(38) And John answered him.--The incident that follows, omitted by St. Matthew, is recorded by St. Luke in the same connection. It indicates something of the same zeal as that which desired that fire might come from heaven to consume the Samaritans who refused to receive our Lord (Luke 9:52). The words were so far an "answer" to what our Lord had said, that they were suggested by it. The disciple desired to show, as in self-vindication, that he not only "received" his Master, but that he was unwilling to "receive" any who did not openly follow Him as a disciple. The fact of which he speaks is significant historically as indicating that one of the effects of our Lord's work had been to stir up and quicken the spiritual powers of men outside the range of the company of disciples that gathered round Him. They believed in Him, or they would not have used His Name. They were fellow-workers with Him, for they were seeking to rescue the souls of men from frenzy and despair. Their faith was effective, for, as the narrative implies, they not only claimed the power to cast out demons, but did cast them out. The case stood, it is obvious, on an entirely different footing from that of the sons of Sceva, in Acts 19:13-14, which at first sight seems to resemble it.

Verse 38. - This verse, according to the best authorities, should begin simply, John said unto him - although in St. Luke (Luke 9:49) they stand, "And John answered and said" - Master, we saw one casting out devils in thy name: and we forbade him, because he followed not us. The casting out of evil spirits was one of the foremost signs of apostleship; and what surprised St. John was that one who followed not Christ should have been able to work this miracle - a miracle in which, it will be remembered, the disciples had recently failed. It thus appears that our Lord's teaching had been so influential, that some, not reckoned amongst his disciples, had shown this proof of a strong and overpowering faith. We know that there were those in our Savior's time, of Jewish race, who cast out devils (Matthew 12:27). And Justin Martyr, in his 'Dialogue with Trypho the Jew,' states that while exorcism, as practiced by the Jews, often failed when it was attempted to be exercised "by the God of Abraham, Isaac, and Jacob," was eminently successful when administered "by the name of the Son of God, who was born of a virgin and crucified under Pontius Pilate" (c. 85). That spirit has power over spirit in many mysterious ways is one of those truths which science has not yet been able to explain (see Dr. Morison on St. Mark, in loc.). To return, however, to the instance here alluded to by St. John, it should be observed that they who acted thus had faith in Christ; and that by thus acting with him and for him, though not amongst his recognized followers, they contributed towards his honor who, by means of these imperfect instruments, carried out the great purpose of his manifestation, namely," to destroy the works of the devil." Then further, the disciples forbade them not out of envy or hatred, but out of zeal for Christ, as though they were thus serving his cause and upholding his honor. But this was" a zeal, not according to knowledge." They had forbidden them, without having first taken counsel of their Master.

9:30-40 The time of Christ's suffering drew nigh. Had he been delivered into the hands of devils, and they had done this, it had not been so strange; but that men should thus shamefully treat the Son of man, who came to redeem and save them, is wonderful. Still observe that when Christ spake of his death, he always spake of his resurrection, which took the reproach of it from himself, and should have taken the grief of it from his disciples. Many remain ignorant because they are ashamed to inquire. Alas! that while the Saviour teaches so plainly the things which belong to his love and grace, men are so blinded that they understand not his sayings. We shall be called to account about our discourses, and to account for our disputes, especially about being greater than others. Those who are most humble and self-denying, most resemble Christ, and shall be most tenderly owned by him. This Jesus taught them by a sign; whoever shall receive one like this child, receives me. Many have been like the disciples, ready to silence men who have success in preaching to sinners repentance in Christ's name, because they follow not with them. Our Lord blamed the apostles, reminding them that he who wrought miracles in his name would not be likely to hurt his cause. If sinners are brought to repent, to believe in the Saviour, and to live sober, righteous, and godly lives, we then see that the Lord works by the preacher.And John answered him, saying,.... Taking notice of what Christ just now said, and observing how well pleasing it was to him, to receive in a meek and humble manner, the least believer in his name; and reflecting upon an action, in which he and some of his fellow disciples were concerned, and which he perceived was not so agreeable to this rule of Christ, thought proper to relate it to him; that he might have his sense of it, and give him an opportunity of enlarging on a subject, so suitable to the temper and disposition of this beloved disciple.

Master, we saw one casting out devils in thy name: very likely he called him Rabbi, as the Syriac version renders it, or Rabboni, as in John 20:16, a title commonly given to Christ, both by his disciples and others: the case related, very probably happened, when the disciples being sent forth by Christ to preach the Gospel and cast out devils, took a tour through Judea and Galilee, where they saw this man. John was not alone; there were others with him, at least another, who was an eyewitness with him; for the apostles were sent out, by two and two: who this man was, is not said, his name is not mentioned, perhaps was unknown to the apostles; though Beza says, in one ancient exemplar it is read, "we knew one". This person not only attempted to cast out devils, but really did; and that more than one; but in which of Christ's names he did it, is not expressed; if in the name of the Messiah, Dr. Lightfoot's conjecture may be right, that he was one of John's disciples; who had been baptized in the name of the Messiah, that was just expected to come; to whom, as to others of his disciples, was given a power of casting out devils, to make the way of the Messiah more plain; wherefore the reason why he did not cast out devils in the name of Jesus, but in the name of the Messiah, and did not follow him, nor his disciples, was not out of contempt, but ignorance, not knowing that Jesus of Nazareth was the Messiah: or if he cast out devils in the name of Jesus, which seems most likely, he might be, as others think, a disciple of John's, who really did believe in Jesus, though he did not associate with, his disciples, but continued with the disciples of John: wherefore it is said,

and he followeth not us; was neither one of the twelve apostles; nor one of the seventy disciples; nor even one of the lower class of the professed disciples of Jesus. This clause is omitted in the Syriac, Arabic, Persic, and Ethiopic versions:

and we forbad him; going on in this way, casting out any more devils:

because he followeth, not us; was not one of their company, nor any of Christ's disciples; who had received no authority and commission from Christ, to do what he did: wherefore they feared, that by such an irregular way of proceeding, the dignity of Christ would be lessened, and some dishonour and reproach reflected on him: and besides the honour of Christ, they might consult their own; and their case be too much like that of Joshua, when Eldad and Medad prophesied in the camp. This clause is left out in the Vulgate Latin, but stands in all the eastern versions.
