“... people who prefer to pretend they’re under no obligation to Christ to obey Christ in order to be obedient to Christ.” That would be a terrible position to be in without God’s Life in one, eh? If I am under the 600+ laws of sin and death and fail to keep them all, I am guilty as if I have violated them all.
Well, if you're a Pharisee you count all those laws as laws you must obey and if you're not a Pharisee, then what Christ Himself tells us is required is all that is required.
Having not placed the Pharisee Rabbis of Jamnia above the Holy Spirit, I don't worry about those 600 laws and I'm sure "reformed" Jews don't much care for what Pharisee Rabbis have to say, either.
That leaves only those who insist that Pharisee Rabbis are led by God but that the Holy Spirit is not. No doubt such folks are rather desperate to come up with some way to pretend they're not bound by such laws and for such folks I'm sure one fantasy is as good as another.
