seminary from 1981 to 1984. Commentator Chuck Colson referred to Zacharias as "the great apologist of our time."

Zacharias was born in Madras, India. Zacharias claims descent from a woman (of the Nambudiri Brahmin caste) and a low caste Boatman. Missionaries spoke to one of his ancestors about Christianity and thereafter the family was converted. Zacharias grew up in a nominal Anglican household, and he himself was an atheist until the age of 17, when he unsuccessfully tried to commit suicide by swallowing poison. While in the hospital, a local Christian worker brought him a Bible and instructed his mother to read to him out of John 14. Zacharias says that it was John 14:19 that touched him and caused him to commit his life to Christ.

Francis Gregory Stafford (born February 9, 1948), usually known as Greg Stafford, is an American game designer, publisher and shaman.

Stafford is perhaps most famous as the creator of the fantasy world of Glorantha, but is also a prolific games designer - he was designer of Pendragon, he was co-designer of the RuneQuest, Ghostbusters, Prince Valiant and HeroQuest role-playing systems, founder of the role-playing game companies Chaosium and Issaries, designer of the White Bear and Red Moon, Nomad Gods, King Arthur’s Knights and Elric! board games, and co-designer of the King of Dragon Pass computer game.

Greg Stafford's interest in roleplaying and gaming originated in his adolescent fascination with mythology. During his adolescent years he read anything he could find on the subject, and when he exhausted the libraries, he started to write his own stories in his freshman year at Beloit College, in 1966. This was the start of the world of Glorantha.

Around 1974, Stafford created White Bear and Red Moon, a board game about the violent struggle between several cultures in the Dragon Pass region of Glorantha. In essence the game centered around the conflict between the barbarian Kingdom of Sartar and the invading Lunar Empire, which has remained a central theme for Gloranthan publications since then.
