It is more than passing strange that Jesus, having reduced the prescriptions and proscriptions of the law to a three-fold command to love God, your neighbor, and yourself, should be resolutely ignored on this point (once the lip service has been paid), so believers can go back to poring over - and fighting over ... the prescriptions and proscriptions of the law. The strange emphasis placed by certain professed believers upon the mechanics of sex is sadly wondrous. Perhaps it has something to with our tendency, especially in this shallow, celebrity-laden era, to think of human love as something passive, something we "fall into." Whereas love is really something one does. It is, strictly speaking, benevolentia, the willing of another's good. This may sometimes mean placing another's good before one's own. That's when it starts to get hard.
