Why did Jesus say the Son of Man was Lord over the Sabbath because the Sabbath was made for man? Then he said to them, “The Sabbath was made for man, not man for the Sabbath. So the Son of Man is Lord even of the Sabbath.” (NIV Mark 2:27-28)


There seems to be a connection with the Sabbath being made for 'any man' and from this proposition, 'the Son of Man' , that is the second Adam, has all the more right to change the Sabbath, or at least at a minimum use it as it was intended to the first Adam, if he so chooses.

I sense an argument here but can't immediately find the words for it.  Has anyone heard of a good explanation? I looked up a couple commentaries but nothing seemed to be that good at all.
I think you are getting hung up on Son of Man being a divine title. We take it as that, but it doesn't mean that fundamentally. It means something along the lines of the Ideal Man, the Best Man, the Representitive Man. It doesn't imply divinity.

Jesus' point then is that the Sabbath was created for the good of people. That's how the CEV translates it. JB Phillips translates it "for the sake of man". In other words the purpose of Man is not to keep the Sabbath - the purpose of the Sabbath is to keep Man operating as (s)he should.

Because of this, Jesus is saying, if the rules of the Sabbath are actually getting in the way of people doing the right thing, then they should be changed and Man has the power to do that. It should of course be noted that the precise details of what was permitted on the Sabbath were not direct commands of God; the violation was only of the current interpretation of what constituted Sabbath-breaking.
