Acts 11:15

"And as. began to speak, the Holy Spirit fell on them, even as on us at the beginning"Even as on us at the beginning" "Just as" (Wey). The reference to the phrase, "the beginning", clearly points us to Pentecost, because this is the "beginning" of the Church (Acts 2:47). This chapter records the only other outpouring the Spirit recorded in the book of Acts. The "us" must be limited to the apostles, for on the day of Pentecost the Holy Spirit solely fell upon them, see Acts 1:4; Acts 1:8; Acts 2:1; Acts 2:14; Acts 2:43). "It is strongly implied that there had been no common reception of the baptism with the Holy Spirit since Pentecost, for if it were something that all Christians were expected to, and did receive, Peter could have simply pointed to the numerous other incidents and not have had to go back to Pentecost for an example. The inference also can be drawn that the 'baptism of the Holy Spirit' was not the thing that converted people, for Peter could have shown that the conversion of Cornelius was like the case of any other person who came to Christ to prove his point" (Reese p. 411). From this point it has been some 8-10 years since Pentecost.
