Apologies for the title - I'm just having a little fun with those who think John Calvin is part of the unholy trinity of Satan, the Antichrist, and John Calvin and the totally reformed brethren of mine who almost want to revert to Rome so they can canonize St. John of Calvinism...Anyway, I am actually a fan.
Our church is teaching through the book of Hebrews and I found Calvin's commentary on Hebrews 6 to be quite helpful.
If any one asks why the Apostle makes mention here of such apostasy while he is addressing believers, who were far off from a perfidy so heinous; to this I answer, that the danger was pointed out by him in time, that they might be on their guard. And this ought to be observed; for when we turn aside from the right way, we not only excuse to others our vices, but we also impose on ourselves. Satan stealthily creeps on us, and by degrees allures us by clandestine arts, so that when we go astray we know not that we are going astray. Thus gradually we slide, until at length we rush headlong into ruin. We may observe this daily in many. Therefore the Apostle does not without reason forewarn all the disciples of Christ to beware in time; for a continued torpor commonly ends in lethargy, which is followed by alienation of mind.
But we must notice in passing the names by which he signalizes the knowledge of the Gospel. He calls it illumination; it hence follows that men are blind, until Christ, the light of the world, enlightens them. He calls it a tasting of the heavenly gift; intimating that the things which Christ confers on us are above nature and the world, and that they are yet tasted by faith. He calls it the participation of the Spirit; for he it is who distributes to every one, as he wills, all the light and knowledge which he can have; for without him no one can say that Jesus is the Lord, (1 Corinthians 12:3;) he opens for us the eyes of our minds, and reveals to us the secret things of God. He calls it a tasting of the good word of God; by which he means, that the will of God is therein revealed, not in any sort of way, but in such a way as sweetly to delight us; in short, by this title is pointed out the difference between the Law and the Gospel; for that has nothing but severity and condemnation, but this is a sweet testimony of God’s love and fatherly kindness towards us. And lastly, he calls it a tasting of the powers of the world to come; by which he intimates, that we are admitted by faith as it were into the kingdom of heaven, so that we see in spirit that blessed immortality which is hid from our senses.
Let us then know, that the Gospel cannot be otherwise rightly known than by the illumination of the Spirit, and that being thus drawn away from the world, we are raised up to heaven, and that knowing the goodness of God we rely on his word.
But here arises a new question, how can it be that he who has once made such a progress should afterwards fall away? For God, it may be said, calls none effectually but the elect, and Paul testifies that they are really his sons who are led by his Spirit, (Romans 8:14;) and he teaches us, that it is a sure pledge of adoption when Christ makes us partakers of his Spirit. The elect are also beyond the danger of finally falling away; for the Father who gave them to be preserved by Christ his Son is greater than all, and Christ promises to watch over them all so that none may perish. To all this I answer, That God indeed favors none but the elect alone with the Spirit of regeneration, and that by this they are distinguished from the reprobate; for they are renewed after his image and receive the earnest of the Spirit in hope of the future inheritance, and by the same Spirit the Gospel is sealed in their hearts. But I cannot admit that all this is any reason why he should not grant the reprobate also some taste of his grace, why he should not irradiate their minds with some sparks of his light, why he should not give them some perception of his goodness, and in some sort engrave his word on their hearts. Otherwise, where would be the temporal faith mentioned by Mark 4:17? There is therefore some knowledge even in the reprobate, which afterwards vanishes away, either because it did not strike roots sufficiently deep, or because it withers, being choked up.
And by this bridle the Lord keeps us in fear and humility; and we certainly see how prone human nature is otherwise to security and foolish confidence. At the same time our solicitude ought to be such as not to disturb the peace of conscience. For the Lord strengthens faith in us, while he subdues our flesh: and hence he would have faith to remain and rest tranquilly as in a safe haven; but he exercises the flesh with various conflicts, that it may not grow wanton through idleness.John Calvin, Commentary on Hebrews,

Overall, I find those with a covenantal and communitarian view of the gospel to have much less difficulty with the language of the warning passages of Hebrews...particularly those of Hebrews 6 and Hebrews 10. I somewhat straddle the covenantal view of the community and the Baptist view of a believing church...so these passages can be tougher for me.
I like the reformed view that the visible covenant community is a mingled mass of people both regenerate and unregenerate. In such even the unregenerate person in the community is tasting, seeing, experiencing, etc. yet remains unregenerate. These warnings then have full force when directed "at the people in the community" - yet are only actual possibilities for some. Big box is the whole people, little box are regenerate, the warning aimed at all, only possible for some.
What do you think? Maybe Mark Dever can be of help for the reformed Baptist types who feel a bit in a pickle between the clear covenantal view and the mistaken Arminian view of the actual apostasy of regenerate believers...
