First Reading

Acts 4:32-35

32Then the multitude of believers were of one heart and one soul. Neither did anyone say that any of the things that he possessed were his own, but all things were common to them. 33And with great power, the Apostles were rendering testimony to the Resurrection of Jesus Christ our Lord. And great grace was in them all. 34And neither was anyone among them in need. For as many as were owners of fields or houses, selling these, were bringing the proceeds of the things that they were selling, 35and were placing it before the feet of the Apostles. Then it was divided to each one, just as he had need.
Responsorial Psalm

Psalm 117

2Let Israel now say: For he is good, for his mercy is forever. 3Let the house of Aaron now say: For his mercy is forever. 4Let those who fear the Lord now say: For his mercy is forever. 5In my tribulation, I called upon the Lord. And the Lord heeded me with generosity. 6The Lord is my helper. I will not fear what man can do to me. 7The Lord is my helper. And I will look down upon my enemies. 8It is good to trust in the Lord, rather than to trust in man. 9It is good to hope in the Lord, rather than to hope in leaders. 10All the nations have surrounded me. And, in the name of the Lord, I have been avenged over them. 11Surrounding me, they closed in on me. And, in the name of the Lord, I have been avenged over them. 12They surrounded me like a swarm, and they burned like fire among the thorns. And, in the name of the Lord, I have been avenged over them. 13Having been pushed, I was overturned so as to fall. But the Lord took me up. 14The Lord is my strength and my praise. And he has become my salvation. 15A voice of exultation and salvation is in the tabernacles of the just. 16The right hand of the Lord has wrought virtue. The right hand of the Lord has exalted me. The right hand of the Lord has wrought virtue. 17I will not die, but I will live. And I will declare the works of the Lord. 18When chastising, the Lord chastised me. But he has not delivered me over to death. 19Open the gates of justice to me. I will enter them, and I will confess to the Lord. 20This is the gate of the Lord. The just will enter by it. 21I will confess to you because you have heard me. And you have become my salvation. 22The stone which the builders have rejected, this has become the head of the corner. 23By the Lord has this been done, and it is a wonder before our eyes. 24This is the day that the Lord has made. Let us exult and rejoice in it.

1 John 5:1-6

1Everyone who believes that Jesus is the Christ, is born of God. And everyone who loves God, who provides that birth, also loves him who has been born of God. 2In this way, we know that we love those born of God: when we love God and do his commandments. 3For this is the love of God: that we keep his commandments. And his commandments are not heavy. 4For all that is born of God overcomes the world. And this is the victory that overcomes the world: our faith. 5Who is it that overcomes the world? Only he who believes that Jesus is the Son of God! 6This is the One who came by water and blood: Jesus Christ. Not by water only, but by water and blood. And the Spirit is the One who testifies that the Christ is the Truth.
Gospel

John 20:19-31

19Then, when it was late on the same day, on the first of the Sabbaths, and the doors were closed where the disciples were gathered, for fear of the Jews, Jesus came and stood in their midst, and he said to them: “Peace to you.” 20And when he had said this, he showed them his hands and side. And the disciples were gladdened when they saw the Lord. 21Therefore, he said to them again: “Peace to you. As the Father has sent me, so I send you.” 22When he had said this, he breathed on them. And he said to them: “Receive the Holy Spirit. 23Those whose sins you shall forgive, they are forgiven them, and those whose sins you shall retain, they are retained.” 24Now Thomas, one of the twelve, who is called the Twin, was not with them when Jesus arrived. 25Therefore, the other disciples said to him, “We have seen the Lord.” But he said to them, “Unless I will see in his hands the mark of the nails and place my finger into the place of the nails, and place my hand into his side, I will not believe.” 26And after eight days, again his disciples were within, and Thomas was with them. Jesus arrived, though the doors had been closed, and he stood in their midst and said, “Peace to you.” 27Next, he said to Thomas: “Look at my hands, and place your finger here; and bring your hand close, and place it at my side. And do not choose to be unbelieving, but faithful.” 28Thomas responded and said to him, “My Lord and my God.” 29Jesus said to him: “You have seen me, Thomas, so you have believed. Blessed are those who have not seen and yet have believed.” 30Jesus also accomplished many other signs in the sight of his disciples. These have not been written in this book. 31But these things have been written, so that you may believe that Jesus is the Christ, the Son of God, and so that, in believing, you may have life in his name.
