The Solemnity of Our Lord Jesus Christ, King of the Universe, commonly referred to as the Feast of Christ the King, Christ the King Sunday or Reign of Christ Sunday, is a feast in the liturgical year which emphasises the true kingship of Christ. The feast is a relatively recent addition to the liturgical calendar, instituted in 1925 by Pope Pius XI for the Roman Rite of the Catholic Church. In 1970 its Roman Rite observance was moved from October to the last Sunday of Ordinary Time and thus to the end of the liturgical year. The earliest date on which the Feast of Christ the King can occur is 20 November and the latest is 26 November. The Lutheran, Anglican, Moravian, Methodist, Nazarene, Reformed and United Protestant churches also celebrate the Feast of Christ the King, which is contained in the Revised Common Lectionary; the Methodist, Anglican and Presbyterian Churches often observe this as part of the liturgical season of Kingdomtide, which runs between the Fourth Sunday before Advent and the Feast of Christ the King. It is also observed on the same computed date as the final Sunday of the ecclesiastical year, the Sunday before the First Sunday of Advent, by Western Rite parishes of the Russian Orthodox Church Outside Russia. Roman Catholics adhering to the Extraordinary Form of the Roman Rite use the General Roman Calendar of 1960 and continue to observe the Solemnity on the date established in 1925, the final Sunday of October. Origin in patristics According to Cyril of Alexandria, Christ "has dominion over all creatures, a dominion not seized by violence nor usurped, but his by essence and by nature. His kingship is founded upon the hypostatic union. From this it follows not only that Christ is to be adored by angels and men, but that to him as man angels and men are subject, and must recognize his empire; by reason of the hypostatic union Christ has power over all creatures." The Feast of Christ the King has an eschatological dimension pointing to the end of time when the kingdom of Jesus will be established in all its fullness to the ends of the earth. It leads into Advent, when the Church anticipates Christ’s second coming. Observance Roman Catholic Church Pope Pius XI instituted the Feast of Christ the King in his encyclical Quas primas of 1925, in response to growing secularism
