At every Mass we sing or say the words of the Ordinary (the unchangeable parts of the Mass), for example, the Gloria; Holy, holy, holy; and Lamb of God.
The Mass also includes what are called the propers—texts that change for each Sunday and solemnity. These include the introit (entrance chant), the responsorial psalm, the offertory chant, and the Communion chant.
Here are the proper texts to be sung on October 11, the 28th Sunday in ordinary time, at the 8 and 10 a.m. Masses:
Introit: If you, O Lord, should mark iniquities, Lord, who could stand? But with you is found forgiveness, O God of Israel. (Psalm 130:3-4)
Responsorial psalm: I shall live in the house of the Lord all the days of my life. (Psalm 23:6)
Offertory: Remember me, O Lord, you who rule above all power; and give a well-ordered speech in my mouth, that my words may be pleasing in the sight of the prince. (Esther 14:12-13)
Communion: The rich suffer want and go hungry, but those who seek the Lord lack no blessing. (Psalm 34:11)
The recessional hymn for the 10 a.m. Mass will be Holy, holy, holy.
