1 Corinthians 14.6-19 (Epistle)

6But now, brothers, if I come to you speaking with other languages, what would I profit you unless I speak to you either by way of revelation, or of knowledge, or of prophesying, or of teaching? 7Even lifeless things that make a sound, whether pipe or harp, if they didn’t give a distinction in the sounds, how would it be known what is piped or harped? 8For if the trumpet gave an uncertain sound, who would prepare himself for war? 9So also you, unless you uttered by the tongue words easy to understand, how would it be known what is spoken? For you would be speaking into the air. 10There are, it may be, so many kinds of languages in the world, and none of them is without meaning. 11If then I don’t know the meaning of the language, I would be to him who speaks a foreigner, and he who speaks would be a foreigner to me. 12So also you, since you are zealous for spiritual gifts, seek that you may abound to the building up of the assembly.

13Therefore let him who speaks in another language pray that he may interpret. 14For if I pray in another language, my spirit prays, but my understanding is unfruitful.

15What should I do? I will pray with the spirit, and I will pray with the understanding also. I will sing with the spirit, and I will sing with the understanding also. 16Otherwise, if you bless with the spirit, how will he who fills the place of the unlearned say the “Amen” at your giving of thanks, seeing he doesn’t know what you say? 17For you most certainly give thanks well, but the other person is not built up. 18I thank my God, I speak with other languages more than you all. 19However, in the assembly I would rather speak five words with my understanding, that I might instruct others also, than ten thousand words in another language.

Acts 1.12-17, 21-26 (Epistle, St Matthias)

12Then they returned to Jerusalem from the mountain called Olivet, which is near Jerusalem, a Sabbath day’s journey away. 13When they had come in, they went up into the upper room where they were staying, that is Peter, John, James, Andrew, Philip, Thomas, Bartholomew, Matthew, James the son of Alphaeus, Simon the Zealot, and Judas the son of James. 14All these with one accord continued steadfastly in prayer and supplication, along with the women and Mary the mother of Jesus, and with his brothers.

15In these days, Peter stood up in the middle of the disciples (and the number of names was about one hundred twenty), and said, 16“Brothers, it was necessary that this Scripture should be fulfilled, which the Holy Spirit spoke before by the mouth of David concerning Judas, who was guide to those who took Jesus. 17For he was counted with us, and received his portion in this ministry.

21“Of the men therefore who have accompanied us all the time that the Lord Jesus went in and out among us, 22beginning from the baptism of John to the day that he was received up from us, of these one must become a witness with us of his resurrection.”

23They put forward two: Joseph called Barsabbas, who was also called Justus, and Matthias. 24They prayed and said, “You, Lord, who know the hearts of all men, show which one of these two you have chosen 25to take part in this ministry and apostleship from which Judas fell away, that he might go to his own place.” 26They drew lots for them, and the lot fell on Matthias; and he was counted with the eleven apostles.

Matthew 20.17-28 (Gospel)

17As Jesus was going up to Jerusalem, he took the twelve disciples aside, and on the way he said to them, 18“Behold, we are going up to Jerusalem, and the Son of Man will be delivered to the chief priests and scribes, and they will condemn him to death, 19and will hand him over to the Gentiles to mock, to scourge, and to crucify; and the third day he will be raised up.”

20Then the mother of the sons of Zebedee came to him with her sons, kneeling and asking a certain thing of him.

21He said to her, “What do you want?” She said to him, “Command that these, my two sons, may sit, one on your right hand and one on your left hand, in your Kingdom.”

22But Jesus answered, “You don’t know what you are asking. Are you able to drink the cup that I am about to drink, and be baptized with the baptism that I am baptized with?” They said to him, “We are able.”

23He said to them, “You will indeed drink my cup, and be baptized with the baptism that I am baptized with; but to sit on my right hand and on my left hand is not mine to give, but it is for whom it has been prepared by my Father.”

24When the ten heard it, they were indignant with the two brothers.

25But Jesus summoned them, and said, “You know that the rulers of the nations lord it over them, and their great ones exercise authority over them. 26It shall not be so among you; but whoever desires to become great among you shall be your servant. 27Whoever desires to be first among you shall be your bondservant, 28even as the Son of Man came not to be served, but to serve, and to give his life as a ransom for many.”
