First Lesson: Acts of the Apostles (Acts 2:1-21) 

When the day of Pentecost had come, they were all together in one place. And suddenly a sound came from heaven like the rush of a mighty wind, and it filled all the house where they were sitting.  And there appeared to them tongues as of fire, distributed and resting on each one of them. And they were all filled with the Holy Spirit and began to speak in other tongues, as the Spirit gave them utterance.  Now there were dwelling in Jerusalem Jews, devout men from every nation under the heaven. And at this sound the multitude came together, and they were bewildered, because each one heard them speaking in his own language. And they were amazed and wondered, saying "Are not all these who are speaking Galileans?  And how is it that we hear, each of us in his own native language? Par'thians and Medes and E'lamites residents of Mesopota'mia, Judea and Cappado'cia, Pontus and Asia, and Phryg'ia and Pamphyl'ia and Egypt and the parts of Libya belonging to Cyre'ne and visitors from Rome, both Jews and proselytes, Cretans and Arabians, we hear them telling in our own is the mighty works of God." And all were amazed and asked, saying to one another, "What does this mean?"  But others mocking said, "they are filled with new wine." But Peter, standing with the 11, 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. For these men are not drunk, as you suppose, since it is only the third hour of the day; but this is what was spoken by the prophet Joel: 'and in the last day it shall be, God declares, that I will pour out my Spirit upon all flesh, and your sons and your daughters shall prophesy and I will show wonders in heaven above and signs on earth beneath, blood, and fire, and vapor of smoke; the sun shall be turned into darkness and the moon into blood, before the day of the Lord comes, the great manifest day. And it shall be that 

whoever calls on the name of the Lord shall be saved.'

Psalm: 104:25-35, 37

25 O Lord, how manifold are your works! *
         in wisdom you have made them all; the earth is full of             your creatures.

26 Yonder is the great and wide sea
       with its living things too many to number, * creatures              both small and great.

27 There move the ships, and there is that Leviathan, *
       which you have made for the sport of it.

28 All of them look to you *
       to give them their food in due season.

29 You give it to them; they gather it; *
       you open your hand, and they are filled with good                     things.

30 You hide your face, and they are terrified; *
       you take away their breath, and they die and return to           their dust.

31 You send forth your Spirit, and they are created; *
       and so you renew the face of the earth.

32 May the glory of the Lord endure forever; *
       may the Lord rejoice in all his works.

33 He looks at the earth and it trembles; *
       he touches the mountains and they smoke.

34 I will sing to the Lord as long as I live; *
       I will praise my God while I have my being.

35 May these words of mine please him; *
       I will rejoice in the Lord.

37 Bless the Lord, O my soul. *
       Hallelujah!

Second Lesson: 1 Corinthians (12:3b-13)

Therefore, I want you to understand that no one speaking by the Spirit of God ever says “Jesus be cursed!” and no one can say “Jesus is Lord” except by the Holy Spirit.

Now there are varieties of gifts, but the same Spirit; and there are varieties of service, but the same Lord; and there are varieties of working, but it is the same God who inspires them all in everyone. To each is given the manifestation of the Spirit for the common good. To one is given through the Spirit the utterance of wisdom, and to another the utterance of knowledge according to the same Spirit, to another faith by the same Spirit, to another gifts of healing by the one Spirit, to another the working of miracles, to another prophecy, to another the ability to distinguish between spirits, to another various kinds of tongues, to another the interpretation of tongues. All these are inspired by one and the same Spirit, who apportions to each one individually as he wills. For just as the body is one and has many members, and all the members of the body, though many, are one body, so it is with Christ. For by one Spirit we were all baptized into one body—Jews or Greeks, slaves or free—and all were made to drink of one Spirit. On the evening of that day, the first day of the week, the doors being shut where the disciples were, for fear of the Jews, Jesus came and stood among them and said to them, “Peace be with you.” When he had said this, he showed them his hands and his side. Then the disciples were glad when they saw the Lord. Jesus said to them again, “Peace be with you. As the Father has sent me, even so I send you.” And when he had said this, he breathed on them, and said to them, “Receive the Holy Spirit. If you forgive the sins of any, they are forgiven; if you retain the sins of any, they are retained.”

The Holy Gospel

John 20:19-23

On the evening of that day, the first day of the week, the doors being shut where the disciples were, for fear of the Jews, Jesus came and stood among them and said to them, “Peace be with you.” When he had said this, he showed them his hands and his side. Then the disciples were glad when they saw the Lord. Jesus said to them again, “Peace be with you. As the Father has sent me, even so I send you.” And when he had said this, he breathed on them, and said to them, “Receive the Holy Spirit. If you forgive the sins of any, they are forgiven; if you retain the sins of any, they are retained.”
