"That is why the command is do not lean on your own understanding and do not trust nobles or the sons of men (who wrote the Bible)."
If you can't trust the bible how would you know that the "angel from heaven" was preaching a gospel other than the one.......?
"That is why the command is do not lean on your own understanding..."
How do you know that command is from God if you can trust the bible? Isn't the bible where you first learned of the command?
