Solemnity of Christ the King
The Feast of Christ the King was established by Pope Pius XI in 1925 as an antidote to secularism, a way of life which leaves God out of man's thinking and living and organizes his life as if God did not exist. The feast is intended to proclaim in a striking and effective manner Christ's royalty over individuals, families, society, governments, and nations.
Today's Mass establishes the titles for Christ's royalty over men: 1) Christ is God, the Creator of the universe and hence wields a supreme power over all things; "All things were created by Him"; 2) Christ is our Redeemer, He purchased us by His precious Blood, and made us His property and possession; 3) Christ is Head of the Church, "holding in all things the primacy"; 4) God bestowed upon Christ the nations of the world as his special possession and dominion.
