Well, if we're gonna digress... :lol:
"Radical" in regard to "Big J" (Jesus) has been something I equate to His rock-stardom and accounts as such more than his approach, at least from what I gather. The guy was huge during, and obviously, after his just over three decade corporeal tour of terra-firma. He was doing something no one else had done. Saying things no one else had really said. He put together themes the needy, sick, poor and destitute appreciated, and gave them hope. He gave them faith in a time when the world needed it.
It's what he wasn't, to me, rather than what he was, that made him remarkable. He was rebellious. He was, to some, a heretic of current beliefs and process. He stood up when few others would, but did so in a peaceful manner rather than a violent one. He transcended human experience and produced with his life, and continues after death (and resurrection, if you're so inclined). Big J was punk rock personified, if you want a term we might both enjoy. He never let oppression or small numbers get to him, and he encouraged others to rise above and do what was necessary--even die.
He was love, personified. Many great teachers and men of the past were. Grand tyranny and grand love can both get some equal results control, stability, even hope--but love does more with less. Empathy, forgiveness, charity, and community come about in times when it is needed most, and Jesus was one of the pinnacles. It isn't what about He was, it was what he did...and what He did wasn't necessarily the answer: it's the content of His character that made the difference. Love is simply more efficient. Everything we do based upon it is a product. How we go about it is a natural enemy to this thing one might call "sin."
These are not new concepts. I find it interesting, though, more and more the "anti-sin," isn't as important as "pro-love" in more modern Christian directions.
This is a layman's assessment, but might be food for thought. *shrug*
