Extra Note from Father Andrew:
In chapter 8, it is noteworthy that the apostles are conferring the gift of the Holy Spirit through what we would later call the Sacrament of Confirmation, even though they did not yet have this name. They are able to do this because they have authority from Jesus; like Confirmation, this authority is also passed on in Acts through the laying on of hands, which we would later call the Sacrament of Holy Orders. Simon the Magician sins by asking to pray to be given the gift of Holy Orders. This is where the word “simony” comes from, meaning the sinful practice of selling positions of leadership in the Church.
