First Reading Acts 1.1-11
In the first book, Theophilus, I wrote about all that Jesus did and taught from the beginning until the day when he was taken up to heaven, after giving instructions through the Holy Spirit to the Apostles whom he had chosen. After his suffering he presented himself alive to them by many convincing proofs, appearing to them during forty days and speaking about the kingdom of God.
While staying with them, he ordered them not to leave Jerusalem, but to wait there for the promise of the Father. “This,” he said, “is what you have heard from me; for John baptized with water, but you will be baptized with the Holy Spirit not many days from now.”
So when they had come together, they asked him, “Lord, is this the time when you will restore the kingdom to Israel?” He replied, “It is not for you to know the times or periods that the Father has set by his own authority. But you will receive power when the Holy Spirit has come upon you; and you will be my witnesses in Jerusalem, in all Judea and Samaria, and to the ends of the earth.”
When he had said this, as they were watching, he was lifted up, and a cloud took him out of their sight. While he was going and they were gazing up toward heaven, suddenly two men in white robes stood by them. They said, “Men of Galilee, why do you stand looking up toward heaven? This Jesus, who has been taken up from you into heaven, will come in the same way as you saw him go into heaven.”
Psalm 47
R. God has gone up with a shout, the Lord with the sound of a trumpet. or R. Alleluia!
Clap your hands, all you peoples; shout to God with loud songs of joy. For the Lord, the Most High, is awesome, a great king over all the earth. R.
God has gone up with a shout, the Lord with the sound of a trumpet. Sing praises to God, sing praises; sing praises to our King, sing praises. R.
For God is the king of all the earth; sing praises with a Psalm. God is king over the nations; God sits on his holy throne. R.

Ephesians 1.17-23
Brothers and sisters: I pray that the God of our Lord Jesus Christ, the Father of glory, may give you a spirit of wisdom and revelation as you come to know him, so that, with the eyes of your heart enlightened, you may know what is the hope to which he has called you, what are the riches of his glorious inheritance among the saints, and what is the immeasurable greatness of his power for us who believe, according to the working of his great power.
God put this power to work in Christ when he raised him from the dead and seated him at his right hand in the heavenly places, far above all rule and authority and power and dominion, and above every name that is named, not only in this age but also in the age to come.
And he has put all things under his feet and has made him the head over all things for the Church, which is his body, the fullness of him who fills all in all.

Ephesians 4.1-7, 11-13
Brothers and sisters: I, the prisoner in the Lord, beg you to lead a life worthy of the calling to which you have been called, with all humility and gentleness, with patience, bearing with one another in love, making every effort to maintain the unity of the Spirit in the bond of peace. There is one body and one Spirit, just as you were called to the one hope of your calling, one Lord, one faith, one baptism, one God and Father of all, who is above all and through all and in all. But each of us was given grace according to the measure of Christ’s gift.
The gifts he gave were that some would be Apostles, some Prophets, some evangelists, some pastors and teachers, to equip the saints for the work of ministry, for building up the body of Christ, until all of us come to the unity of the faith and of the knowledge of the Son of God, to maturity, to the measure of the full stature of Christ.
Gospel Mark 16.15-20
Jesus appeared to the eleven, and he said to them, “Go into all the world and proclaim the good news to the whole creation. The one who believes and is baptized will be saved; but the one who does not believe will be condemned. And these signs will accompany those who believe: by using my name they will cast out demons; they will speak in new tongues; they will pick up snakes in their hands, and if they drink any deadly thing, it will not hurt them; they will lay their hands on the sick, and they will recover.”
So then the Lord Jesus, after he had spoken to them, was taken up into heaven and sat down at the right hand of God. And they went out and proclaimed the good news everywhere, while the Lord worked with them and confirmed the message by the signs that accompanied it.
