The Source and Summit
Elements of the Mass
The Mass can look, to a newcomer, like a long sequence of standing, sitting, and kneeling. In fact every gesture and word follows a deliberate structure that has shaped Christian worship since the earliest centuries.
Four Movements
The shape of the Mass
Every Mass unfolds in four parts: we gather, we listen, we offer, and we are sent.
IThe Introductory Rites+
The Mass begins by gathering a room full of individuals into a single worshiping body. The priest and ministers process in during the Entrance, greet the assembly in God's name, and lead the Penitential Act — a brief, honest acknowledgment of sin ("I confess to almighty God...") before approaching the altar. On most Sundays, the ancient hymn of praise, the Gloria, follows ("Glory to God in the highest..."), and the rites close with the Collect, a prayer that gathers the intentions of everyone present into one voice.
IIThe Liturgy of the Word+
Scripture is proclaimed: normally a reading from the Old Testament, a Psalm sung or recited as a response, a reading from the New Testament epistles, and finally the Gospel, for which the whole congregation stands. The priest or deacon then preaches a Homily, connecting the readings to the life of the Church and the lives of those present. On Sundays and solemnities, the congregation professes the Creed together, and the Liturgy of the Word closes with the Prayers of the Faithful, interceding for the Church, the world, the suffering, and the local community.
IIIThe Liturgy of the Eucharist+
Bread and wine are brought forward and prepared at the altar during the Offertory, along with the collection, which represents the offering of the people's own lives and work. The priest then prays the Eucharistic Prayer, the heart of the Mass, culminating in the words of consecration Christ spoke at the Last Supper — the moment Catholics believe the bread and wine truly become the Body and Blood of Christ. After the Our Father and a sign of peace, the assembly receives Him in Holy Communion.
IVThe Concluding Rites+
The Mass closes briefly: a final blessing, and the dismissal — historically in Latin, "Ite, missa est" ("Go, you are sent"), the very phrase that gives the Mass its English name. The word is not "ended," but "sent" — worship does not conclude at the door of the church; it is meant to be carried out into ordinary life.
