A clear and growing faith, in heavenly things was needed to preserve Jewish Christians from relapse. To return to Judaism was to give up Christ, who had left their house desolate (Matthew 23:38). It should be pointed out, however, that it is just as easy, and the attraction is just as real, for a Gentile Christian to return to that world out of which the Lord has called him, as it was for a Jewish Christian to go back again to Judaism.
In verse 4, For it is impossible for those who were once enlightened" the apostle continues the digression which he began at Hebrews 5:11. The parenthesis has two divisions: the first, Hebrews 5:11-14 is reprehensible; the second, Hebrews 6:1-20 is hortatory. In chapter 6 he exhorts the Hebrews unto two duties: to progress in the Christian course (verses 1-11); to persevere therein (verses 12-20). The first exhortation is proposed in verses 1,2 and qualified in verse 3. The motive to obedience is drawn from the danger of apostasy (verses 4-6). The opening "For" of verse 4 intimates the close connection of our present passage with that which immediately precedes. It draws a conclusion from what the apostle had been saying in Hebrews 5:11-14. It amplifies the "if" in verse 3. It points a most solemn warning against their continuance in their present sloth.
Three things claim our careful attention in coming closer to our passage: the persons here spoken of, the sin they commit, the doom pronounced upon them. In considering the persons spoken of it is of first importance to note that the apostle does not say, "us who were once enlightened", nor even "you", instead, he says "those". In sharp contrast from them, he says to the Hebrews, "Beloved, we are persuaded better things of you".
It is scarcely accurate to designate as "mere professors" those described in verses 4,5. They were a class who had enjoyed great privileges, beyond any such as now accompany the preaching of the Gospel. Those here portrayed are said to have had five advantages, which is in contrast from the six things enumerated in verses 1, 2, which things belong to man in the flesh, under Judaism. Five is the number of grace, and the blessings here mentioned pertain to the Christian dispensation. Yet were they not true Christians. This is evident from what is not said. Observe, they were not spoken of as Gods elect, as those for whom Christ died, as those who were born of the Spirit. They are not said to be justified, forgiven, accepted in the Beloved. Nor is anything said of their faith, love, or obedience. Yet these are the very things which distinguish a real child of God. First, they had been "enlightened". The Sun of righteousness had shone with healing in His wings, and, as Matthew 4:16 says, "The people which sat in darkness saw great light, and to them which sat in the region and shadow of death light is sprung up". Unlike the heathen, whom Christ, in the days of His flesh, visited not, those who came under the sound of His voice were wondrously and gloriously illumined.
The Hebrews had accepted the gospel of the once crucified and now glorified Redeemer, who sent down from heaven the Spirit, a sign of His exaltation, and a pledge of the future inheritance. Having thus entered into the sphere of new covenant manifestation, any one who willfully abandoned it could only relapse into that phase of Judaism which crucified the Lord Jesus. There was no other alternative for them, but either to go on to the full knowledge of the heavenly priesthood of Christ, and to the believers acceptance and worship through the Mediator in the sanctuary above, or fall back into the attitude, not of the godly Israelites before Pentecost, such as John the Baptist and those who waited for the promised redemption, nor even into the condition of those for whom the Savior prayed, for they know not what they do; but into a state of willful conscious enmity against Christ, and the sin of rejecting Him, and putting Him to an open shame" (Adolph Sophir)
Now I dont believe that a true believer can fall into apostasy either. The stress is on true believers. And the people spoken of in Hebrews 6:4-6 were not true believers.
First, 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. 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. 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.
Fourth, "And have tasted the good Word of God". "I understand by this expression the promise of God respecting the Messiah, the sum and substance of all. It deserves notice that this promise is by way of eminence termed by Jeremiah that good word (Jer. 33:14). To taste, then, this good Word of God, is to experience that God has been faithful to His promise. They could not say with Jeremiah, "Thy words were found and I did eat them" (Jer. 15:16). "Itis as though he said, I speak not of those who have received nourishment; but of such as have so far tasted it, as that they ought to have desired it as sincere milk and grown thereby" (Dr. John Owen). A solemn example of one who merely "tasted" the good Word of God is found in Mark 6:20: "for Herod feared John, knowing that he was a just man and an holy, and observed him; and when he heard him, he did many things, and heard him gladly".
Fifth, "And the powers of the world to come," or "ageto come." The reference here is to the new dispensation which was to be ushered in by Israels Messiah according to Old Testament predictions. It corresponds with "these last days" of Hebrews 1:2, and is in contrast from the "time past" or Mosaic economy. These "powers" of the new Age are mentioned in Hebrews 2:4, to our comments on which we would refer the reader. Of these mighty "powers" these apostates had "tasted",or had an experience of. They had been personal witnesses of the miracles of Christ, and also of the wonders that followed His ascension, when such glorious manifestations of the Spirit were given. Thus they were "without excuse". Convincing and conclusive evidence had been set before them, but there had been no answering faith in their hearts. A solemn example of this is found in John 11:47, 48. The class here described are such as had had their minds enlightened, their consciences stirred, their affections moved to a considerable degree, and yet who were never brought from death unto life. Nor is it backsliding Christians who are in view. It is not simply "fall into sin",this or that sin. The greatest "sin" which a regenerated man can possibly commit is the personal denial of Christ: Peter was guilty of this, yet was he "renewed again unto repentance". It is the total renunciation of all the distinguishing truths and principles of Christianity, and this not secretly, but openly, which constitutes apostasy.
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).
"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.
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.
