Luke said that they all preached the Word of God, now he maketh mention of Philip alone, both because his preaching was more fruitful and effectual than the preaching of the rest, and also because there followed notable histories, which he will add afterward. He put the city of Samaria for the city Samaria which was laid waste by Hyrcanus, and built again by Herod, and called Sebaste. Read Josephus, in his Thirteenth and Fifteenth Books of Antiquities. When he saith that Philip preached Christ, he signifieth that the whole sum of the gospel is contained in Christ. The other speech which he useth shortly after is more perfect; yet it all one in effect. He joineth the kingdom of God and the name of Christ together; but because we obtain this goodness through Christ, to have God to reign in us, and to lead an heavenly life, being renewed into spiritual righteousness, and dead to the world, therefore the preaching of Christ containeth this point also under it. But the sum is this, that Christ doth repair with his grace the world, being destroyed; which cometh to pass when he reconcileth us to the Father. Secondly, when he regenerateth us by his Spirit, that the kingdom of God may be erected in us when Satan is put to flight. Moreover, whereas he declared before, that the apostles did not stir one foot from Jerusalem, it is to be thought that he speaketh of one of the seven deacons in this place, whose daughters did also prophesy.

Then Philip - One of the seven deacons, Acts 6:5. He is afterward called the "evangelist," Acts 21:8.
The city of Samaria - This does not mean a city whose "name" was Samaria, for no such city at that time existed. Samaria was a "region," Matthew 2:22. The ancient city Samaria, the capital of that region, had been destroyed by Hyrcanus, so completely as to leave no vestige of it remaining; and he "took away," says Josephus, "the very marks that there had ever been such a city there" (Antiq., book 13, chapter 10, section 3). Herod the Great afterward built a city on this site, and called it "Sebaste"; that is, "Augusta," in honor of the Emperor Augustus (Josephus, Antiq., book 15, chapter 8, section 5). Perhaps this city is intended, as being the principal city of Samaria; or possibly "Sychar," another city where the gospel had been before preached by the Saviour himself, John 4.
And preached Christ - Preached that the Messiah had come, and made known his doctrines. The same truths had been before stated in Samaria by the Saviour himself John 4; and this was doubtless one of the reasons why they so gladly now received the Word of God. The field had been prepared by the Lord Jesus. He had said that it was white for the harvest John 4:35, and into that field Philip now entered, and was signally blessed. His coming was attended with a remarkable "revival of religion." The word translated "preach" here is not what is used in the previous verse. This denotes to "proclaim as a crier," and is commonly employed to denote the preaching of the gospel, so called, Mark 5:20; Mark 7:36; Luke 8:39; Matthew 24:14; Acts 10:42; Romans 10:15; 1-Corinthians 9:27; 1-Corinthians 15:12; 2-Timothy 4:2. It has been argued that because "Philip" is said thus to have preached to the Samaritans, that "therefore" all "deacons" have a right to preach, or that they are, under the New Testament economy, an "order" of ministers. But this is by no means clear. For:
(1) It is not evident, nor can it be shown, that the "other" deacons Acts 6:1-15 ever preached. There is no record of their doing so; and the narrative would lead us to suppose that they did not.
(2) they were "appointed" for a very different purpose Acts 6:1-5; and it is fair to suppose that, as "deacons," they confined themselves to the design of their appointment.
(3) it is not said that "Philip" preached in virtue of his being a "deacon." From anything in "this" place, it would seem that he preached as the other Christians did - wherever he was.
(4) but "elsewhere" an express distinction is made between Philip and the others. A new appellation is given him, and he is expressly called the "evangelist," Acts 21:8. From this, it seems that he preached, not "because" he was a "deacon," but because he had received a special "appointment" to this business as an evangelist.
(5) this same office, or rank of Christian teachers, is expressly recognized elsewhere, Ephesians 4:11. All these considerations show that there is "not" in the sacred Scriptures an order of ministers appointed to preach "as deacons."

Then Philip - One of the seven deacons, Acts 6:5, called afterwards, Philip the Evangelist, Acts 21:8.
The city of Samaria - At this time there was no city of Samaria existing: according to Josephus, Ant. lib. xiii. cap. 10, sect. 3, Hyrcanus had so utterly demolished it as to leave no vestige of it remaining. Herod the Great did afterwards build a city on the same spot of ground; but he called it ΣεβαϚη i.e. Augusta, in compliment to the Emperor Augustus, as Josephus tells us, Ant. lib. xv. cap. 8, sect. 5; War, lib. i. cap. 2. sect. 7; and by this name of Sebast, or Augusta, that city, if meant here, would in all probability have been called, in the same manner as the town called Strato's Tower, (which Herod built on the sea coasts, and to which he gave the name of Caesarea, in compliment to Augustus Caesar), is always called Caesarea, wherever it is mentioned in the Acts of the Apostles. Bp. Pearce.
As Sychem was the very heart and seat of the Samaritan religion, and Mount Gerizim the cathedral church of that sect, it is more likely that it should be intended than any other. See Lightfoot. As the Samaritans received the same law with the Jews, as they also expected the Messiah, as Christ had preached to and converted many of that people, John 4:39-42, it was very reasonable that the earliest offers of salvation should be made to them, before any attempt was made to evangelize the Gentiles. The Samaritans, indeed, formed the connecting link between the Jews and the Gentiles; for they were a mongrel people, made up of both sorts, and holding both Jewish and Pagan rites. See the account of them on Matthew 10:5 (note).

(4) Then Philip went down to the city of Samaria, and preached Christ unto them.
(4) Philip, who was before a deacon in Jerusalem, is made an evangelist by God in an extraordinary way.

Then Philip went down to the city of Samaria,.... The city which was formerly called Samaria, but now Sebaste; it had been destroyed by Hyrcanus, and was rebuilt by Herod; and called by him, in honour of Augustus, by the name of Sebaste (d); and so R. Benjamin says (e), that
"from Luz he came in a day to Sebaste, , "this is Samaria"; where yet may be discerned the palace of Ahab king of Israel-----and from thence are two "parsas" to Neapolis, this is Sichem.''
Which last place, Sichem, is by Josephus said to be the "metropolis" of Samaria; and is thought by Dr. Lightfoot to be the city Philip went to, and where our Lord had before been, and preached to the conversion of many persons: this place lay lower than Jerusalem, and therefore Philip is said to go down to it; and who was not Philip the apostle, but Philip the deacon, for the apostles abode at Jerusalem; and beside, though this Philip preached the Gospel, and baptized, and wrought miracles, yet did not lay on hands, in order that persons might receive the extraordinary gifts of the Holy Ghost; this was peculiar to the apostles, and therefore Peter and John came down for this purpose, when they heard of the success of Philip's ministry: the subject matter of which follows:
and preached Christ unto them; that Christ was come in the flesh, that Jesus of Nazareth was the Christ, and that he was the Son of God, and the alone Saviour of men; who by his obedience, sufferings, and death, had wrought righteousness, procured peace and pardon, and obtained eternal redemption for his people; and was risen again, and ascended into heaven, and was set down at the right hand of God, where he ever lived to make intercession, and would come again a second time to judge both quick and dead.

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.

SUCCESS OF PHILIP'S PREACHING IN SAMARIA--CASE OF SIMON MAGUS. (Acts 8:5-25)
Then Philip--not the apostle of that name, as was by some of the Fathers supposed; for besides that the apostles remained at Jerusalem, they would in that case have had no occasion to send a deputation of their own number to lay their hands on the baptized disciples [GROTIUS]. It was the deacon of that name, who comes next after Stephen in the catalogue of the seven, probably as being the next most prominent. The persecution may have been directed especially against Stephen's colleagues [MEYER].
the city of Samaria--or "a city of Samaria"; but the former seems more likely. "It furnished the bridge between Jerusalem and the world" [BAUMGARTEN].

Philip went down to the city of Samaria. This was not Philip, the apostle, for all the apostles remained at Jerusalem, but Philip, one of the seven (Acts 6:5).
The city of Samaria. The Greek does not render it certain that this was the capital named Samaria, as there is no definite article. It is literally "a city of Samaria." The district (see map) lies between Judea and Galilee. Samaria and Sychar were, at this time, two of its principal cities. It was probably one or the other of these to which Philip went.

Stephen - Being taken away, Philip, his next colleague, (not the apostle,) rises in his place.
