Today, Holy Thursday, we celebrate the Mass of the Lord’s Supper, and the Institution of the Holy Eucharist—the Fifth Luminous Mystery of the Holy Rosary. When Jesus and his disciples gathered in the Upper Room on the eve of His Passion, many things occurred. The Lord washed the feet of His disciples, calling them “friends.” He predicted betrayal on the part of Peter. He let Judas know that he was aware of his treachery. He reminded them about love: 34"A new command I give you: Love one another. As I have loved you, so you must love one another. 35By this all men will know that you are my disciples, if you love one another." (John 13: 34-35). He celebrated the Passover in their presence.
22While they were eating, Jesus took bread, gave thanks and broke it, and gave it to his disciples, saying, "Take it; this is my body."
23Then he took the cup, gave thanks and offered it to them, and they all drank from it.
24"This is my blood of the covenant, which is poured out for many," he said to them. 25"I tell you the truth, I will not drink again of the fruit of the vine until that day when I drink it anew in the kingdom of God." (Mark 14: 22-25)
35Then Jesus declared, "I am the bread of life. He who comes to me will never go hungry, and he who believes in me will never be thirsty. 36But as I told you, you have seen me and still you do not believe. 37All that the Father gives me will come to me, and whoever comes to me I will never drive away. 38For I have come down from heaven not to do my will but to do the will of him who sent me. 39And this is the will of him who sent me, that I shall lose none of all that he has given me, but raise them up at the last day. 40For my Father's will is that everyone who looks to the Son and believes in him shall have eternal life, and I will raise him up at the last day."
But secondly, we all became the Body of Christ. By partaking in the Eucharist, we “acknowledge the body” as Saint Paul wrote to the Corinthians:
27Therefore, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord. 28A man ought to examine himself before he eats of the bread and drinks of the cup. 29For anyone who eats and drinks without recognizing the body of the Lord eats and drinks judgment on himself. (1 Corinthians 11: 27-29)
