6 if they fall away, to renew them again to repentance, since they crucify again for themselves the Son of God, and put Him to an open shame.
crucify again for themselves the Son of God,
“For themselves” means on their own account. The readers must take full responsibility for what they have done. The reason these Christians cannot be renewed again to repentance is that they reject the finished work of Christ on the cross. This is to trod under foot the cross of Christ (He 10:29). The readers were in the process of doing this at the time of writing Hebrews (present participle).
To re-crucify Christ by going back to Levitical sacrifices is what keeps people from being renewed again to repentance. These people repudiated Christ’s finished work on the cross by going back to Old Testament sacrifices, which never completed the payment for sins.
and put Him [Christ] to an open shame.
Crucifying Christ again by going back to Levitical sacrifices puts Him to public shame. This would imply that His finished crucifixion was incomplete. He would have left something undone. Those who do this would reaffirm Judaism. It is a disgrace to claim that Jesus’ crucifixion was not final but that one needs their sins forgiven again and again.
The coordination of “crucify again” and “put Him to open shame” is the dual condition whereby it was impossible for the readers to enter repentance. So long as they are in this condition the impossibility remains. If they stop these conditions, then they can be restored to fellowship. Hebrews 6:9-12 shows that the author is speaking about Christian restoration, not salvation itself.
Our attitude toward God’s Word determines our attitude toward Christ.
We cannot divorce the living Word from the written Word. Without the written Word we cannot formulate God’s principles for living. Without these values we will remain stuck in reversionism in our life. Otherwise, we will drift from the truth (He 2:1-4).
