First reading: Acts of the Apostles 2:14, 36-41

On the day of Pentecost Peter stood up with the Eleven and addressed the crowd in a loud voice: ‘The whole House of Israel can be certain that God has made this Jesus whom you crucified both Lord and Christ.’

Hearing this, they were cut to the heart and said to Peter and the apostles, ‘What must we do, brothers?’ ‘You must repent,’ Peter answered ‘and every one of you must be baptised in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit. The promise that was made is for you and your children, and for all those who are far away, for all those whom the Lord our God will call to himself.’ He spoke to them for a long time using many arguments, and he urged them, ‘Save yourselves from this perverse generation.’ They were convinced by his arguments, and they accepted what he said and were baptised. That very day about three thousand were added to their number.
