You say, He was about turning us in a different direction, away from the direction of line drawing and toward being more responsive to the Spirit within.”
But Jesus himself drew lines and ratified old ones. It was certainly an act of line-drawing when he said, “What therefore God hath joined together, let not man put asunder.”  How do you get from “let no man put asunder” to “It’s Ok for man to put asunder the marital bond.”?  You can move away from line-drawing all you want, and be more responsive to the Holy Spirit than any saint, and still not convert what Jesus said into its opposite.
As for taking Jesus' words on divorce literally:   Ask yourself whether there is a sensible metaphoric meaning, and whether this, rather than the literal reading, is more likely what Jesus intended.  I submit there is no metaphoric meaning that Jesus was more likely to have intended than his literal meaning.  You cannot get there from here, from "Do not divorce" to "Divorce is OK."
