First Reading: Acts of the Apostles 1:15-17, 20-26
15 In those days Peter rising up in the midst of the brethren, said: (now the number of persons together was about an hundred and twenty:)
16 Men, brethren, the scripture must needs be fulfilled, which the Holy Ghost spoke before by the mouth of David concerning Judas, who was the leader of them that apprehended Jesus:
17 Who was numbered with us, and had obtained part of this ministry.
20 For it is written in the book of Psalms: Let their habitation become desolate, and let there be none to dwell therein. And his bishopric let another take.
21 Wherefore of these men who have companied with us all the time that the Lord Jesus came in and went out among us,
22 Beginning from the baptism of John, until the day wherein he was taken up from us, one of these must be made a witness with us of his resurrection.
23 And they appointed two, Joseph, called Barsabas, who was surnamed Justus, and Matthias.
24 And praying, they said: Thou, Lord, who knowest the hearts of all men, shew whether of these two thou hast chosen,
25 To take the place of this ministry and apostleship, from which Judas hath by transgression fallen, that he might go to his own place.
26 And they gave them lots, and the lot fell upon Matthias, and he was numbered with the eleven apostles.
Psalm: Psalms 113:1-2, 3-4, 5-6, 7-8
1 Praise the Lord, ye children: praise ye the name of the Lord.
2 Blessed be the name of the Lord, from henceforth now and for ever.
3 From the rising of the sun unto the going down of the same, the name of the Lord is worthy of praise.
4 The Lord is high above all nations; and his glory above the heavens.
5 Who is as the Lord our God, who dwelleth on high:
6 And looketh down on the low things in heaven and in earth?
7 Raising up the needy from the earth, and lifting up the poor out of the dunghill:
8 That he may place him with princes, with the princes of his people.
Gospel: John 15:9-17
9 As the Father hath loved me, I also have loved you. Abide in my love.
10 If you keep my commandments, you shall abide in my love; as I also have kept my Father's commandments, and do abide in his love.
11 These things I have spoken to you, that my joy may be in you, and your joy may be filled.
12 This is my commandment, that you love one another, as I have loved you.
13 Greater love than this no man hath, that a man lay down his life for his friends.
14 are my friends, if you do the things that I command you.
15 I will not now call you servants: for the servant knoweth not what his lord doth. But I have called you friends: because all things whatsoever I have heard of my Father, I have made known to you.
16 You have not chosen me: but I have chosen you; and have appointed you, that you should go, and should bring forth fruit; and your fruit should remain: that whatsoever you shall ask of the Father in my name, he may give it you.
17 These things I command you, that you love one another.
