‘Now when Simon saw that through the laying on of the apostles' hands the Holy Spirit was given, he offered them money, saying, “Give me also this power, that on whoever I lay my hands, he may receive the Holy Spirit.” '
Simon had possibly gained great wealth by training up disciples and enabling them to practise what he practised, and he had probably himself also bought information on how to perform sorcery from other practitioners. (Many wonder workers travelled around the Roman world practising their arts, amazing people by their tricks, and in some cases genuinely believing that they had some supernatural power, and it was no doubt standard practise to charge for expertise). Thus when he saw that the Apostles were able to give the Holy Spirit simply by the laying on of hands, a gift which manifested itself in the exalting of men's hearts to God, he naturally assumed that their ability could be bought and paid for. Here were wonder workers on a large scale. He therefore probably offered them a great deal of money. To his mind this was something worth having. He would not think that he was acting against God. Did he not want the gift so that he could serve God? But where he failed was in not recognising that God came under no man's control. He had to be delivered from his mind set. He had to learn that what God gave was free for all who would rightly believe, and not within man's control.
In the idolatrous world priesthoods could be bought and sold, along with the supposed influences that they exerted on the gods. And it is salutary to think that had he approached a much later church they would gladly have given him what they thought was this gift in return for money and submission to them. Like Simon the later church would try to control God's activity and make it subject to their will. But in what happened to Simon here all future ‘sacerdotal priesthood' is condemned. That had failed miserably in the Old Testament era. Now God gave freely and with no strings attached, in cooperation with those who were truly devoted to Him, because of the sacrifice offered once for all in Jesus Christ.
