It is mighty curious how certain so-called experts in God's law claim that God's law is as perennially binding in 2017 as it must have been in 17 AD, or even in 17 BC or years prior!   It's more than enough to make any reasonable person realize that these "experts"  do not understand law or the nature os law (including God's law) or human sexuality!  And the Catholic hierarchy has has plenty of opportunities to update itself, but has chosen not to do so.  Wonder if all that could have something to do with the clergy sex abuse crisis, as well as defective seminary formation!
