“If they shall fall away, to renue them againe vnto repentance: seeing they crucifie to themselues the Sonne of God afresh, and put him to an open shame.”
1611 King James Version (KJV)
6:6 And have fallen away - Here is not a supposition, but a plain relation of fact. The apostle here describes the case of those who have cast away both the power and the form of godliness; who have lost both their faith, hope, and love, #Heb 6:10|, &c., and that wilfully, #Heb 10:26|. Of these wilful total apostates he declares, it is impossible to renew them again to repentance. (though they were renewed once,) either to the foundation, or anything built thereon. Seeing they crucify the Son of God afresh - They use him with the utmost indignity. And put him to an open shame - Causing his glorious name to be blasphemed.
Heb 6:6 If they shall fall away. Apostasize from the faith. To renew them unto repentance. He is so far fallen that he has no capacity left for repentance. Judas the Apostate sorrowed, but his sorrows became despair. There was remorse but not repentance. Seeing they crucify to themselves the Son of God afresh. By rejecting Christ they place themselves with those who rejected him and crucified him because he affirmed that he was the Son of God. Those meant are not those "overtaken in a fault" (Ga 6:1), or backsliders only, but men once Christian professors who not only turn away from but oppose Christ.
