The Second Glorious Mystery of the Rosary is Christ's Ascension into heaven!
Then Jesus approached and said to them, “All power in heaven and on earth has been given to me. Go, therefore, and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, until the end of the age.”
And it happened that, while he was with them at table, he took bread, said the blessing, broke it, and gave it to them. With that their eyes were opened and they recognized him, but he vanished from their sight. Then they said to each other, “Were not our hearts burning [within us] while he spoke to us on the way and opened the scriptures to us?” So they set out at once and returned to Jerusalem where they found gathered together the eleven and those with them who were saying, “The Lord has truly been raised and has appeared to Simon!” Then the two recounted what had taken place on the way and how he was made known to them in the breaking of the bread.
While they were still speaking about this, he stood in their midst and said to them, “Peace be with you.” But they were startled and terrified and thought that they were seeing a ghost. Then he said to them, “Why are you troubled? And why do questions arise in your hearts? Look at my hands and my feet, that it is I myself. Touch me and see, because a ghost does not have flesh and bones as you can see I have.” And as he said this, he showed them his hands and his feet. While they were still incredulous for joy and were amazed, he asked them, “Have you anything here to eat?” They gave him a piece of baked fish; he took it and ate it in front of them.
He said to them, “These are my words that I spoke to you while I was still with you, that everything written about me in the law of Moses and in the prophets and psalms must be fulfilled.” Then he opened their minds to understand the scriptures. And he said to them, “Thus it is written that the Messiah would suffer and rise from the dead on the third day and that repentance, for the forgiveness of sins, would be preached in his name to all the nations, beginning from Jerusalem. You are witnesses of these things. And [behold] I am sending the promise of my Father upon you; but stay in the city until you are clothed with power from on high.”
Then he led them [out] as far as Bethany, raised his hands, and blessed them. As he blessed them he parted from them and was taken up to heaven. They did him homage and then returned to Jerusalem with great joy, and they were continually in the temple praising God.
