Order of the Mass

What is the “Mass”?

The Mass, or celebration of the Eucharist, is the principal liturgical action in the Roman Catholic Church. The word “Mass” comes from the Latin word, missa meaning “mission” or “sending” because the liturgy is to send forth the faithful to bring forth the Good News of Jesus and to be His sacramental presence in the world.

The Mass was established by the Lord Jesus at the Last Supper on the night before He died for us. In this celebration, we participate in the mystery of salvation by remembering the sacrificial death and resurrection of the Lord.

The Liturgy of the Word and the Liturgy of the Eucharist

There are two major parts of the Mass: the Liturgy of the Word and the Liturgy of the Eucharist.

The Liturgy of the Word is the first major component of the Mass during which selections from the Scriptures are proclaimed. A teaching, known as the “homily” is given using the Scriptures of the day to explain the Christian life to the faithful. On Sundays and major feasts of the Church, the faithful profess their faith using the formula known as the “Nicene Creed.” In certain instances, the Apostles’ Creed may be used in its place. The Liturgy of the Word concludes with the Prayer of the Faithful during which the people exercise their royal priesthood by interceding for the needs of the whole world.

The Liturgy of the Eucharist forms the second major part of the Mass. It begins with several minor preparatory rites and culminates with the Eucharistic Prayer. During this prayer, the priest invokes the action of the Holy Spirit (epiclesis) to change the bread and wine into the Body and Blood of Christ. After several more minor rites, members of the assembly who are Roman Catholic and not in the state of serious sin, are invited to receive the Body and Blood of the Lord.
