First Reading: Exodus 24: 3-8
3 So Moses came and told the people all the words of the Lord, and all the judgments: and all the people answered with one voice: We will do all the words of the Lord, which he hath spoken.
4 And Moses wrote all the words of the Lord: and rising in the morning he built an altar at the foot of the mount, and twelve titles according to the twelve tribes of Israel.
5 And he sent young men of the children of Israel, and they offered holocausts, and sacrificed pacific victims of calves to the Lord.
6 Then Moses took half of the blood, and put it into bowls: and the rest he poured upon the altar.
7 And taking the book of the covenant, he read it in the hearing of the people: and they said: All things that the Lord hath spoken we will do, we will be obedient.
8 And he took the blood and sprinkled it upon the people, and he said: This is the blood of the covenant which the Lord hath made with you concerning all these words.
Responsorial Psalm: Psalms 116: 12-13, 15-16, 17-18 (13)
12 What shall I render to the Lord, for all the things he hath rendered unto me?
13 I will take the chalice of salvation; and I will call upon the name of the Lord.
15 Precious in the sight of the Lord is the death of his saints.
16 O Lord, for I am thy servant: I am thy servant, and the son of thy handmaid. Thou hast broken my bonds:
17 I will sacrifice to thee the sacrifice of praise, and I will call upon the name of the Lord.
18 I will pay my vows to the Lord in the sight of all his people:
(13 I will take the chalice of salvation; and I will call upon the name of the Lord.)
Second Reading: Hebrews 9: 11-15
11 But Christ, being come an high priest of the good things to come, by a greater and more perfect tabernacle not made with hand, that is, not of this creation:
12 Neither by the blood of goats, or of calves, but by his own blood, entered once into the holies, having obtained eternal redemption.
13 For if the blood of goats and of oxen, and the ashes of an heifer being sprinkled, sanctify such as are defiled, to the cleansing of the flesh:
14 How much more shall the blood of Christ, who by the Holy Ghost offered himself unspotted unto God, cleanse our conscience from dead works, to serve the living God?
15 And therefore he is the mediator of the new testament: that by means of his death, for the redemption of those transgressions, which were under the former testament, they that are called may receive the promise of eternal inheritance.
Gospel: Mark 14: 12-16, 22-26
12 Now on the first day of the unleavened bread, when they sacrificed the pasch, the disciples say to him: Whither wilt thou that we go, and prepare for thee to eat the pasch?
13 And he sendeth two of his disciples, and saith to them: Go ye into the city; and there shall meet you a man carrying a pitcher of water, follow him;
14 And whithersoever he shall go in, say to the master of the house, The master saith, Where is my refectory, where I may eat the pasch with my disciples?
15 And he will shew you a large dining room furnished; and there prepare ye for us.
16 And his disciples went their way, and came into the city; and they found as he had told them, and they prepared the pasch.
22 And whilst they were eating, Jesus took bread; and blessing, broke, and gave to them, and said: Take ye. This is my body.
23 And having taken the chalice, giving thanks, he gave it to them. And they all drank of it.
24 And he said to them: This is my blood of the new testament, which shall be shed for many.
25 Amen I say to you, that I will drink no more of the fruit of the vine, until that day when I shall drink it new in the kingdom of God.
26 And when they had said an hymn, they went forth to the mount of Olives.
