The Sacrament of Confirmation

Now when the apostles at Jerusalem heard that Samar′ia had received the word of God, they sent to them 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. Then they laid their hands on them and they received the Holy Spirit.
Acts 8:14-17
