Result of the Sermon. The Holy Spirit comes as a rule at baptism, but here, before anything is said about baptism, Peter's speech is interrupted by the descent of the Spirit. Those who had come with Peter from Joppa knew at once what had happened when they heard the Gentile hearers break out into speaking with tongues and praising God. They were surprised that this should happen to Gentiles; Jews alone till now had had these visitations. Peter's reply to their exclamations was that one part of baptism had already taken place with these people, so that God Himself had solved the question of their reception into the Church. Could anyone refuse them the other part of baptism, the water? They are at once baptized; the Church is opened by Peter's means to the Gentiles.

44 While Peter yet spake these words, the Holy Ghost fell on all them which heard the word.
45 And they of the circumcision which believed were astonished, as many as came with Peter, because that on the Gentiles also was poured out the gift of the Holy Ghost.
46 For they heard them speak with tongues, and magnify God. Then answered Peter,
47 Can any man forbid water, that these should not be baptized, which have received the Holy Ghost as well as we?
48 And he commanded them to be baptized in the name of the Lord. Then prayed they him to tarry certain days.
