There is not one scripture to support what you are saying~or, what those you are quoting are saying.This makes it really clear:
The baptism of the Holy Spirit may be defined as that work whereby the Spirit of God places the believer into union with Christ and into union with other believers in the body of Christ at the moment of salvation.
Election of grace placed us in Christ from the foundation of the world~or, from eternity.
2nd Timothy 1:9
“Who hath saved us, and called us with an holy calling, not according to our works, but according to his own purpose and grace, which was given us in Christ Jesus before the world began,”
Every elect child of God was placed in Christ from all eternity, and will be throughout eternity.Ephesians 1:4
“According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love:”
You are using the word salvation in a very limited sense~But, be as it may be, you truly have not one verse of scripture to support what you are attempting to say. While we agree that when a person is converted from the error of his ways, at that point, he begins to have fellowship with other believers, once they are convinced there's true conversion~almost 100% of the time, this takes place immediately. But, there is no so-called baptism of the Spirit, at least not in the sense in which the word of God uses the phrase~certainly not in the sense in which you are attempting to convey.into union with other believers in the body of Christ at the moment of salvation.
Redeemed, The baptism John spoke of is the baptism of fire, which will take place when God cast the wicked into the lake of fire~it is a baptism of judgment, not a baptism for power, or a baptism placing one into the body of Christ. Please consider carefully:The baptism of the Holy Spirit was predicted by John the Baptist (Mark 1:8)
Baptism with the Holy Ghost (here in Matthew) is a baptism of judgement with the end result to be cast into the lake of fire! This is a baptism that the wicked shall be baptized with.Matthew 3:7-11~"But when he saw many of the Pharisees and Sadducees come to his baptism, he said unto them, O generation of vipers, who hath warned you to flee from the wrath to come? Bring forth therefore fruits meet for repentance: And think not to say within yourselves, We have Abraham to our father: for I say unto you, that God is able of these stones to raise up children unto Abraham. And now also the axe is laid unto the root of the trees: therefore every tree which bringeth not forth good fruit is hewn down, and cast into the fire. I indeed baptize you with water unto repentance: but he that cometh after me is mightier than I, whose shoes I am not worthy to bear: he shall baptize you with the Holy Ghost, and with fire: Whose fan is in his hand, and he will throughly purge his floor, and gather his wheat into the garner; but he will burn up the chaff with unquenchable fire."
This is another baptism, that took place in the Acts of the apostles during the times of reformation going from the OT into the worship of the NT under Jesus Christ.“For John baptized with water, but in a few days you will be baptized with the Holy Spirit” (Acts 1:5). This promise was fulfilled on the Day of Pentecost (Acts 2:1–4);
I'll come back and say more about this~I am convinced you are wrong in saying this. I know you are not alone in believing this, but, I know the scriptures will say differently than what you are saying~no pun intended, just desire for all of us to be as close to the truth as we can be.for the first time, people were permanently indwelt by the Holy Spirit, and the church had begun.
