What is meant by "receive the Holy Spirit" (Acts 8:15 &
19)?
The conversion of the human heart, which only the Holy Spirit can
accomplish, isn't immediately and visually observable. Given that Simon
"saw" (Acts 8:18) the manifestation of the Holy
Spirit when Peter and John "lay hands" (Acts
8:19) on the people, the context of this passage makes it likely that the new
Christians of Samaria were receiving the observable gifts of the Holy Spirit
when Peter and John touched and prayed for them.
What could those gifts have been?
επιπεπτωκος (epipeptokos), the original Greek
word translated "fallen" in Acts 8:16
is derived from the
same root verb as επεπεσεν (epepesen), the
original Greek word that is translated "fell" in Acts
10:44 (see
Holy Spirit falls): 44
While Peter was still speaking these words, the Holy Spirit fell upon all
those who heard the word. 45
And those of the circumcision who believed were astonished, as many as came
with Peter, because the gift of the Holy Spirit had been poured out on the
gentiles also. 46
For they heard them speak with tongues and magnify God. Then Peter answered,
47 “Can anyone
forbid water, that these should not be baptized who have received the Holy
Spirit just as we have?” (Acts 10:44-47). Notice that Peter simply
declared that the recipients had "received the Holy
Spirit" (Acts 10:47) to refer to the fact that they had received the
"gift" (Acts 10:45) of
"tongues" (Acts 10:46). Therefore, the gift of tongues could
have been one of the manifestations of the Holy Spirit that
"Simon saw" (Act 8:18) as well.
But wasn't the Holy Spirit visible as a dove when He descended on Jesus upon His baptism?
Yes, but it was for the unique purpose of identifying Jesus as the Son of
God (see
Lamb of God).
Why might the Lord have delayed the gift of the Holy Spirit
to the Samaritans until Peter and John came to them?
To have Peter and John return to Jerusalem and share with any skeptics among
the Jewish Christians the 'proof' that
God had expanded the church to include even the Samaritans. Also,
the new Samaritan Christians could have claimed independence from the church in Jerusalem if they had received the gift of the Holy
Spirit from someone else laying hands on them. The Lord was keeping the growing
church united in Christ.
