Interesting, so the baptism Peter is referring to is signifying the baptism of the Holy Spirit?
Does that mean one must receive the baptism of the Holy Spirit in order to be saved?
1 Peter 3:21 (KJV) The like figure whereunto even baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ:
All who are Christians have been baptized with the Holy Spirit.
It is this event that places a person into the body of Christ.
Drinking of one Spirit occurs when He is
received.
1 Corinthians 12:13
For
by one Spirit we were all baptized into one body, whether Jews or Greeks, whether slaves or free, and we were all made to
drink of one Spirit.
John 7:37-39
(37) Now on the last day, the great
day of the feast, Jesus stood and cried out, saying, “If anyone is thirsty, let him come to Me and
drink.
(38) He who believes in Me, as the Scripture said, ‘From his innermost being will flow rivers of living water.’”
(39) But this He spoke of
the Spirit, whom those who believed in Him were to
receive; for the Spirit was not yet
given, because Jesus was not yet glorified.
Acts 10:47-48
(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?”
(48) And he ordered them to be baptized in the name of Jesus Christ. Then they asked him to stay on for a few days.
Since the Holy Spirit was
received by the Gentiles (Acts 10:47) before their water baptism (Acts 10:48) proves they did "drink of one Spirit"
(1 Corinthians 12:13)
before their water baptism. Thus, the baptism mentioned in 1 Corinthians 12:13 refers to being baptized with the Holy Spirit.
This baptism places a person into the body of Christ.
