They had not yet received the Holy Spirit

In Acts 8, we read of Philip the deacon (whom Chrysostom says is not the Philip of Acts 9) preaching in Samaria. When the apostles heard that the Word of God was received in Samaria, they sent Peter and John, “who came down and prayed for them that they might receive the Holy Spirit; for it had not yet fallen on any of them, but they had only been baptized in the name of the Lord Jesus” (8:15-16).

St. Paul writes that no one calls Jesus “Lord” except by the Spirit, and that no one says, “Jesus be accursed” except that they do not have the Spirit. Surely those who received Baptism in Samaria were calling Jesus Lord. Surely they hear the Word of the Lord from Philip the deacon, believed and were baptized. What is going on here, then, they the Spirit had not yet fallen on any of them?

I submit that this falling of the Spirit is not faith but the same falling as on the Day of Pentecost. Peter and John came and laid their hands on the Samaritans so that Spirit would continue the ministry among them.
