I apologize that so many of the words ran together on that last post. I posted that from some old teaching outlines of mine. Perhaps the font was incompatible. Here is a better copy.
A. The prior state of those under discussion is that theyhad:
1. Been enlightened.
2. Had tasted the heavenly gift. (The word for tasted is γευσαμένους(geusamenous) which means to experience. This is the same word that is used in2:9 where it speaks of Jesus having "tasted" death for everyone. Thisis not a mere limited sampling, this is an embracing of the full experience.
3. Been made partakers of the Holy Spirit. These had received the indwelling ofthe Holy Spirit who serves as the Christian's seal of divine ownership.
4. Tasted the good word of God. Again the same word as in verse 4, γευσαμένους.
B. Present state - They have "fallen away."From what then had they fallen?
1. An enlightened state.
2. The experience of the heavenly gift.
3. The partaking or sharing of the Holy Spirit.
4. The good word of God.
5. They had crucified Christ all over again. Like those of 10:26-31, these had "trampledunder-foot the Son of God and regarded as unclean the blood of the covenant bywhich he WAS sanctified" (past tense). In other words, thesehas come to regard the blood that had once sanctified them as nothing more thanthe proverbial hog slaughtered on the altar.
C. The impossible dilemma - It is now impossible to renew them again torepentance. Why? Because they have fallen away from the very thing that broughtthem to repentance in the first place which was the word of God. It is nowimpossible to restore them to repentance. One cannot be RE-newed AGAIN to astate they have never occupied. Thus, having once been saved and then havingfallen away, they cannot be brought back because they will no longer repent.This is of course representing the extreme case.
D. Their fate.
Like the ground that yields thistles and thorns, they are cursed and they endup being burned. Just like those of 10:26-31, whose fate is to fall into thehands of a vengeful God who says, "I will repay."The parabolic illustration come out of Matthew 13:20-21, Mark 4:16-17, and Luke8:13. They had become worthless to the purposes of God and God discarded them.
1. The writer is not saying that these claimed to have tasted but presents asimple statement of fact - "They had tasted."Having once shared in the fellowship of Christ these had later abandoned Christand returned to the law. These had previously left the law in response to thegospel. Now, they are rejecting the cross and going back to the law. This isthe foundation they were "laying again."
2. This is not a question. There is no "if" in the Greek. It simplysays, παραπεσόντας (parapesontas) - literally "havingfallen away". This is a statement of fact basedon actual cases, not a what if scenario. This is an aorist, passive, accusativeverb. They had fallen away at some time in the past and that conditioncontinues. They are still fallen away. This is the force of the aoristaccusative case. At some point in the past they had fallen away - punctiliaraction irrespecrtive of the amount of time involved, and they remain fallenaway. Their condition has not changed.
3. Under the law, sin was not forgiven based on those sacrifices, but based ofwhat those sacrifices represented - the cross. Leviticus chapters 4 and 5 showus that sin was indeed forgiven under the law but, it was not by the law. EvenDavid understood this. "How blessed is the man whose transgressionis forgiven, whose sins are covered...to whom the Lord does not imputeiniquity," Psalms 32:1-2. He also knew thosesacrifices were not the avenue through which forgiveness came. "Thou dostnot delight in sacrifice or I would bring it."Psalms 51:1-2.
4. The inability to renew again is not linked to a supposition of"IF" they were to fall away. The impossibility is linked to the factthat after having been saved they had rejected the cross, not the oldsacrifices, and in so doing had shamed Christ openly and defiantly.
5. The writer does not say they could not be saved again. He says that cannotbe brought back to repentance again. This certainly renders them unable to remainsaved since there is no longer repentance. These had once been in a savedrelationship. Now that relationship has been severed; not by Christ but bythem.
6. He is not comparing the crucifying of Christ again to the repetitiousoffering of O.T. sacrifice. Those who had rejected and fallen away wereconsidering Christ worthy of the crucifixion. They were rejecting him and hissacrifice. Like those of 10:29, they were considering the blood of Christ "BYWHICH THEY HAD BEEN SANCTIFIED" an uncleanthing, and had insulted the Spirit of grace.
7. The writer's point is that these had been sanctified - made holy - A stategiven only to the saved, something that all of the sacrifices of the O.Tcombined could never do. In verse 29, he even draws a contrast between theone's of whom he is speaking and those who died under the law for rejectingMoses. They rejected the blood after having been cleansed by it and are nowworthy of greater punishment than those who were under the Law. Verse 30 showstheir fate. The Hebrew writer describes both the prior and latter states ofthose who had fallen away.
