First Reading

1 Samuel 3:3b-10, 19

10And the Lord came, and stood, and he called, just as he had called the other times, “Samuel, Samuel.” And Samuel said, “Speak, Lord, for your servant is listening.” 11And the Lord said to Samuel: “Behold, I am accomplishing a word in Israel. Whoever will hear about it, both his ears will ring. 12In that day, I will raise up against Eli all the things that I have spoken over his house. I will begin, and I will finish. 13For I have foretold to him that I will judge his house unto eternity, because of iniquity. For he had known that his sons acted shamefully, and he did not chastise them. 14For this reason, I have sworn to the house of Eli that the iniquity of his house will not be expiated, with victims or with gifts, even forever.” 15Then Samuel slept until morning, and he opened the doors of the house of the Lord. And Samuel was afraid to tell the vision to Eli. 16Then Eli called Samuel, and he said, “Samuel, my son?” And responding, he said, “I am here.” 17And he questioned him: “What is the word that the Lord has spoken to you? I beg you that you may not conceal it from me. May God do these things to you, and may he add these other things, if you hide from me one word out of all the things that were told to you.” 18And so, Samuel revealed to him all the words, and he did not hide them from him. And he responded: “He is the Lord. May he do what is good in his own eyes.” 19And Samuel grew up, and the Lord was with him, and not one of his words fell to the ground.
Responsorial Psalm

Psalm 39

2I have waited expectantly for the Lord, and he was attentive to me. 3And he heard my prayers and he led me out of the pit of misery and the quagmire. And he stationed my feet upon a rock, and he directed my steps. 4And he sent a new canticle into my mouth, a song to our God. Many will see, and they will fear; and they will hope in the Lord. 5Blessed is the man whose hope is in the name of the Lord, and who has no respect for vanities and absurd falsehoods. 6You have accomplished your many wonders, O Lord my God, and there is no one similar to you in your thoughts. I have announced and I have spoken: they are multiplied beyond number. 7Sacrifice and oblation, you did not want. But you have perfected ears for me. Holocaust and sin offering, you did not require. 8Then I said, “Behold, I draw near.” At the head of the book, it has been written of me: 9that I should do your will. My God, I have willed it. And your law is in the midst of my heart. 10I have announced your justice in a great Church: behold, I will not restrain my lips. O Lord, you have known it.

1 Corinthians 6:13c-15a, 17-20

17But whoever is joined to the Lord is one spirit. 18Flee from fornication. Every sin whatsoever that a man commits is outside of the body, but whoever fornicates, sins against his own body. 19Or do you not know that your bodies are the Temple of the Holy Spirit, who is in you, whom you have from God, and that you are not your own? 20For you have been bought at a great price. Glorify and carry God in your body.
Gospel

John 1:35-42

35The next day again, John was standing with two of his disciples. 36And catching sight of Jesus walking, he said, “Behold, the Lamb of God.” 37And two disciples were listening to him speaking. And they followed Jesus. 38Then Jesus, turning around and seeing them following him, said to them, “What are you seeking?” And they said to him, “Rabbi (which means in translation, Teacher), where do you live?” 39He said to them, “Come and see.” They went and saw where he was staying, and they stayed with him that day. Now it was about the tenth hour. 40And Andrew, the brother of Simon Peter, was one of the two who had heard about him from John and had followed him. 41First, he found his brother Simon, and he said to him, “We have found the Messiah,” (which is translated as the Christ). 42And he led him to Jesus. And Jesus, gazing at him, said: “You are Simon, son of Jonah. You shall be called Cephas,” (which is translated as Peter).
