Here is an interesting look at two entirely different "packages" and where they lead to...
The person who wrote it is opting for Package number two which of course is the unbiblical one...
"There doesn't seem to be any question that the definition of sin, and the nature of Christ, and perfectionism are a package. I think the contention is quite valid that if a person defines sin primarily in terms of transgression of the law-in legalistic terms and understandings-then he is going to need to have a savior who has struggled with all of his same temptations to transgress the law. In the process one ends up with perfectionism and a behaviorally oriented Christianity.
"Now if you go back to define sin in terms of living a life apart from God -you don't need to have a Savior exactly as you are. In fact, His very difference indicates that He could have lived independently, but He chose to depend on God. I feel that His dependence upon the Father is the essence of Christ's example to us. After all, He did say, 'Without Me, you can do nothing.' Allowing a difference between our nature and Christ's nature prevents us from getting bogged down in perfectionism, because that's not where the issue lies, anyway. Perfection of character must be seen in terms of relationship, not in terms of spelling out ethical and moral options." MV, Insight Magazine
