Baptism in The Book of Acts

Acts 2:38 & 41 NET 
Peter said to them, “Repent, and each one of you be baptized in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit… 2:41 So those who accepted his message were baptized, and that day about three thousand people were added.

Acts 8:12-39 
12 But when they believed Philip as he was proclaiming the good news about the kingdom of God and the name of Jesus Christ, they began to be baptized, both men and women. 13 Even Simon himself believed, and after he was baptized, he stayed close to Philip constantly, and when he saw the signs and great miracles that were occurring, he was amazed.14 Now when the apostles in Jerusalem heard that Samaria had accepted the word of God, they sent Peter and John to them. 15 These two went down and prayed for them so that they would receive the Holy Spirit. 16 (For the Spirit had not yet come upon any of them, but they had only been baptized in the name of the Lord Jesus.) 17 Then Peter and John placed their hands on the Samaritans, and they received the Holy Spirit.18 Now Simon, when he saw that the Spirit was given through the laying on of the apostles’ hands, offered them money, 19 saying, “Give me this power too, so that everyone I place my hands on may receive the Holy Spirit.” 20 But Peter said to him, “May your silver perish with you, because you thought you could acquire God’s gift with money! 21 You have no share or part in this matterbecause your heart is not right before God! 22 Therefore repent of this wickedness of yours, and pray to the Lord that he may perhaps forgive you for the intent of your heart. 23 For I see that you are bitterly envious and in bondage to sin.” 24 But Simon replied, “You pray to the Lord for me so that nothing of what you have said may happen to me.” 25 So after Peter and Johnhad solemnly testified and spoken the word of the Lord, they started back to Jerusalem, proclaiming the good news to many Samaritan villages as they went.26 Then an angel of the Lord said to Philip, “Get up and go south on the road that goes down from Jerusalem to Gaza.” (This is a desert road.) 27 So he got up and went. There he met an Ethiopian eunuch, a court official of Candace, queen of the Ethiopians, who was in charge of all her treasury. He had come to Jerusalem to worship, 28 and was returning home, sitting in his chariot, reading the prophet Isaiah. 29 Then the Spirit said to Philip, “Go over and join this chariot.” 30 So Philip ran up to it and heard the man reading Isaiah the prophet. He asked him, “Do you understand what you’re reading?” 31 The man replied, “How in the world can I, unless someone guides me?” So he invited Philip to come up and sit with him. 32 Now the passage of scripture the man was reading was this:“He was led like a sheep to slaughter,and like a lamb before its shearer is silent,so he did not open his mouth.33 In humiliationjustice was taken from him.Who can describe his posterity?For his life was taken away from the earth.”34 Then the eunuch said to Philip, “Please tell me, who is the prophet saying this about – himself or someone else?” 35 So Philip started speaking, and beginning with this scriptureproclaimed the good news about Jesus to him. 36 Now as they were going along the road, they came to some water, and the eunuch said, “Look, there is water! What is to stop me from being baptized?” 38 So he ordered the chariot to stop, and both Philip and the eunuch went down into the water, and Philip baptized him. 39 Now when they came up out of the water, the Spirit of the Lord snatched Philip away, and the eunuch did not see him any more, but went on his way rejoicing.

Acts 10:36-48 
36 You know the message he sent to the people of Israel, proclaiming the good news of peace through Jesus Christ(he is Lord of all) – 37 you know what happened throughout Judea, beginning from Galilee after the baptism that John announced: 38 with respect to Jesus from Nazareth, thatGod anointed him with the Holy Spirit and with power. He went around doing good and healing all who were oppressed by the devil, because God was with him. 39 We are witnesses of all the things he did both in Judea and in Jerusalem. They killed him by hanging him on a tree, 40 but God raised him up on the third day and caused him to be seen, 41 not by all the people, but by us, the witnesses God had already chosen, who ate and drank with him after he rose from the dead. 42 He commanded us to preach to the people and to warn them that he is the one appointed by God as judge of the living and the dead. 43 About him all the prophets testify, that everyone who believes in him receives forgiveness of sins through his name.”44 While Peter was still speaking these words, the Holy Spirit fell on all those who heard the message. 45 The circumcised believers who had accompanied Peter were greatly astonished that the gift of the Holy Spirit had been poured out even on the Gentiles, 46 for they heard them speaking in tongues and praising God. Then Peter said, 47 “No one can withhold the water for these people to be baptized, who have received the Holy Spirit just as we did, can he?” 48 So he gave orders to have them baptized in the name of Jesus Christ. Then they asked him to stay for several days.

Acts 19:1-7 & Acts 22:15-16 
1 While Apollos was in Corinth, Paul went through the inland regions and came to Ephesus. He found some disciples there 2 and said to them, “Did you receive the Holy Spirit when you believed?” They replied, “No, we have not even heard that there is a Holy Spirit.” 3 So Paul said, “Into what then were you baptized?” “Into John’s baptism,” they replied. 4 Paul said, “John baptized with a baptism of repentance, telling the people to believe in the one who was to come after him, that is, in Jesus.” 5 When they heard this, they were baptized in the name of the Lord Jesus, 6 and when Paul placed his hands on them, the Holy Spirit came upon them, and they began to speak in tongues and to prophesy. 7 (Now there were about twelve men in all.)

15 because you will be his witness to all people of what you have seen and heard. 16 And now what are you waiting for? Get up, be baptized, and have your sins washed away, calling on his name.’

How long did people wait to get baptized in the early church?

Harvard University theology professor Harvey Cox indicated in his book, “Fire From Heaven”, that the only way people were ever baptized in the New Testament Church was “in the name of the Lord Jesus” rather than “in the name of the Father, Son, and Holy Spirit” - do you think this baptismal detail is important - and if so, why?

Given what Jesus said in Matthew 28:19, what should we think about how the Apostles obeyed His command in the Book of Acts?

If you’ve already been baptized as a believer, when is the last time your shared the details of your baptism with others as part of your testimony - like the Apostle Paul did in Acts 22?*
