Where to begin a necessarily short statement on the Eucharist or Mass? There could scarcely be a better place to begin than the Church's Liturgy for the Mass of the Lord' Supper on Holy Thursday. Here you will find all three readings:
First Reading: Exodus 12:1-8.11-14
The Lord said to Moses and Aaron in the land of Egypt, 'This month is to be the first of all the others for you, the first month of your year. Speak to the whole community of Israel and say, "On the tenth day of this month each man must take an animal from the flock, one for each family: one animal for each household. If the household is too small to eat the animal, a man must join with his neighbour, the nearest to his house, as the number of persons requires. You must take into account what each can eat in deciding the number for the animal. It must be an animal without blemish, a male one year old; you may take it from either sheep or goats. You must keep it till the fourteenth day of the month when the whole assembly of the community of Israel will slaughter it between the two evenings. Some of the blood must then be taken and put on the two doorposts and the lintel of the houses where it is eaten.
You shall eat it like this: with a girdle around your waste, sandals on your feet, a staff in your hand. You shall eat it hastily: it is a Passover in honour of Yahweh. That night, I will go through the land of Egypt and strike down all the first-born in the land of Egypt, man and beast alike, and I shall deal out punishment to all the gods of Egypt, I am Yahweh! The blood shall serve to mark the houses that you live in. When I see the blood I will pass over you and you shall escape the destroying plague when I strike the land of Egypt. This day is to be a day of remembrance for you, and you must celebrate it as a feast in Yahweh's honour. For all generations you are to declare it a day of festival, for ever.
The word of the Lord!
Second Reading:1 Corinthians 11:23-26
This is what I received from the Lord, and in turn passed on to you: that on the same night that he was betrayed, the Lord Jesus took some bread and thanked God for it, and broke it, and he said, 'This is my body, which is for you; do this as a memorial of me.' In the same way he took the cup after supper, and said, 'This is the new covenant in my blood. Whenever you drink it, do this as a memorial of me.' Until the Lord comes, therefore, every time you eat this bread and drink this cup, you are proclaiming his death.
The word of the Lord!
Gospel Reading: John 13:1-15
It was before the festival of the Passover, and Jesus knew that the hour had come for him to pass from this world to the Father. He had always loved those who were his in the world, but now he showed how perfect his love was.
They were at supper, and the devil had already put it into the mind of Judas Iscariot son of Simon, to betray him. Jesus knew that the Father had put everything into his hands, and that he had come from God and was returning to God, and he got up from the table, removed his outer garment and, taking a towel wrapped it round his waist; he then poured water into a basin and began to wash the disciples' feet and to wipe them away with the towel he was wearing.
He came to Simon Peter, who said to him, 'Lord, are you going to wash my feet?' Jesus answered, 'At the moment you do not know what I am doing, but later you will understand.' 'Never!' said Peter. 'You shall never wash my feet.' Jesus replied, 'If I do not wash you, you can have nothing in common with me.' 'Then, Lord,' said Peter, 'not only my feet but my hands and my head as well!' Jesus said, 'No one who has taken a bath needs washing, he is clean all over. You too are clean, though not all of you are.' He knew who was going to betray him, that was why he said, 'though not all of you here.'
When he had washed their feet and put on his clothes again he went back to the table. 'Do you understand' he said 'what I have done to you? You call me Master and Lord, and rightly; so I am. If I, then, the Lord and Master, have washed your feet, you should wash each other's feet. I have given you an example so that you may copy what I have done to you.
