Here are some of the proper texts—those that change with every Sunday or solemnity—to be sung for this Mass:
Introit: Behold, the Lord, the Mighty One has come; and kingship is in his grasp, and power and dominion. (Cf. Malachi 3:1; I Chronicles 19:12)
Responsorial psalm: Lord, every nation on earth will adore you. (Cf. Psalm 72:11)
Offertory: The kings of Tharsis and the islands shall offer presents; the kings of the Arabians and of Saba shall bring gifts. And all kings of the earth shall adore him; all nations shall serve him. (Psalm 72:10-11)
Communion: Vidimus stellam ejus in Oriente, et venimus cum muneribus adorare Dominum. (Cf. Matthew 2:2)
Translation: We have seen his star in the east and are come to adore the Lord.
Recessional hymn: As With Gladness Men of Old
