This is what it was before the Pentecostal movement came along and gave it a new meaning. I has caused much damage, confusing many on what the baptism of the Holy Spirit really is.
And yet Pentecostals are more scripturally based on this. Of all five instances of people being baptized in the Holy Spirit in Acts, none of them happened at the instance of salvation.
All the great theologians, the ones whose work I've read
You've obviously never read Smith-Wigglesworth, Derek Prince, David Wilkerson or John Hagee.
Acts 8:14; Now when the apostles in Jerusalem heard that Samaria had received the word of God, they sent them Peter and John,
Acts 8:15; who came down and prayed for them
that they might receive the Holy Spirit.
Acts 8:16; For He had not yet fallen upon any of them; they had simply been baptized in the name of the Lord Jesus.
Acts 19:2 He said to them, "
Did you receive the Holy Spirit when you believed?" And they said to him,
"No, we have not even heard whether there is a Holy Spirit."
Acts 19:3 And he said, "Into what then were you baptized?" And they said, "Into John's baptism."
Acts 10:1; Now there was a man at Caesarea named Cornelius, a centurion of what was called the Italian cohort,
Acts 10:2;
a devout man and one who feared God with all his household, and gave many alms to the Jewish people and prayed to God continually.
Acts 10:44; While Peter was still speaking these words,
the Holy Spirit fell upon all those who were listening to the message.
Acts 10:45; All the circumcised believers who came with Peter were amazed, because
the gift of the Holy Spirit had been poured out on the Gentiles also.
It would seem that those who believe in the baptism of the Holy Spirit at the instant of salvation are the ones who are confused.
Acts 9:8; Saul got up from the ground, and though his eyes were open, he could see nothing; and leading him by the hand, they brought him into Damascus.
Acts 9:9; And he was
three days without sight, and neither ate nor drank.
Acts 9:17; So Ananias departed and entered the house, and after laying his hands on him said, "Brother Saul, the Lord Jesus, who appeared to you on the road by which you were coming, has sent me
so that you may regain your sight and be filled with the Holy Spirit."
Luke 11:13; "If you then, being evil, know how to give good gifts to your children, how much more will your heavenly Father give the Holy Spirit
to those who ask Him?"
