Instituted by Lord Jesus when He said: “If anyone thirsts let him come to Me and drink. He who believes in Me, as the Scripture has said, out of his heart will flow rivers of living water”. But this He spoke concerning the Spirit whom those believing in Him would receive; for the Holy Spirit was not yet given, because Jesus was not yet glorified” (John 7:37-39). About the Sacrament of Confirmation, in the Book of Acts it is mentioned : “Now when the Apostles who were at Jerusalem heard that Samaria had received the Word of God, they sent Peter and John to them, who, when they had come down, prayed for them that they might receive the Holy Spirit. For as yet He had fallen upon none of them. They had only been baptized in the name of the Lord Jesus. Then they laid hands on them, and they received the Holy Spirit” (Acts 8:14-17).
The Holy Spirit was received by the laying of hands, but when the number of believers increased, the Apostles were unable to keep track of each individual to lay upon them their hands in order to receive the Holy Spirit. So they made the Myron out of certain oils mixed with spices; the same spices which were brought to the tomb to embalm the shrouded Christ. It was approved for the dwelling of the Holy Spirit, and allowed the priests to anoint the newly baptized by the Myron to receive the gift of the Holy Spirit, to dwell in them, in order to become temples of the Holy Spirit.
