First Reading: Acts 2:36-41

³⁶ Let all the house of Israel therefore know assuredly that God has made him both Lord and Christ, this Jesus whom you crucified.”
³⁷ Now when they heard this they were cut to the heart, and said to Peter and the rest of the apostles, “Brethren, what shall we do?”
³⁸ And Peter said to them, “Repent, and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins; and you shall receive the gift of the Holy Spirit.
³⁹ For the promise is to you and to your children and to all that are far off, every one whom the Lord our God calls to him.”
⁴⁰ And he testified with many other words and exhorted them, saying, “Save yourselves from this crooked generation.”
⁴¹ So those who received his word were baptized, and there were added that day about three thousand souls.
