First Reading
Acts 4:8-12
Peter, filled with the Holy Spirit, said to them: Ye princes of the people, and ancients, hear: If we this day are examined concerning the good deed done to the infirm man, by what means he hath been made whole: Be it known to you all, and to all the people of Israel, that by the name of our Lord Jesus Christ of Nazareth, whom you crucified, whom God hath raised from the dead, even by him this man standeth here before you whole.
This is the stone which was rejected by you the builders, which is become the head of the corner. Neither is there salvation in any other.
Responsorial Psalm
Psalm 118:1, 8-9, 21-23, 26, 29
R. The stone rejected by the builders has become the cornerstone.
Give praise to the Lord, for he is good: for his mercy endureth for ever. It is good to confide in the Lord, rather than to have confidence in man.
R. The stone rejected by the builders has become the cornerstone.
I will give glory to thee because thou hast heard me: and art become my salvation. The stone which the builders rejected; the same is become the head of the corner.
R. The stone rejected by the builders has become the cornerstone.
Second Reading
1 John 3:1-2
Behold what manner of charity the Father hath bestowed upon us, that we should be called, and should be the sons of God. Therefore the world knoweth not us, because it knew not him. Dearly beloved, we are now the sons of God; and it hath not yet appeared what we shall be. We know, that, when he shall appear, we shall be like to him: because we shall see him as he is.
Holy Gospel
John 10:11-18
Jesus said: I am the good shepherd. The good shepherd giveth his life for his sheep. But the hireling, and he that is not the shepherd, whose own the sheep are not, seeth the wolf coming, and leaveth the sheep, and flieth: and the wolf catcheth, and scattereth the sheep: And the hireling flieth, because he is a hireling: and he hath no care for the sheep.
I am the good shepherd; and I know mine, and mine know me. As the Father knoweth me, and I know the Father: and I lay down my life for my sheep.
