the nature of sin

[Gwaithmir]

Sin is nothing more than a priestly construct designed to control people through fear and guilt. 

ah, no. Sin link to morality only represents 1/3 of what sin is. when look at as a whole sin is a completely different construct.

When you are prepared to prove that:

1. God exists;
2. That Jesus was the son of God;
3. That the Bible tales of Jesus are true;

....THEN, and only then, can you discuss your befuddled hypothesis of how sin should be defined.  Good luck with that.
