The great power of God - Probably this means only that they believed that he was "invested with" the power of God, not that they supposed he was really the Great God.

This man is the great power of God - That is, he is invested with it, and can command and use it. They certainly did not believe him to be God; but they thought him to be endued with a great supernatural power.

There is a remarkable reading here in several MSS. which should not pass unnoticed. In ABCDE, several others, together with the Ethiopic, Armenian, later Syriac, Vulgate, Itala, Origen, and Irenaeus, the word καλουμενη is added before μεγαλη, and the passage reads thus, This person is that power of God which is Called the Great. This appears to be the true reading; but what the Samaritans meant by that power of God which they termed the Great, we know not. Simon endeavored to persuade the people that he was a very great personage, and he succeeded.

To whom they all gave heed,.... Were not only attentive to the strange things he did, and to the wonderful things he gave out concerning himself; but they believed what he said and did as real things, and were obedient to him: and that

from the least to the greatest; which does not so much respect age, though the Ethiopic version renders it, "from the younger of them to the eldest of them", as state and condition; persons of every rank and quality, high and low, rich and poor, magistrates and subjects, from the meanest to the greatest of them; and so the Syriac version renders it, "both great", or "noble, and mean"; he drew the attention, and commanded the regard, both of princes and peasants, of the learned and unlearned, of the great men, and of the common people, who one and all wondered at him, and applauded him:

saying, this man is the great power of God; or as the Alexandrian copy and some others, and the Vulgate Latin version read, "this is the power of God which is called great"; they took him for the supreme Deity, or as Justin Martyr (h) expresses it, they accounted him the first, or chief God, or they looked upon him to be the Messiah, "the great power of God": as the Syriac version renders it; and who should be great, and called the Son of the Highest, Luke 1:32.

The great power of God

The best texts add ἡ καλουμένη, which is called, and render that power of God which is called great. They believed that Simon was an impersonated power of God, which, as the highest of powers, they designated as the great.

To whom they all gave heed, from the least to the greatest, saying, This man is the great power of God.

8:10 This man is the great power of God. Unable to explain the things that he did, the Samaritans ascribed them to divine power manifested through Simon.

10. To whom all gave heed . because of long time he had bewitched them-This, coupled with the rapidity with which they deserted him and attached themselves to Philip, shows the ripeness of Samaria for some religious change.

8:5-13 As far as the gospel prevails, evil spirits are dislodged, particularly unclean spirits. All inclinations to the lusts of the flesh which war against the soul are such. Distempers are here named, the most difficult to be cured by the course of nature, and most expressive of the disease of sin. Pride, ambition, and desire after grandeur have always caused abundance of mischief, both to the world and to the church. The people said of Simon, This man is the great power of God. See how ignorant and thoughtless people mistake. But how strong is the power of Divine grace, by which they were brought to Christ, who is Truth itself! The people not only gave heed to what Philip said, but were fully convinced that it was of God, and not of men, and gave up themselves to be directed thereby. Even bad men, and those whose hearts still go after covetousness, may come before God as his people come, and for a time continue with them. And many wonder at the proofs of Divine truths, who never experience their power. The gospel preached may have a common operation upon a soul, where it never produced inward holiness. All are not savingly converted who profess to believe the gospel.
