In 1925, Pope Pius XI established the Solemnity of Our Lord Jesus Christ, King of the Universe (formerly Christ the King).
Originally in October, it was moved by Pope Paul VI in 1969, to the last Sunday of Ordinary Time, preceding Advent. It is thus uniquely placed in the liturgical calendar.
In this positioning, it can be perceived as both forward looking to the birth of Christ, and retrospective, in reflecting on the ways the Church and church-goers could have better witnessed to the Good News of Christ. It is this state of reflection in which we enter the season of Advent and it is a reassurance of Christ’s supremacy above all.
