Why would it say if they should fall away.
The only way I can understand this is to be in agreement with pelican post#23.
Hebrews 6:1-2
[SUP]
1[/SUP]Therefore leaving the principles of the doctrine of Christ,
let us go on unto perfection;
not laying again the foundation of repentance from dead works, and of faith toward God, [SUP]
2 [/SUP]
Of the doctrine of baptisms, and of laying on of hands, and of resurrection of the dead, and of eternal judgment.
Read what is bolded in red especially carefully. This is about teaching christians. What is useful and what is not useful to teach.
Hebrews 6:4-6
[SUP]
4 [/SUP]For
it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost,
[SUP]
5 [/SUP]And have tasted the good word of God, and the powers of the world to come,
[SUP]
6 [/SUP]
If they shall fall away,
to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.
Would you say this is also a warning to not crucify the Son of God afresh and put Him to an open shame, or that it is impossible to crucify the Son of God again and put Him to an open shame?
There is no need to teach Christians Repentance because they already have repented. And if they did need to be taught they couldn't do it anyway, because its impossible.
You need to get into Hebrews 7,8,9,10 to see what is useful to teach to Christians.
Hebrews 7:24-28
[SUP]
24 [/SUP]But this man, because he continueth ever, hath an unchangeable priesthood.
[SUP]
25 [/SUP]Wherefore
he is able also to save them to the uttermost that come unto God by him, seeing he ever liveth to make intercession for them.
[SUP]
26 [/SUP]For such an high priest became us, who is holy, harmless, undefiled, separate from sinners, and made higher than the heavens;
[SUP]
27 [/SUP]Who needeth not daily, as those high priests, to offer up sacrifice, first for his own sins, and then for the people's: for this he did once, when he offered up himself.
[SUP]
28 [/SUP]For the law maketh men high priests which have infirmity; but the word of the oath, which was since the law, maketh the Son, who is consecrated for evermore.
