I can see the element of legalism in it.
Here's my followup post, incase you missed it. Wish I could add this to my original post, but no option for that....
The subject is spiritual immaturity
......
Chapter 5:12-14: "For though by this time you ought to be teachers,
you need someone to teach you again the first principles of the oracles of God; and you have come to need milk and not solid food. For everyone who partakes only of milk is unskilled in the word of righteousness, for he is a babe. But solid food belongs to those who are of full age, that is, those who by reason of use have their senses exercised to discern both good and evil.
V1-3: "Therefore,
leaving the discussion of the elementary principles of Christ, let us go on to perfection,
not laying again the foundation of repentance from dead works and of faith toward God, of the doctrine of baptisms, of laying on of hands, of resurrection of the dead, and of eternal judgment. And this we will do if God permits"
After this comes verse 4 in my quote: "
For it is impossible..." (the "for" being a conclusion)
Connection here between elementary principles, the going on and on again about the foundation of repentance...... and then it goes on to confirm
an elementary principle that I mentioned in my quote - the impossibility of being saved, unsaved, then saved again (impossible to be renewed again when already renewed) - this is elementary!!
Can anyone else see all of this. He is talking to believers here.
So yes - eternal security is an elementary principle!!!!!!!!
