I would like to say that, on the subject of divorce, Torah is explicit and quite permissive. If both husband and wife agree upon divorce, the divorce is granted with no sanction on either side. Beyond that, either husband or wife may seek a divorce for cause. Valid causes include spousal abuse, witholding (by either party) of conjugal satisfaction either as a means of control or as a result of loss of interest, participation in adultery by either partner, failure of the husband to provide sufficiently for the family, and many others. The major consideration in all of this is the disposition of the goods promised in the ketubah (marriage contract).
Looking at the treatment of divorce in Torah through the lens of Luke 16:18 distorts Torah badly. There is no foundation in Torah or Halacha (the distillation of Jewish Law from Torah) for such a pronouncement. If Jesus actually said those words, doubtful as he would have been well versed in the law, he was making it up out of whole cloth.
I bring this up because readers of your article might reasonably conclude that Jewish Law prohibits divorce, which is absolutely not the case. In fact, Jewish Law presents a more progressive and egalitarian treatment of divorce than has been seen in any other tradition, including purely secular law, prior to the past few decades. Your point is a good one, but I want to make sure that Christian distortion of Torah is not permitted to define Torah.
