We share that desire.  Twenty first thinking includes the influence of quantum science.  The Church is not noted for including current science in their traditional self affirming theology.  

I do want to commend you for your observation about Jamie's social science take vs revelation.  After some time to think about it, I think your point was passed off too easily given the prominence given biblical quotes by defenders of tradition.  I doubt those defenders are open to accepting current biblical scholarship which situates the Bible in historical/anthropological analysis.  To think that particulat mindset, clergy or laity, is willing to accept a view of homosexuality that includes epigenetics is folly at this point.  It will take a succession of popes to make much of current scientific reality a true reality for inclusion in natural law theology.  It's too bad people can't see, touch, taste, or feel, quantum dynamics, it might impact their view of reality.
