CRISTO REY- CHRIST THE KING
Pope Pius XI instituted the Feast of Christ the King in his encyclical Quas primas of 1925, in response to growing secularism and nationalism.
The title of the feast was "Domini Nostri Jesu Christi Regis" ( of Our Lord Jesus Christ the King), and the date was established as "the last Sunday of the month of October – the Sunday, that is, which immediately precedes the Feast of All Saints". In Pope John XXIII's revision of the calendar in 1960, the date and title were unchanged but, according to the simplification of the ranking of feasts, it was classified as a feast of the first class.
In his motu proprio Mysterii Paschalis of 1969, Pope Paul VI amended the title of the Feast to "D. N. Iesu Christi universorum Regis" (Our Lord Jesus Christ King of the Universe). He also moved it to the new date of the final Sunday of the liturgical year, before the commencement of a new liturgical year on the First Sunday of Advent (the earliest date for which is 27 November). Through this choice of date "the eschatological importance of this Sunday is made clearer". He assigned to it the highest rank of "solemnity".
Anglican and Protestant Churches
Those churches that use the Revised Common Lectionary observe Christ the King Sunday as the final Sunday of their liturgical year.  These churches include most Anglican and major mainline Protestant groups, including the Church of England, Episcopal Church, Anglican Church in North America, Evangelical Lutheran Church in America and other Lutheran groups, United Methodist Church and other Methodist groups, Presbyterian Church (U.S.A.), the United Church of Christ, and the Moravian Church. Some, such as the Uniting Church in Australia refer to it in non-gendered terms as feast of The Reign of Christ.
