Catholic Mass is Orthodox – Right Worship of the Father

Catholic Mass is Orthodox – Right Worship of the Father February 12, 2024

If you ask people why they go to Mass, you are sure to get a lot of answers. “I go because I want to receive the Eucharist.” “I go to spend time with family.” Others will remark “I want to hear the Word of God.” Someone else will say “I like the preaching,” Ok, maybe I just hope someone would answer that. However, all these answers fall short: Catholic Mass is about perpetuating the Paschal mystery. Mass is a sacrifice, in which we all participate, led by the priest. The Reformers of the 16th century could not accept this basic truth of the faith. Who is right: Luther and his followers, or the Catholic Church? In this article, I will explore how the Catholic Mass is a sacrifice.

From the Last Supper to the Passion

Jesus celebrated the Last Supper right before his Passion because he connected it so intimately with his sacrifice on the Cross. The Second Vatican Council Constitution on the Liturgy, Sacrosanctum Concilium, points out that the Mass is essentially a sacrifice in Number 47. The Catechism of the Catholic Church cites the entire paragraph.

At the Last Supper, on the night when He was betrayed, our Savior instituted the eucharistic sacrifice of His Body and Blood. He did this in order to perpetuate the sacrifice of the Cross throughout the centuries until He should come again, and so to entrust to His beloved spouse, the Church, a memorial of His death and resurrection: a sacrament of love, a sign of unity, a bond of charity, a paschal banquet in which Christ is eaten, the mind is filled with grace, and a pledge of future glory is given to us. (Constitution on the Sacred Liturgy Sacrosanctum Concilium, 47; quoted in Catechism of the Catholic Church, 1323)

We see four basic aspects of the Eucharist as memorial: it is sacrament, sign, bond, and banquet in which three things happen: Christ is eaten, our mind is filled with grace, and we receive a pledge of future glory.

Mass is Essentially a Sacrifice

In this article, I will concentrate on the Mass as essentially a sacrifice. The author of the Letter to the Hebrews makes it clear that the New Covenant begins with a sacrifice.

First, the establishment of a covenant (diatheke) requires death (Heb 9:16–17). Second, Hebrews is also clear that there is no forgiveness of sins without the shedding of blood (Heb 9:22). The author of Hebrews is emphatic that Christ’s sacrifice is patterned on the sacrifices of the Old Law, which required both death and blood. (Christian Washburn, “A Defense of St. Robert Bellarmine’s Definition of Sacrifice”)

Through the Mass, Jesus establishes the continuity between the Old and the New Covenant through the aspect of sacrifice. While the priest presents his sacrifice in an unbloody manner, it is real. The Eucharistic sacrifice shows us in a real way what it means for Jesus to die on the Cross. In a mysterious way, it makes us present at Calvary.

Martin Luther’s Dissent

Martin Luther highlighted his distaste for the celebration of the Eucharist in his criticism of the Church, particularly because of the sacrificial aspect. He suggested that it was something man-made and needed to disassemble it to respect the purity of the Gospel. In response, the Council of Trent  focused on the sacraments of the Eucharist and of the priesthood. Thus, they established firmly that the Mass is indeed a sacrifice.

Protestant theologians had multiple reasons for rejecting the Mass as a true and proper sacrifice. First, they objected that the Mass is a human work whereby we try to please God, which they believed impossible to do. Second, Protestant theologians viewed the Eucharistic sacrifice as detracting from the sufficiency of Christ’s sacrifice on the cross. Third, the sacrifice of the cross was the final sacrifice, and so there is no other necessary sacrifice in either Christianity or elsewhere. Fourth, they argued that the Mass cannot be a propitiatory sacrifice for the living and the dead, since only Christ’s death is propitiatory.(Christian Washburn, “A Defense of St. Robert Bellarmine’s Definition of Sacrifice”)

Purely Human Works Cannot Satisfy God

Taking into account their point of view, the Reformers are partially right. Much of what they do are human works designed to please God, so it is natural that they interpret the Catholic Mass in the same way. There is a big difference, however, because the Mass has been given to the Church by Jesus himself in the Last Supper and his bloody sacrifice on the Cross, which is presented in the Mass in an unbloody manner.

The Council of Trent responded to the Reformers by clarifying Catholic doctrine on subjects such as the Eucharist and the priesthood. One of the pre-eminent theologians in this debate was the Jesuit, Cardinal Robert Bellarmine. One of the problems that Cardinal Bellarmine addressed was that the term “sacrifice” in the Old Testament had a real and sensible meaning. He argued that we dilute the concept of sacrifice into a generalized sense of “any ceremony or good work offered to God to worship Him” as  Melancthon proposed (Melancthon, The Apology of the Augsburg Confession, XXIV). Bellarmine knew that a sacrifice of this kind is something deeper than what the Reformers proposed.

Bellarmine’s Response

Rooted in the Revelation of God in the Old Testament, Bellarmine states  firmly in his Disputationes de Controversiis Christianae fidei adversus huius temporis haereticos that Jesus has already completed his sacrifice on the Cross, but that this same sacrifice is still present each time we celebrate Mass. “For Bellarmine altar and priesthood are co-relative. If there is to be a true and proper sacrifice, there must be a true and proper priesthood” (Christian Washburn, “A Defense of St. Robert Bellarmine’s Definition of Sacrifice”). If Christianity were to exist without sacrifice, it would be a departure from what God has commanded through Judaism.

Orthodoxy of the Catholic Mass

We know the term “right worship” more commonly through its transliteration from the Greek: “orthodoxy.” Orthodoxy – right worship – can take place only when we are worshiping God in the way that he himself sets down. This is why the Mass is perfect prayer, and why we cannot and should not change its nature. If Jesus established the Mass as a sacrifice, it is a matter of Christian obedience to treat it as such.

How do we live this out in our everyday life? Do we approach the altar with reverence and awe, recognizing that we are encountering the King of Kings, who became man for our sake and died on the cross to save us from our sins? When we realize that we are offering orthodox sacrifice through our worship at Mass, we can begin to enter into the Eucharistic mystery and become more fitting worshipers of Christ the Lord.
