I don't understand how they can just skim over Jesus refusing to obey the Sabbath laws to care for a person.. that sets a clear precedent right there. Aren't we supposed to follow by Jesus example? So the excuse "Well Jesus can do anything he wants" is not a valid one. Jesus was here to set an example, and his example was that it is wrong to sacrifice life for law.
I guess the more you push, the more he will defend, even up to a ridiculous point and then all you can do is feel sorry for the man and continue on..
