1. either God is a God who must be seen in legalistic terms or
2. a God of love who sometimes sets law aside when the call of love supersedes.
There are also political and money issues behind the Pharisees but Luke focuses on the Law. Jesus understands the Law in its deeper, more complete meaning and thus is able to show the stupidity of the Pharisees' thinking; they would untie a donkey on the Sabbath, but they would not untie a woman bound up by Satan. Sometimes we still think the same way ourselves!!!!!
