First Reading: Acts 4:5-12
Peter and John had been arrested the previous day because they were proclaiming the news of the resurrection to the people. In today’s reading, Peter is filled with the Holy Spirit so that he can proclaim salvation in Jesus’ name to the religious authorities.
5The next day [the] rulers, elders, and scribes assembled in Jerusalem, 6with Annas the high priest, Caiaphas, John, and Alexander, and all who were of the high-priestly family. 7When they had made the prisoners stand in their midst, they inquired, “By what power or by what name did you do this?” 8Then Peter, filled with the Holy Spirit, said to them, “Rulers of the people and elders, 9if we are questioned today because of a good deed done to someone who was sick and are asked how this man has been healed, 10let it be known to all of you, and to all the people of Israel, that this man is standing before you in good health by the name of Jesus Christ of Nazareth, whom you crucified, whom God raised from the dead. 11This Jesus is
 ‘the stone that was rejected by you, the builders;
  it has become the cornerstone.’
12There is salvation in no one else, for there is no other name under heaven given among mortals by which we must be saved.”
Psalm: Psalm 23
The Lord is my shepherd; I shall not be in want. (Ps. 23:1)
 1The Lord | is my shepherd;
  I shall not | be in want.
 2The Lord makes me lie down | in green pastures
  and leads me be- | side still waters.
 3You restore my | soul, O Lord,
  and guide me along right pathways | for your name’s sake.
 4Though I walk through the valley of the shadow of death, I shall | fear no evil;
  for you are with me; your rod and your staff, they | comfort me. R
 5You prepare a table before me in the presence | of my enemies;
  you anoint my head with oil, and my cup is | running over.
 6Surely goodness and mercy shall follow me all the days | of my life,
  and I will dwell in the house of the | Lord forever. R
Second Reading: 1 John 3:16-24
Jesus’ death on our behalf is the clearest demonstration of divine love. This is the very love we share with others, not just through our words but especially through our deeds. In sharing such love we fulfill God’s commandments.
16We know love by this, that [Jesus Christ] laid down his life for us—and we ought to lay down our lives for one another. 17How does God’s love abide in anyone who has the world’s goods and sees a brother or sister in need and yet refuses help?
 18Little children, let us love, not in word or speech, but in truth and action. 19And by this we will know that we are from the truth and will reassure our hearts before him 20whenever our hearts condemn us; for God is greater than our hearts, and he knows everything. 21Beloved, if our hearts do not condemn us, we have boldness before God; 22and we receive from him whatever we ask, because we obey his commandments and do what pleases him.
 23And this is his commandment, that we should believe in the name of his Son Jesus Christ and love one another, just as he has commanded us. 24All who obey his commandments abide in him, and he abides in them. And by this we know that he abides in us, by the Spirit that he has given us.
Gospel: John 10:11-18
In language that recalls the twenty-third psalm, Jesus describes himself as the shepherd who cares for his sheep. He is willing to die for them, and he is able to overcome death for them.
[Jesus said:] 11“I am the good shepherd. The good shepherd lays down his life for the sheep. 12The hired hand, who is not the shepherd and does not own the sheep, sees the wolf coming and leaves the sheep and runs away—and the wolf snatches them and scatters them. 13The hired hand runs away because a hired hand does not care for the sheep. 14I am the good shepherd. I know my own and my own know me, 15just as the Father knows me and I know the Father. And I lay down my life for the sheep. 16I have other sheep that do not belong to this fold. I must bring them also, and they will listen to my voice. So there will be one flock, one shepherd. 17For this reason the Father loves me, because I lay down my life in order to take it up again. 18No one takes it from me, but I lay it down of my own accord. I have power to lay it down, and I have power to take it up again. I have received this command from my Father.”
