 For it would have been better enlightened, and have tasted the heavenly gift, and have become sharers in the Holy Spirit, and have tasted the good Word of God and the powers of the coming age, and have fallen away to renew them again to repentance, thereby crucifying the Son of God again, for themselves, holding Him up to contempt. You cannot crucify again unless you have crucified at least once already. For someone to crucify Jesus again must mean that he has indeed taken advantage of the first crucifixion, he was indeed savedif he was never really saved he never really appropriated the first crucifixion, so he cannot do it again. I have used to really know to translate the heightened form επιγινωσκω in contrast to γινωσκω, to know and real knowledge to translate the heightened form επιγνωσις in contrast to γνωσις, knowledge. I consider that the Holy Spirit is an intelligent and honest user of human language, so His choice of the heightened forms was deliberate. Those who seek to arrive at the intended meaning of the Text need to respect that deliberate choice. When Peter says someone has a real knowledge of the Lord and Savior Jesus Christ, that someone must be saved. To elevate a doctrinal system above the Word of God is a form of idolatry. for them not to have really known the way of the righteousness, than having really known it to turn back from the holy commandment delivered to them.
