While every Feast of Christ the King is special, 2025's celebration is particularly momentous. The titular feast of the Institute of Christ the King Sovereign Priest, the Feast of Christ the King recognizes the universal sovereignty of Our Lord Jesus Christ and affirms the mission of the Institute to spread the reign of Christ the King to every corner of human existence, including the senses. ​ The Christ the King Music Festival serves to highlight this annual feast. Augmenting the closing Solemn High Mass with orchestral forces, it strives to extend the sacred solemnity to include concerts, dancing, and actual feasting, engaging every human sense with the divine.   ​ This year's theme is Gregorian Chant, the only musical form truly unique to the Roman Rite of Christendom. Besides the customary Gregorian Proper of Mass, this year's Solemn High Mass will feature choral repertoire will whose compositional DNA is rooted deeply in the Gregorian idiom.  Pope Pius XI promulgated the Feast of Christ the King in 1925. All singers are invited to participate and help make the 100th anniversary of the feast the greatest Christ the King Music Festival of our time. ​
