Acts 1:1-9

Revised Standard Version Catholic Edition

The Promise of the Holy Spirit

1 In the first book,^[a] O Theoph′ilus, I have dealt with all that Jesus began to do and teach, ² until the day when he was taken up, after he had given commandment through the Holy Spirit to the apostles whom he had chosen. ³ To them he presented himself alive after his passion by many proofs, appearing to them during forty days, and speaking of the kingdom of God. ⁴ And while staying^[b] with them he charged them not to depart from Jerusalem, but to wait for the promise of the Father, which, he said, “you heard from me, ⁵ for John baptized with water, but before many days you shall be baptized with the Holy Spirit.”

The Ascension of Jesus

⁶ So when they had come together, they asked him, “Lord, will you at this time restore the kingdom to Israel?” ⁷ He said to them, “It is not for you to know times or seasons which the Father has fixed by his own authority. ⁸ But you shall receive power when the Holy Spirit has come upon you; and you shall be my witnesses in Jerusalem and in all Judea and Samar′ia and to the end of the earth.” ⁹ And when he had said this, as they were looking on, he was lifted up, and a cloud took him out of their sight.
