So...you would place Paul on the dark side? Our earliest reference to Jesus position on divorce is in Paul, and he, after enunciated Jesus's rejection of divorce in the most absolute of terms ("Jesus says...") introduces his exception with "But I [Paul] say..."  

So the current magisterial position of indissolubility stands in stark contrast to Paul's application of the Amoris Laetitiae principle of mercy long before Francis.

Further,  in one of gospel text on indissolubility, adultery is proffered as an exception. And then there is the Petrine privilege. So within the traditional understanding of these scriptures, we have three exceptions, one from the mouth of Jesus, and two from the mouths of apostles. 

The Church was given the power to bind and loose; following the examples of Jesus, Paul, and Peter, why should she not use that power to expand on exceptions for pastoral reasons?

There are NO SCRIPTURAL GROUNDS for absolutism re divorce!
