Now when the Day of Pentecost had fully come, they were all with one accord in one place. And suddenly there came a sound from heaven, as of a rushing mighty wind, and it filled the whole house where they were sitting. Then there appeared to them divided tongues, as of fire, and one sat upon each of them. And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit gave them utterance. Now there were dwelling in Jerusalem Jews, devout men, from every nation under heaven. And when this sound occurred, the multitudes came together, and were confused, because everyone heard them speak in his own language. Then they were all amazed and marveled, saying to one another, “Look, are not all these who speak Galileans?”And how is it that we hear, each in our own language in which we were born? “Parthians and Medes and Elamites, those dwelling in Mesopotamia, Judea and Cappadocia, Pontus and Asia, “Phrygia and Pamphylia, Egypt and the parts of Libya adjoining Cyrene, visitors from Rome, both Jews and proselytes, “Cretans and Arabs; we hear them speaking in our own tongues the wonderful works of God.” (Acts 2:1-11)
“We believe that in the Church the Old Testament prophecy has been fulfilled: ‘And in the last days it shall be, God declare, that I will pour out my Spirit upon all flesh’ (Acts 2:17). God pours out his Spirity not upon just a certain member but upon all His people. All are charismatics since all have received the Spirit as a ‘pledge’ (arrabôn) of the new age to which the Church belongs while still abiding in this old age. The Church is the beginning of the ‘last days’ (eschatai hemerai).
Upon entering, the believer is set apart for ministry in the Church through the sending down of the Spirit. ‘The fullness of grace’ (omnis gratia) has an absolute but not relative, a permanent but not temporary, character, for only charismatics can be members of the Church. The gift of the Spirit that every member of the faithfull receives in the sacrament of initiation is the charism of royal priesthood. In the Church there are no gifts of the Spirit without ministry and there is no ministry without gifts. Through the charisma of the royal priesthood the Christian is call to priestly ministry in the Church.” (Nicholas Afanasiev, The Church of the Holy Spirit, pg. 3)
