ministry, by explicitly connecting the earlier prophecy of John the Baptist to the baptism of the disciples with the Holy Spirit on the day of Pentecost. The timing of the narrative during the law giving festival of Pentecost symbolizes both continuity with the giving of the law, but also the central role of the Holy Spirit for the early church. The central role of Christ in Christian faith signified a fundamental theological separation from the traditional Jewish faith, which was grounded in the Torah and Mosaic Law. Peter's sermon in stresses the resurrection and exaltation. In his sermon, Peter quotes Joel 2:28–32 and Psalm 16 to indicate that first Pentecost marks the start of the Messianic Age. About one hundred and twenty followers of Christ (Acts 1:15) were present, including the Twelve Apostles (Matthias was Judas' replacement) (Acts 1:13, 26), Jesus' mother Mary, other female disciples and his brothers (). While those on whom the Spirit had descended were speaking in many languages, the Apostle Peter stood up with the eleven and proclaimed to the crowd that this event was the fulfillment of the prophecy. In Acts 2:17, it reads: "'And in the last days,' God says, 'I will pour out my spirit upon every sort of flesh, and your sons and your daughters will prophesy and your young men will see visions and your old men will dream dreams." He also mentions (Acts 2:15) that it was the third hour of the day (about 9:00 am). Acts 2:41 then reports: "Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls." Critical scholars believe some features of the narrative are theological constructions. Scholars believe that even if the Pentecost narrative is not literally true, it does signify an important event in the history of the early church which enabled the rapid spread of Christianity. Within a few decades important congregations had been established in all major cities of the Roman Empire. Biblical commentator Richard C. H. Lenski has noted that the use of the term "Pentecost" in Acts is a reference to the Jewish festival. He writes that a well-defined, distinct Christian celebration did not exist until later years, when Christians kept the name of "Pentecost" but began to calculate the date of the feast based on Easter rather than Passover. Peter stated that this event was the
