The chief difficulty connected with our passage is to make sure of the class of persons who are there in view. Is the Holy Spirit here describing regenerated or unregenerated souls? The next thing is to ascertain what is meant by, "If they shall fall away."The last, what is denoted by "It is impossible to renew them again unto repentance." Anticipating our exposition, we are fully assured that the "falling away" which is here spoken of signifies a deliberate, complete and final repudiation of Christa sin for which there is no forgiveness. So too we understand the "impossible" to renew them again to repentance, announces that their condition and case is beyond hope of recovery. Because of this, Calvinists have, generally, affirmed that this passage is treating of mere professors. But over against this there are two insuperable objections: first, mere professors have nothing from which to "fall away"; second, mere professors have never been "renewed" unto repentance.
The Greek word for "enlightened" here signifies "to give light or knowledge by teaching". It is so rendered by the Septuagint in Judges 13:8, 2 Kings 12:2, 17:27. The apostle Paul uses it for "to make manifest", or "bring to light" in 1 Corinthians 4:5, 2 Timothy 1:10. Satan blinds the minds of those who believe not, lest "the light of the gospel should shine unto them" (2 Cor. 4:4), that is, give the knowledge of it. Thus, "enlightened" here means to be instructed in the doctrine of the gospel, so as to have a clear apprehension of it. In the parallel passage in Hebrews 10:26 the same people are said to have "received the knowledge of the truth", cf. also 2 Peter 2:20, 21. It is, however, only a natural knowledge of spiritual things, such as is acquired by outward hearing or reading; just as one may be enlightened by taking up the special study of one of the sciences. It falls far short of that spiritual enlightenment which transforms (2 Cor. 3:18). An illustration of a unregenerate person being "enlightened", as here, is found in the case of Balaam; Numbers 24:4.
Second, they had "tasted" of the heavenly gift. To "taste" is to have a personal experience of, in contrast from mere report. "Tasting does not include eating, much less digesting and turning into nourishment what is so tasted; for its nature being only thereby discerned it may be refused, yea, though we like its relish and savor, on some other consideration. The persons here described, then, are those who have to a certain degree understood and relished the revelation of mercy; like the stony-ground hearers they have received the Word with a transcient joy" (John Owen). The "tasting" is in contrast from the "eating" of John 6:50-56.
Opinion is divided as to whether the "heavenly gift" refers to the Lord Jesus or the person of the Holy Spirit. Perhaps it is not possible for us to be dogmatic on the point. Really, the difference is without a distinction, for the Spirit is here to glorify Christ, as He came from the Father by Christ as His ascension "Gift" to His people. If the reference be to the Lord Jesus, John 3:16, 4:10, etc., would be pertinent references: if to the Holy Spirit, Acts 2:38, 8:20, 10:45, 11:17. Personally, we rather incline to the latter. This Divine Gift is here said to be "heavenly" because from Heaven, and leading to Heaven, in contrast from Judaismcf. Acts 2:2,1 Peter 1:12. Of this "Gift" these apostates had "tasted", or had an experience of: compare Matthew 27:34 where "tasting" is opposed to actual drinking. Those here in view had had an acquaintance with the Gospel, as to gain such a measure of its blessedness as to greatly aggravate their sin and doom. An illustration of this is found in Matthew 13:20, 21.
Third, they were "made partakers of the Holy Spirit". First, it should be pointed out that the Greek word for "partakers" here is a different one from that used in Colossians 1:12 and 2 Peter 1:4, where real Christians are in view. The word here simply means "companions", referring to what is external rather than internal. It is to be observed that this item is placed in the center of the five, and this because it describes the animating principle of the other four, which are all effects. These apostates had never been "born of the Spirit" (John 3:6), still less were their bodies His "temples" (1 Cor. 6:19). Nor do we believe this verse teaches that the Holy Spirit had, at any time, wrought within them, otherwise Philippians 1:6 would be contravened. It means that they had shared in the benefit of His supernatural operations and manifestations: "The place was shaken" (Acts 4:31) illustrates.
We quote below from Dr. J. Brown:
"It is highly probable that the inspired writer refers primarily to the miraculous gifts and operations of the Holy Spirit by which the primitive dispensation of Christianity was administered. These gifts were by no means confined to those who were transformed by the renewing of their minds. The words of our Lord in Matthew 7:22, 23 and of Paul in 1 Corinthians 13:1, 2 seem to intimate, that the possession of these unrenewed men was not very uncommon in that age; at any rate they plainly show that their possession and an unregenerate state were by no means incompatible".
"If they shall fall away". "This is scarcely a fair translation. It has been said that the apostle did not here assert that such persons did or do fall away; but that if they dida supposition which, however, could never be realizedthen the consequence would be they could not be renewed again unto repentance. The words literally rendered are, And have fallen away, or, yet have fallen. The apostle obviously intimates that such persons might, and that such persons did, fall away. By falling away, we are plainly to understand what is commonly called apostasy. This does not consist in an occasional falling into actual sin, however gross and aggravated; nor in the renunciation of some of the principles of Christianity, even though those should be of considerable importance; but in an open, total, determined renunciation of all the constituent principles of Christianity, and a return to a false religion, such as that of unbelieving Jews or heathens, or to open infidelity and open godlessness" (Dr. J. Brown).
"It is impossible . . . if they fall away, to renew them again unto repentance". Four questions here call for answer. What is meant by "renewed unto repentance"? What is signified by "renewed again unto repentance"? Why is such an experience "impossible"? To whom is this "impossible"? Repentance signifies a change of mind: Matthew 21:29, Romans 11:29 establish this. It is more than a mental act, the conscience also being active, leading to contrition and self-condemnation (Job 42:6). In the unregenerate, it is simply the workings of nature; in the children of God it is wrought by the Holy Spirit. The latter is evangelical, being one of the things which "accompany salvation". The former is not so, being the "sorrow of the world", which "worketh death" (2 Cor. 7:10). This kind of "repentance" or remorse receives most solemn exemplification in the case of Judas: Matthew 27:3, 5.Such was the repentance of these apostates. The Greek verb for "renew" here occurs nowhere else in the New Testament. Probably "restore" had been better, for the same word is used in the Sept., for a Hebrews verb meaning to renew in the sense of restore: Psalm 103:5; 104:30; Lamentations 5:21. Josephus applies it to the renovation of the Temple!
But what is meant by "renewing unto repentance"? "To be renewed is a figurative expression for denoting a change, a great change, and a change for the better. To be renewed so as to change a persons mind is expressive of an important and advantageous alteration of opinion, and character and service. And such an alteration the persons referred to had undergone at a former period. They were once in a state of ignorance respecting the doctrines and evidences of Christianity, and they had been enlightened. They had once known not of the excellency and beauty of Christian truth, and they had been made to taste of the heavenly gift. They once misunderstood the prophecies respecting the Messiah, and were unaware of their fulfillment, and, of course, were strangers to that energetic influence which the New Testament revelation puts forth; and they had been made to see that that good word was fulfilled, and had been made partakers of the external privileges and been subjected to the peculiar energies of the new order of things. Their view, and feelings, and circumstances, were materially changed. How great the difference between an ignorant, bigoted Jew, and the person described in the preceding passage! He had become as it were a different man. He had not, indeed, become, in the sense of the apostle, a new creature, His mind had not been so changed as unfeignedly to believe the truth as it is in Jesus; but still, a great and so far as it went, a thorough change had taken place" (Dr. J. Brown).
"Seeing they crucify to themselves the Son of God afresh" (verse 6). This is brought in to show the aggravation of their awful crime and the impossibility of their being renewed again unto repentance. By renouncing their Christian profession they declared Christ to be an Imposter. Thus they were irreclaimable. To attempt any further reasoning with them, would only be casting pearls before swine. With this verse should be carefully compared the parallel passage in Hebrews 10:26-29. These apostates had "received the knowledge of the truth", though not a saving knowledge of it. Afterward they sinned "wilfully": there was a deliberate and open disavowal of the truth. The nature of their particular sin is termed a "treading under foot the Son of God (something which no real Christian ever does) and counting (esteeming) the blood of the covenant an unholy thing", that is, looking upon the One who hung on the Cross as a common malefactor. For such there "remaineth no more sacrifice for sins". Their case is hopeless so far as man is concerned; and the writer believes, such are abandoned by God also.
"Seeing they crucify to themselves the Son of God afresh, and put Him to an open shame". "They thus identify themselves with His crucifiersthey entertained and avowed sentiments which were He on earth and in their power, would induce them to crucify Him. They exposed Him to infamy, made a public example of Him. They did more to dishonor Jesus Christ than His murderers did. Theynever professed to acknowledge His divine mission; but these apostates had made such a professionthey had made a kind of trial of Christianity, and, after trial, had rejected it" (Dr. J. Brown).
Such a warning was needed and well calculated to stir up the slothful Hebrews. Under the Old Testament economy, by means of types and prophecies, they had obtained glimmerings of truth as to Christ, called "the word of the beginning of Christ". Under those shadows and glimmerings they had been reared, not knowing their full import till they had been blessed with the full light of the Gospel, here called "perfection". The danger to which they were exposed was that of receding from the ground where Christianity placed them, and relaxing to Judaism. To do so meant to re-enter that House which Christ had left "desolate" (Matthew 23:38), and would be to join forces with His murderers, and thus "crucify to themselves the Son of God afresh", and by their apostasy "put Him to an open (public) shame". We may add that the Greek word here for "crucify" is a stronger one than is generally used: it means to "crucify up". Attention is thus directed to the erection of the cross on which the Savior was held up to public scorn.
Taking the passage as a whole, it needs to be remembered that all who had professed to receive the Gospel were not born of God: the parable of the Sower shows that. Intelligence might be informed, conscience searched, natural affections stirred, and yet there be "no root" in them. All is not gold that glitters. There has always been a "mixt multitude" (Ex. 12:38) who accompany the people of God. Moreover, there is in the real Christian the old heart, which is "deceitful above all things and desperately wicked", and therefore is he in constant need of faithful warning. Such, God has given in every dispensation: Genesis 2:17; Leviticus 26:15, 16; Matthew 3:8; Romans 11:21; 1 Corinthians 10:12.
Finally, let it be said that while Scripture speaks plainly and positively of the perseverance of the saints, yet it is a perseverance of saints, not unregenerate professors.
