Hebrews 6:6

If--Greek, "And (yet) have fallen away"; compare a less extreme falling or declension, Gal 5:4, "Ye are fallen from grace." Here an entire and wilful apostasy is meant; the Hebrews had not yet so fallen away; but he warns them that such would be the final result of retrogression, if, instead of "going on to perfection," they should need to learn again the first principles of Christianity (Heb 6:1). to renew them again--They have been "once" (Heb 6:4) already renewed, or made anew, and now they need to be "renewed" over "again." crucify to themselves the Son of God--"are crucifiying to themselves" Christ, instead of, like Paul, crucifying the world unto them by the cross of Christ (Gal 6:14). So in Heb 10:29, "trodden under foot the Son of God, and counted the blood of the covenant, wherewith . . . sanctified, an unholy thing." "The Son of God," marking His dignity, shows the greatness of their offense. put him to an open shame--literally, "make a public example of" Him, as if He were a malefactor suspended on a tree. What the carnal Israel did outwardly, those who fall away from light do inwardly, they virtually crucify again the Son of God; "they tear him out of the recesses of their hearts where He had fixed His abode and exhibit Him to the open scoffs of the world as something powerless and common" [BLEEK in ALFORD]. The Montanists and Novatians used this passage to justify the lasting exclusion from the Church of those who had once lapsed. The Catholic Church always opposed this view, and readmitted the lapsed on their repentance, but did not rebaptize them. This passage implies that persons may be in some sense "renewed," and yet fall away finally; for the words, "renew again," imply that they have been, in some sense, not the full sense, ONCE RENEWED by the Holy G…

In this chapter the apostle proceeds to persuade the Hebrews to make a better proficiency in religion than they had done, as the best way to prevent apostasy, the dreadful nature and consequences of which sin he sets forth in a serious manner (Heb 6:1-8), and then expresses his good hopes concerning them, that they would persevere in faith and holiness, to which he exhorts them, and sets before them the great encouragement they had from God, both with respect to their duty and happiness (Heb 6:9 to the end).

6:6 then turn (or fall) away: The image is reminiscent of the wilderness wanderers who turned away from obeying God and fell in the desert (3:17; 4:11; Num 14:1-4, 29-30). • to bring such people back to repentance: They had repented before, but had no fruit from their repentance (Heb 6:7-8). When people turn their back on Christ and his superior sacrifice, it is impossible for them to find any other means of repentance. • Rejecting the Son of God constitutes nailing him to the cross once again. Crucifixion was the ultimate instrument of rejection and humiliation in the Greco-Roman world and brought public shame. Those who turned away from Christ had in effect joined those who stood before the cross shouting insults, insisting that Jesus was not really the Messiah and Son of God but was instead worthy of shame (see Matt 27:39-44).
