Yes! No matter where or when you go to Mass, you will always know what you’re going to get. 
 
Jesus Christ celebrated the first Mass with His disciples at the Last Supper, the night before He died. He commanded His disciples, “Do this in remembrance of me” (Luke 22:19). The celebration of the Mass then became the main form of worship in the early Church, as a reenactment of the Last Supper, as Christ had commanded. 
 
Each and every Mass since commemorates Jesus’ sacrifice on the cross through the Holy Eucharist. Because the Mass “re-presents” (makes present) the sacrifice on Calvary, Catholics all around the world join together to be made present in Christ’s timeless sacrifice for our sins. There is something fascinating about continuing to celebrate the same Mass—instituted by Christ and practiced by the early Church—with the whole community of Catholics around the world…and in heaven.

In Matthew 26, Mark 14, and Luke 22, Jesus says of the bread, “This is my body.” He says of the wine, “This is my blood.” Rather than saying, “this is symbolic of,” or “this represents,” He says, “this IS.” In John 6, He repeats Himself, like He does nowhere else in Scripture, to emphasize the fact that He expects us to eat His flesh and drink His blood and that His flesh is real food and that His blood is real drink. There are several facts that point to the literal meaning that Christ meant to convey here. Fact #1: The Jews took him literally in verse 52. Fact #2: His disciples took him literally in verse 60. Fact #3: the Apostles took him literally in verses 67-69. If everyone who heard him speak at the time took Him literally, then all of us today, 2000 years after the fact, are also called to take Him literally, in accordance with the Scriptures. Also, in verse 51, Jesus says that the bread which He will give for the life of the world is His flesh. When did He give His flesh for the life of the world? On the Cross. We know that Jesus was not speaking symbolically here. Since we conclude that Jesus was speaking literally of dying on the Cross, we should also conclude that He meant what He said about eating His flesh and drinking His blood. 
 
When we believe that Jesus is talking symbolically here in John 6, we come across a real problem when it comes to John 6:51. Did Jesus give His real flesh and blood for the life of the world, or was it only His symbolic flesh and blood?
