psr.2,
I, too, would welcome serious debate as to the meanings and implications of various bible passages. But, alas, this thread is not one. Thus far you have berated and insulted everyone who disagreed with you. That, I am afraid to tell you, is not debate (no matter what the presidential candidates say).
From what I have learned, the book of Hebrews was written to three audiences. One, those Jews who had accepted Jesus Christ as Savior and Messiah. Two, those Jews who agreed intellectually witht he gospel, but did not yet believe. Third, those Jews that rejected Jesus Christ as Savior and Messiah.
The passage in question:
For it is impossible to restore again to repentance those who have once been enlightened, who have tasted the heavenly gift, and have shared in the Holy Spirit, and have tasted the goodness of the word of God and the powers of the age to come, if they then fall away, since they are crucifying once again the Son of God to their own harm and holding him up to contempt.
Hebrews 6:4-6 ESV
is one of those that is pointed at the second group of Jews.
I also realize that you want to avoid a 'version issue', but by disallowing the examination of the underlying Greek, you are making it one.
In CHrist,
Trotter
