Acts 8:18

Simon … offered them money. From hence it is called the sin of simony, to buy, sell, or give money for benefices, and spiritual things. It was vanity that made Simon desire this power. (Witham) — Hence to give or receive money in exchange, or as a price for any spiritual good whatever, is justly esteemed sinful. It is called simony, from the name of the person, who was first engaged in this sin. (Haydock) — Simon acts the part of a tempter to the apostles, and wishes to draw them into prevarication, by offering money for what was above all price, and of what they were not the proprietors, but the dispensers. (St. Clement of Rome)

1. The wicked proposal that Simon made, by which his hypocrisy was discovered (v. 18, 19): When he saw that through laying on of the apostles' hands the Holy Ghost was given (which should have confirmed his faith in the doctrine of Christ, and increased his veneration for the apostles), it gave him a notion of Christianity as no other than an exalted piece of sorcery, in which he thought himself capable of being equal to the apostles, and therefore offered them money, saying, Give me also this power. He does not desire them to lay their hands on him, that he might receive the Holy Ghost himself (for he did not foresee that any thing was to be got by that), but that they would convey to him a power to bestow the gift upon others. He was ambitious to have the honour of an apostle, but not at all solicitous to have the spirit and disposition of a Christian. He was more desirous to gain honour to himself than to do good to others. Now, in making this motion, (1.) He put a great affront upon the apostles, as if they were mercenary men, would do any thing for money, and loved it as well as he did; whereas they had left what they had, for Christ, so far were they from aiming to make it more—(2.) He put a great affront upon Christianity, as if the miracles that were wrought for the proof of it were done by magic arts, only of a different nature from what he himself had practised formerly. (3.) He showed that, like Balaam, he aimed at the rewards of divination; for he would not have offered money for this power if he had not hoped to get money by it. (4.) He showed that he had a very high conceit of himself, and that he had never his heart truly humbled. Such a wretch as he had been before his baptism should have asked, like the prodigal, to be made as one of the hired servants. But, as soon as he is admitted into the family, no less a place will serve him than to be one of the stewards of the household, and to be entrusted with a power which Philip himself had not, but the apostles only.

Verses 14-25 The Holy Ghost was as yet fallen upon none of these coverts, in the extraordinary powers conveyed by the descent of the Spirit upon the day of Pentecost. We may take encouragement from this example, in praying to God to give the renewing graces of the Holy Ghost to all for whose spiritual welfare we are concerned; for that includes all blessings. No man can give the Holy Spirit by the laying on of his hands; but we should use our best endeavours to instruct those for whom we pray. Simon Magus was ambitious to have the honour of an apostle, but cared not at all to have the spirit and disposition of a Christian. He was more desirous to gain honour to himself, than to do good to others. Peter shows him his crime. He esteemed the wealth of this world, as if it would answer for things relating to the other life, and would purchase the pardon of sin, the gift of the Holy Ghost, and eternal life. This was such a condemning error as could by no means consist with a state of grace. Our hearts are what they are in the sight of God, who cannot be deceived. And if they are not right in his sight, our religion is vain, and will stand us in no stead. A proud and covetous heart cannot be right with God. It is possible for a man to continue under the power of sin, yet to put on a form of godliness. When tempted with money to do evil, see what a perishing thing money is, and scorn it. Think not that Christianity is a trade to live by in this world. There is much wickedness in the thought of the heart, its false notions, and corrupt affections, and wicked projects, which must be repented of, or we are undone. But it shall be forgiven, upon our repentance. The doubt here is of the sincerity of Simon's repentance, not of his pardon, if his repentance was sincere. Grant us,…
