Because he cleanses me of the temporal penalties for my forgiven /venial sins, when I licitly receive Him in the Eucharist. Weekly, if I go to Mass weekly. I missed 11 eleven weeks of Him doing that for me.
Catholics believe that the Lord’s Supper is a sacrifice, a sacrifice every Mass where through the priest the wafers turn into Jesus’ body. Catholics believe they are experiencing a miracle when the priest does this.
Read what the word of God says. The word of God tells us that Jesus is the Sacrificial Lamb. In the Old Testament day after day every priest performs his religious duties again and again, offering the same sacrifices. However, when Jesus offered for all time one sacrifice for sins, he sat down at the right hand of God, see
Hebrews 10:12. Did you hear that? Jesus offered for ALL time ONE SACRIFICE for sins. Jesus is not in a wafer, he is at the right hand of the Father and in the saved.
By one sacrifice he has made perfect forever those who are being made holy, see
Hebrews 10:14. By “one sacrifice,” not a daily or weekly sacrifice of turning the wafers into the body of Christ, over and over again, by many priests all over the world.
We have been made holy through the sacrifice of the body of Jesus Christ once for all, see
Hebrews 10:10. How hard is that for anyone to understand that we have been made holy THROUGH the BODY of Jesus Christ ONCE for all?
Christ did not enter a man-made sanctuary that was only a copy of the true one; he entered heaven itself, now to appear for us in God’s presence. Nor did he enter heaven to offer himself again and again, the way the high priest enters the Most Holy Place every year with blood that is not his own. Then Christ would have had to suffer many times since the creation of the world. But now he has appeared once for all at the end of the ages to do away with sin by the sacrifice of himself, see
Hebrews 9:24-26. Jesus has appeared ONCE for ALL, not again and again in a wafer.
