First Reading: Acts 1: 1-11

1 The former treatise I made, O Theophilus, of all things which Jesus began to do and to teach,

2 Until the day on which, giving commandments by the Holy Ghost to the apostles whom he had chosen, he was taken up.

3 To whom also he shewed himself alive after his passion, by many proofs, for forty days appearing to them, and speaking of the kingdom of God.

4 And eating together with them, he commanded them, that they should not depart from Jerusalem, but should wait for the promise of the Father, which you have heard (saith he) by my mouth.

5 For John indeed baptized with water, but you shall be baptized with the Holy Ghost, not many days hence.

6 They therefore who were come together, asked him, saying: Lord, wilt thou at this time restore again the kingdom to Israel?

7 But he said to them: It is not for you to know the times or moments, which the Father hath put in his own power:

8 But you shall receive the power of the Holy Ghost coming upon you, and you shall be witnesses unto me in Jerusalem, and in all Judea, and Samaria, and even to the uttermost part of the earth.

9 And when he had said these things, while they looked on, he was raised up: and a cloud received him out of their sight.

10 And while they were beholding him going up to heaven, behold two men stood by them in white garments.

11 Who also said: Ye men of Galilee, why stand you looking up to heaven? This Jesus who is taken up from you into heaven, shall so come, as you have seen him going into heaven.

Second Reading: Ephesians 1: 17-23 or Hebrews 9: 24-28; 10: 19-23

17 That the God of our Lord Jesus Christ, the Father of glory, may give unto you the spirit of wisdom and of revelation, in the knowledge of him:

18 The eyes of your heart enlightened, that you may know what the hope is of the glory of his inheritance in the saints.

19 And what is the exceeding greatness of his power towards us, who believe according to the operation of the might of his power,

20 Which he wrought in Christ, raising him up from the dead, and setting him on his right hand in the heavenly places.

21 Above all principality, and power, and virtue, and dominion, and every name that is named, not only in this world, but also in that which is to come.

22 And he hath subjected all things under his feet, and hath made him head over all the church,

23 Which is his body, and the fulness of him who is filled all in all.

Or

24 For Jesus is not entered into the holies made with hands, the patterns of the true: but into heaven itself, that he may appear now in the presence of God for us.

25 Nor yet that he should offer himself often, as the high priest entereth into the holies, every year with the blood of others:

26 For then he ought to have suffered often from the beginning of the world: but now once at the end of ages, he hath appeared for the destruction of sin, by the sacrifice of himself.

27 And as it is appointed unto men once to die, and after this the judgment:

28 So also Christ was offered once to exhaust the sins of many; the second time he shall appear without sin to them that expect him unto salvation.

10:19 Having therefore, brethren, a confidence in the entering into the holies by the blood of Christ;

20 A new and living way which he hath dedicated for us through the veil, that is to say, his flesh,

21 And a high priest over the house of God:

22 Let us draw near with a true heart in fulness of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with clean water.

23 Let us hold fast the confession of our hope without wavering (for he is faithful that hath promised),
Alleluia: Matthew 28: 19a, 20b
R. Alleluia, alleluia.

19a, 20b Go and teach all nations, says the Lord; I am with you always, until the end of the world.

R. Alleluia, alleluia.

Gospel: Luke 24: 46-53

46 And he said to them: Thus it is written, and thus it behoved Christ to suffer, and to rise again from the dead, the third day:

47 And that penance and remission of sins should be preached in his name, unto all nations, beginning at Jerusalem.

48 And you are witnesses of these things.

49 And I send the promise of my Father upon you: but stay you in the city till you be endued with power from on high.

50 And he led them out as far as Bethania: and lifting up his hands, he blessed them.

51 And it came to pass, whilst he blessed them, he departed from them, and was carried up to heaven.

52 And they adoring went back into Jerusalem with great joy.

53 And they were always in the temple, praising and blessing God. Amen.
