One of the criticisms of the Mass is that it constitutes a re-sacrificing of Jesus. This, however, is a false assertion. The sacrifice of the Mass is the "once for all" sacrifice of Jesus on the cross. In the Old Testament there are two parts to a sacrifice; the death of the victim, and the offering up of the fruits by the High Priest. The same is true in the New Testament. Jesus' death took place at one point in time and it cannot be repeated. Yet, the fruits of His sacrifice must be applied to every believer past, present and future. In the book of Revelation, Jesus, who is in heaven, is referred to 29 times as the "Lamb." The Word of God portrays Jesus as a sacrificial lamb because, as the High Priest of the New Covenant, He is continually offering up the fruits of His Sacrifice. We partake of those fruits when we participate in the Mass. Ironically, some of the most vocal critics of the Mass claim to be "washed by the blood of the Lamb" – blood that was shed two thousand years ago. If you asked them if they were re-sacrificing Jesus they would say "no, we are receiving the benefits of His once for all time sacrifice" (Hebrews 10:12). And so it is with the Mass.
The Mass is a ritual. Many Protestants don't believe in performing rituals. They claim that Christianity, unlike Judaism, is not a religion. They say that it is a relationship with God; therefore rituals are unnecessary. However, Christianity is a religion, a religion where believers can have a personal relationship with God. In James 1:26-27 we read the following: "If anyone thinks he is religious, and does not bridle his tongue but deceives his heart, this man's religion is vain. Religion that is pure and undefiled before God and the Father is this: to visit orphans and widows in their affliction, and to keep oneself unstained from the world." When James calls Christianity a religion, he is commenting on its nature. The Greek word that is translated into "religion" is threskeia(θρησκεία). Threskeia means ceremonial observance, which is what a ritual is. This is the same word used by Paul to describe Judaism in Acts 26:5. If rituals have no place in Christianity, why does the Word of God refer to it in ritualistic terms? Of course Christianity is more than just a bunch of rituals. When we are open to the grace that is received at Mass and in the sacraments we cannot help but to be the person God wants us to be.
Malachi 1:11 speaks prophetically of the Mass: "From the rising of the sun to its setting my name is great among the nations, and in every place incense is offered to my name, and a pure offering, for my name is great among the nations, says the Lord of hosts." The sacrifice spoken of is not the Judaic sacrifice. The passage refers to a pure sacrifice that will take place everywhere among the nations (Gentiles). This makes perfect sense as we are living in "the times of the Gentiles" (Luke 21:24). Psalm 110  provides even more detail. Verse 4 reads, "The Lord has sworn and will not change His mind, 'You [Jesus] are a priest forever after the order of Melchizedek.'" In Genesis 14:18 Melchizedek offered a sacrifice of bread and wine. So Psalm 110 is a prediction that Jesus would offer a perpetual sacrifice involving bread and wine. He does this at the Last Supper and commands that His apostles do the same. Consequently, the Sacrifice of the Mass involves the offering of bread and wine (not grape juice).
The early Church understood the Mass to be a true sacrifice. Clement, the fourth bishop of Rome, wrote in the year 95 AD, "Our sin will not be small if we eject from the episcopate those who blamelessly and holily have offered its sacrifices" (1 Clement 44:4). A few years later in the year 110 AD, Ignatius of Antioch said the following: "Make certain, therefore, that you all observe one common Eucharist, for there is but one body of our Lord Jesus Christ, and but one cup of union with His blood, and one single altar of sacrifice, even as there is also but one bishop, with his clergy and my own fellow servitors, the deacons" (Letter to the Philadelphians No. 4)
A close examination of the Mass reveals that it is saturated with Scripture. From the greeting to the dismissal we find verse after verse drawing us deeper into the Word of God. One of many examples is "The Gloria."
Glory to God in the highest, and peace to his people on earth (cf. Lk. 2:14). Lord God, heavenly King, almighty God and Father, (Rev. 19:6) we worship you (Rev. 22:9), we give you thanks (Eph. 5:20), we praise you for your glory (Rev. 7:12). Lord Jesus Christ, only Son of the Father (2 Jn. 3), Lord God, Lamb of God, you take away the sin of the world: have mercy on us (cf. Jn. 1:29); you are seated at the right hand of the Father: receive our prayer (Rom. 8:34). For you alone are the Holy One (cf. Lk. 4:34), you alone are the Lord (Rev. 15:4), you alone are the most High, Jesus Christ (Lk. 1:32), with the Holy Spirit, in the glory of God the Father. Amen (cf. Jn. 14:26).
There are two parts to the Mass. The liturgy of the Word and the Liturgy of the Eucharist. During the Liturgy of the Word there are three Scripture readings. One from the Old Testament, one from the epistles or New Testament letters, and one from the Gospels. The three readings are usually connected in some way. This shows us how Scripture works together as a whole.
The Church also has three liturgical cycles. Each of these cycles lasts a year. Each cycle features a different set of readings from the Bible. At the end of the three years Catholics have heard the vast majority of the Bible read and preached upon. This is done so that Catholics will have a balanced and accurate view of what is taught by the Scriptures.
In the Liturgy of the Eucharist we partake of the Lords Supper. Some are opposed to the Mass because of the Catholic belief that the bread and the wine become the body and blood of Jesus. I address this issue in detail in another essay (The Eucharist). However, to touch on it briefly; Are we wrong to say what Jesus said? Are we wrong to do what He commanded us to do? That it boggles the natural mind is irrelevant. Speaking the universe into existence boggles the natural mind. But we know from the word of God that it happened. God always accomplishes what He says He will. Another example is when He said He would raise His own dead body (John 2:19). As He says in the book of Isaiah: "So shall my word be that goes forth from my mouth; it shall not return to me void, but shall do my will, achieving the end for which I sent it" (Isaiah 55:11). That wouldn’t just refer to some of what God says but to all of it. As Jesus Himself said: "It is written, ‘Man shall not live by bread alone, but by every word that proceeds from the mouth of God" (Matthew 4:4).
So when Jesus says that He will raise his own dead body it happens. Likewise when He says at the Last Supper that the Bread and the wine has become that same body, it happens. And of course it only stands to reason that when we do likewise, as He commanded, it happens. Manipulating the Word of God to appeal to the natural mind serves no useful purpose: "For we walk by faith, not by sight (2 Corinthians 5:7). The Last Supper was the first Mass. That was the belief of the Early Church and that is the belief of the Catholic Church.
But, some will say, "I don't get anything out of the Mass." To the uninformed person, a candy bar seems more exciting than a million-dollar check. The colorful wrapper is certainly more pleasing to the eye, and you have a piece of candy inside. How can a plain piece of paper with handwriting on it compete with that? To the uninformed, the Mass may be viewed similarly. If you don't know what it is all about you aren't going to understand its importance and you aren't going to be open to what it has to offer. Thus you won't get anything out of it.
The Catechism of the Catholic Church wisely points out that our Yes to Jesus Christ is twofold: a trustful abandonment to God and a loving assent to all that he has revealed to us. This is possible only by means of the action of the Holy Spirit (Nos. 150,176). If you are one of those who "doesn't get anything out of the Mass," learn more about it and pray to the Holy Spirit for the grace to be open to all that it has to offer. It will change your life.
