The Solemnity of Our Lord Jesus Christ, King of the Universe is the last Sunday of the liturgical year before a new liturgical year begins with the first Sunday of Advent. Pope Pius XI instituted this feast for the universal Church during the Jubilee Year of 1925 in his encyclical Quas Primas in order to combat a global rise in the evils of atheism, secularism, and communism due to the majority of mankind having rejected Christ and his law. He declared that without honoring the authority of Christ as King, the world would have no hope of lasting peace. His goal was that all world leaders, governments, and nations would honor Christ the King in their civil and political affairs, as well as uphold the rights of His Church, and that the faithful would be reminded that Jesus must reign as King in each individual heart, mind, will, and body.
