Prayer of the day:  O God, on this day You once taught the hearts of Your faithful people by sending them the light of Your Holy Spirit.  Grant us in our day by the same Spirit to have a right understanding in all things and evermore to rejoice in His holy consolation; through Jesus Christ, Your Son, our Lord, who lives and reigns with You and the Holy Spirit, one God, now and forever.  Amen.

The Tower of Babel

11 Now the whole earth had one language and the same words. ² And as people migrated from the east, they found a plain in the land of Shinar and settled there. ³ And they said to one another, “Come, let us make bricks, and burn them thoroughly.” And they had brick for stone, and bitumen for mortar. ⁴ Then they said, “Come, let us build ourselves a city and a tower with its top in the heavens, and let us make a name for ourselves, lest we be dispersed over the face of the whole earth.” ⁵ And the Lord came down to see the city and the tower, which the children of man had built. ⁶ And the Lord said, “Behold, they are one people, and they have all one language, and this is only the beginning of what they will do. And nothing that they propose to do will now be impossible for them. ⁷ Come, let us go down and there confuse their language, so that they may not understand one another’s speech.” ⁸ So the Lord dispersed them from there over the face of all the earth, and they left off building the city. ⁹ Therefore its name was called Babel, because there the Lord confused the language of all the earth. And from there the Lord dispersed them over the face of all the earth.

Epistle:

Acts 2:1-21                                            

The Coming of the Holy Spirit

2 When the day of Pentecost arrived, they were all together in one place. ² And suddenly there came from heaven a sound like a mighty rushing wind, and it filled the entire house where they were sitting. ³ And divided tongues as of fire appeared to them and rested on each one of them. ⁴ And they were all filled with the Holy Spirit and began to speak in other tongues as the Spirit gave them utterance.

⁵ Now there were dwelling in Jerusalem Jews, devout men from every nation under heaven. ⁶ And at this sound the multitude came together, and they were bewildered, because each one was hearing them speak in his own language. ⁷ And they were amazed and astonished, saying, “Are not all these who are speaking Galileans? ⁸ And how is it that we hear, each of us in his own native language? ⁹ Parthians and Medes and Elamites and residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia, ¹⁰ Phrygia and Pamphylia, Egypt and the parts of Libya belonging to Cyrene, and visitors from Rome, ¹¹ both Jews and proselytes, Cretans and Arabians—we hear them telling in our own tongues the mighty works of God.” ¹² And all were amazed and perplexed, saying to one another, “What does this mean?” ¹³ But others mocking said, “They are filled with new wine.”

Peter’s Sermon at Pentecost

¹⁴ But Peter, standing with the eleven, lifted up his voice and addressed them: “Men of Judea and all who dwell in Jerusalem, let this be known to you, and give ear to my words. ¹⁵ For these people are not drunk, as you suppose, since it is only the third hour of the day. ¹⁶ But this is what was uttered through the prophet Joel:

¹⁷ “‘And in the last days it shall be, God declares,
that I will pour out my Spirit on all flesh,
and your sons and your daughters shall prophesy,
    and your young men shall see visions,
    and your old men shall dream dreams;
¹⁸ even on my male servants and female servants
    in those days I will pour out my Spirit, and they shall prophesy.
¹⁹ And I will show wonders in the heavens above
    and signs on the earth below,
    blood, and fire, and vapor of smoke;
²⁰ the sun shall be turned to darkness
    and the moon to blood,
    before the day of the Lord comes, the great and magnificent day.
²¹ And it shall come to pass that everyone who calls upon the name of the Lord shall be saved.’

Gospel:

John 17:23-31                                                                

²³ I in them and you in me, that they may become perfectly one, so that the world may know that you sent me and loved them even as you loved me. ²⁴ Father, I desire that they also, whom you have given me, may be with me where I am, to see my glory that you have given me because you loved me before the foundation of the world. ²⁵ O righteous Father, even though the world does not know you, I know you, and these know that you have sent me. ²⁶ I made known to them your name, and I will continue to make it known, that the love with which you have loved me may be in them, and I in them.”
