Jesus gave His followers bread and wine and asked them simply, "To Remember". What do we remember when we eat this bread and drink from this cup?
Matthew 26:26-30 (TLB): As they were eating, Jesus took a small loaf of bread and blessed it and broke it apart and gave it to the disciples and said, “Take it and eat it, for this is my body.” And he took a cup of wine and gave thanks for it and gave it to them and said, “Each one drink from it, 28 for this is my blood, sealing the new covenant. It is poured out to forgive the sins of multitudes. 29 Mark my words—I will not drink this wine again until the day I drink it new with you in my Father’s Kingdom.” And when they had sung a hymn, they went out to the Mount of Olives.
Mark 14:22-26 (TLB): As they were eating, Jesus took bread and asked God’s blessing on it and broke it in pieces and gave it to them and said, “Eat it—this is my body.” Then he took a cup of wine and gave thanks to God for it and gave it to them; and they all drank from it. And he said to them, “This is my blood, poured out for many, sealing the new agreement[a] between God and man. I solemnly declare that I shall never again taste wine until the day I drink a different kind in the Kingdom of God.” Then they sang a hymn and went out to the Mount of Olives.
Luke 22:14-20 (TLB): Then Jesus and the others arrived, and at the proper time all sat down together at the table; and he said, “I have looked forward to this hour with deep longing, anxious to eat this Passover meal with you before my suffering begins. For I tell you now that I won’t eat it again until what it represents has occurred in the Kingdom of God.” Then he took a glass of wine, and when he had given thanks for it, he said, “Take this and share it among yourselves. For I will not drink wine again until the Kingdom of God has come.” Then he took a loaf of bread; and when he had thanked God for it, he broke it apart and gave it to them, saying, “This is my body, given for you. Eat it in remembrance of me.” After supper he gave them another glass of wine, saying, “This wine is the token of God’s new agreement to save you—an agreement sealed with the blood I shall pour out to purchase back your souls.
John 13:3-17 (TLB): Jesus knew that the Father had given him everything and that he had come from God and would return to God. And how he loved his disciples! So he got up from the supper table, took off his robe, wrapped a towel around his loins, poured water into a basin, and began to wash the disciples’ feet and to wipe them with the towel he had around him. When he came to Simon Peter, Peter said to him, “Master, you shouldn’t be washing our feet like this!” Jesus replied, “You don’t understand now why I am doing it; some day you will.” “No,” Peter protested, “you shall never wash my feet!" “But if I don’t, you can’t be my partner,” Jesus replied. Simon Peter exclaimed, “Then wash my hands and head as well—not just my feet!” Jesus replied, “One who has bathed all over needs only to have his feet washed to be entirely clean. Now you are clean—but that isn’t true of everyone here.” For Jesus knew who would betray him. That is what he meant when he said, “Not all of you are clean.” After washing their feet he put on his robe again and sat down and asked, “Do you understand what I was doing? You call me ‘Master’ and ‘Lord,’ and you do well to say it, for it is true. And since I, the Lord and Teacher, have washed your feet, you ought to wash each other’s feet. I have given you an example to follow: do as I have done to you. How true it is that a servant is not greater than his master. Nor is the messenger more important than the one who sends him. You know these things—now do them! That is the path of blessing!
