44While Peter was still speaking these words, the Holy Spirit fell upon all those who were listening to the message. 45All the circumcised believers who came with Peter were amazed, because the gift of the Holy Spirit had been poured out on the Gentiles also. 46For they were hearing them speaking with tongues and exalting God. Then Peter answered, 47“Surely no one can refuse the water for these to be baptized who have received the Holy Spirit just as we did, can he?” 48And he ordered them to be baptized in the name of Jesus Christ. Then they asked him to stay on for a few days. Acts 10:44-48 NASB
Kinda makes you wonder sometimes if roman catholics read the NT in context....oh wait. Nevermind.
Those who have the Holy Spirit have already been saved.
That baptism wasn’t to save them, it was for those who had been saved.
