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.
In ordinary time—the liturgical season we’re in now—our parish has many years sung the simple ordinary in English from the third edition of the Roman Missal. In Lent (and sometimes in Advent) we have sung the same ordinary but in Latin.
The Lenten season begins this year on Ash Wednesday, February 17.
During Lent we refrain from singing the Gloria (except on Holy Thursday) and the Alleluia. These joyful chants are restored at the Easter Vigil arrives.
In Lent we sing some parts of the ordinary in Latin—notably the Sanctus (Holy, holy, holy) and Agnus Dei (Lamb of God)—for greater solemnity.
When the Kyrie (Lord have mercy) is sung, we’ll continue using the setting in Greek from the Roman Missal:
The Sanctus (Holy, holy, holy) we’ll sing has virtually the same tune as the English version:
After the consecration, we will sing the same memorial acclamation we’ve been using:
As with the Sanctus, the melody of the Agnus Dei (Lamb of God) we will sing is almost identical to the English version:
