Christ the King is a title of Jesus based on several passages of Scripture. It is used by most Christians. The Roman Catholic Church, together with many Protestant denominations, including the Anglicans, Presbyterians, Lutherans and Methodists, celebrate the Feast of Christ the King on the last Sunday of the liturgical year (before a new year begins with the first Sunday of Advent, the earliest date of which is 27 November). The Feast of Christ the King is thus on the Sunday that falls between 20 and 26 November, inclusive. Originally, the liturgical calendar had this feast on the last Sunday of October prior to All Saints' Day, where it is still celebrated in the Extraordinary form of the Roman Rite. The title "Christ the King" is also frequently used as a name for churches, schools, seminaries, hospitals and religious institutes.
The name is found in various forms in scripture: King (John 18:36-37), King eternal (1 Timothy 1:17), King of Israel (John 1:49, Mt. 27:42, Mark 15:32), King of the Jews by Romans and Magi (Mt. 2:2, Mt. 27:11, cf. John 18:33-37), King of kings (1 Tim 6:15; Rev. 19:16), King of the ages (Book of Revelation 15:3) and Ruler of the kings of the Earth (Rev. 1:5).
Christ's kingship was addressed in the encyclical Quas Primas of Pope Pius XI, published in 1925, which has been called "possibly one of the most misunderstood and ignored encyclicals of all time." The Pontiff's encyclical quotes with approval Cyril of Alexandria, noting that Jesus' kingship is not obtained by violence: "'Christ,' he says, 'has dominion over all creatures, a dominion not seized by violence nor usurped, but his by essence and by nature.'" Pope Pius XI instituted the feast of Christ the King in 1925 to remind Christians that their allegiance was to their spiritual ruler in heaven as opposed to earthly supremacy, which was claimed by Benito Mussolini.
Pope Benedict XVI has remarked that Christ's kingship is not based on "human power" but on loving and serving others. The perfect exemplar of that acceptance, he pointed out, is the Virgin Mary. Her humble and unconditional acceptance of God's will in her life, the Pope noted, was the reason that "God exalted her over all other creatures, and Christ crowned her Queen of heaven and earth."
