I am not implying that every regeneration ends with Speaking in Tongues. But Paul said anyone can have the Gift so it makes perfect sense why it does happen but many times during Salvation.
Some help for the uninformed:
Vine's Expository Dictionary of New Testament Words: NAME [ A-1,Noun,G3686, onoma ]
(II) for all that a "name" implies, of authority, character, rank, majesty, power, excellence, etc., of everything that the "name" covers:
(a) of the "Name" of God as expressing His attributes, etc., e.g., Matthew 6:9; Luke 1:49; John 12:28; John 17:6, John 17:26; Romans 15:9; 1 Timothy 6:1; Hebrews 13:15; Revelation 13:6;
(b) of the "Name" of Christ, e.g., Matthew 10:22; Matthew 19:29; John 1:12; John 2:23; John 3:18; Acts 26:9; Romans 1:5; James 2:7; 1 John 3:23; 3 John 1:7; Revelation 2:13; Revelation 3:8; also the phrases rendered "in the name;" these may be analyzed as follows:
(1) representing the authority of Christ, e.g., Matthew 18:5 (with epi, "on the ground of My authority"); so Matthew 24:5 (falsely) and parallel passages; as substantiated by the Father, John 14:26; John 16:23 (last clause), RV;
(2) in the power of (with en, "in"), e.g., Mark 16:17; Luke 10:17; Acts 3:6; Acts 4:10; Acts 16:18; James 5:14;
(3) in acknowledgement or confession of, e.g., Acts 4:12; Acts 8:16; Acts 9:27-Acts 9:28;
(4) in recognition of the authority of (sometimes combined with the thought of relying or resting on), Matthew 18:20; cp. Matthew 28:19; Acts 8:16; Acts 9:2 (eis, "into"); John 14:13; John 15:16; Ephesians 5:20; Colossians 3:17;
(5) owing to the fact that one is called by Christ's "Name" or is identified with Him, e.g. 1 Peter 4:14 (with en, "in"); with heneken, "for the sake of," e.g., Matthew 19:29; with dia, "on account of," Matthew 10:22; Matthew 24:9; Mark 13:13; Luke 21:17; John 15:21; 1 John 2:12; Revelation 2:3
(MY NOTE: In the name of invokes: authority, power, representation, commission, on behalf of. The definition never infers "Say These Exact Words"!
Examples: Stop in the name of the law doesn’t mean: "The cop has to say those exact words" & "I come in my father’s name" doesn’t mean to "literally say his name out loud."
"In the name of Jesus" = by His authority, not a spoken formula
Jesus Himself declares His total authority:
Matt 28:18 Jesus said; All authority in heaven & on earth has been given to Me.
This is the foundation. If He has all authority, then "acting in His name" means acting under that authority.
Phil 2:9–10 God gave Him "the name above every name". - This is not about syllables, it’s about authority, status, rank, dominion.
Lk 10:17 Even the demons are subject to us in Your name. - They weren't invoking a formula. They were operating under His authority.
Acts 3:16 "His name, "by faith in His name" has made this man strong." - Peter explicitly says the power came from Jesus’ authority, not from reciting an exact phrase.
Eph 1:20–22 Christ is seated "far above all rule and authority and power & dominion. - A cosmic declaration of Jesus authority.
Jn 5:27 The Father "gave Him authority to execute judgment."
Jn 10:18 "I have authority to lay down My life" & "the authority to take it up again."
Col 3:17 “Whatever you do, do all in the name of the Lord Jesus." - If say these exact words (in the name of Jesus) is taken literally. Then every meal, prayer & conversation would require this spoken formula.
Scripture repeatedly teaches that Jesus’ name refers to His authority, not a spoken formula. Acting "in His name" meant acting under His divine authority. Exactly how the apostles healed, cast out demons, preached & baptized.
Acts 2:38 Be baptized "in the name of Jesus Christ" = Identify with Jesus as Messiah, not John the Baptist or Judaism. This is about allegiance & authority, not a verbal formula. If it were a formula, it would contradict Jesus’ own command in Matthew 28:19.
Acts 3:6 In the name of Jesus Christ of Nazareth, rise up and walk. - Peter invokes Jesus’ "authority" not a magic phrase. Proof: Peter later explains the healing came by faith in His name (Acts 3:16), not by reciting exact syllables.
Acts 4:7 "By what power or by what name have you done this"- The Sanhedrin is asking: "Under whose authority did you do this". They are not asking, What exact words did you say?
Acts 4:10 By the name of Jesus Christ, this man stands before you whole. - Again, authority, not formula. Peter is explaining the source of power, not the words he spoke.
Acts 8:12 They were baptized, "in the name of Jesus Christ" - They were baptized into allegiance to Jesus, not Simon the sorcerer or Judaism or Rome etc. This is identity, not incantation.
Acts 9:27 He preached boldly in the name of Jesus. - Paul preached under Jesus’ authority. He did not walk around saying "in the name of Jesus" before every sentence.
Acts 10:48 He commanded them to be baptized in the name of the Lord. - Baptized into the Lord’s authority, not a spoken formula.
Acts 15:14 God visited the Gentiles to take out a people for His name. - A people belonging to His authority, His identity.
Acts 16:18 I command you in the name of Jesus Christ to come out. - Paul invokes Jesus’ authority over demons. Proof this is not a formula: The seven sons of Sceva said the name but had no authority & the demon beat them bloody.
In the name of Jesus” in Acts 2:38. = Be baptized under the authority of Jesus the Messiah. not John, not Judaism, not Rome. It’s allegiance, not incantation.
This is what the apostles always did in Acts:
healing in His name ============ by His authority
casting out demons in His name = by His authority
preaching in His name ========== under His authority
suffering for His name ========== allegiance to His authority
baptizing in His name ========== identifying with His authority
Peter didn’t replace Jesus’ baptismal wording. He explained its authority. Jesus gave the words in Matthew 28:19. Acts gives the meaning of those words. In the name of Jesus is not a formula to recite. It’s cites the authority behind the act. If he gave a formula, it would contradict Jesus’ own command in Matthew 28:19.
