The Ordinary of the Mass (Kyrie, Gloria, Credo, Sanctus, Benedictus, Agnus Dei) is the set of unchanging texts for each Sunday and feast day Mass.

The Propers (Introit, Gradual / Alleluia / occasional Tract, Offertory, Communion) are portions of the Mass whose texts vary according to each Sunday or feast. The Scripture readings (Epistle and Gospel) also vary at each Mass.

During a High Mass, the priest and choir sing the Ordinary and the Propers in Latin.

During a Low Mass, the priest recites the Ordinary and Propers. The choir and congregation may sing Latin and English hymns to accompany the liturgical action at the Entrance, Offertory, Communion and Recessional.

Holy Communion
The first row of pews in front of the church will be reserved for distribution of Holy Communion.

Please note, it is customary at a Tridentine Mass for Holy Communion to be received kneeling and on the tongue.

The communicant does not say, "Amen," because it is included when the priest says, "Corpus Domini nostri Jesu Christi custodiat animam tuam in vitam aeternam. Amen." ("May the body of our Lord Jesus Christ preserve your soul unto life everlasting. Amen.")
