19:1-3
Jesus then left for Judea. Large crowds continued to follow Him.The Pharisees continued to seek to trap Jesus. In the meantime Jesus had healed many people.The Pharisees asked if it was lawful for a man to divorce his wife for any reason.The background to this was Deut 24:1-4, where Moses said a man had to give a divorced wife a certificate.
19:4-8
Jesus points them back to the beginning in Genesis.God intended marriage to be lifelong. Now look at how different the interpretation of this verse by Jesus is, compared to that of the Pharisees. Jesus tells us that God gave this because “our hearts are hard”. He also says Moses “permitted” divorce. The Pharisees saw it as a command. So the ideal if 19:4-6 stands and is the guiding principle, the one we are to seek to live by. But because we are sinners sometimes divorce will happen, sometimes may even be necessary. So the Law was given to ameliorate the consequences, to give the wife some protection. The Pharisees saw it as a way of life! They saw divorce as part of the normal course of events. The sinful heart will twist every good law to evil purpose. We see this with secular laws, especially in the area of finance.
19:9
Jesus now tells us that “anyone who divorces his wife, except for adultery, and marries another woman commits adultery.” If we read this as a rule about divorce and remarriage we are missing the point. The liberal group on divorce, the “burn the toast” sect were doing this: If they fancied another woman, then they would give their current wife a certificate of divorce for some reason or other, then marry the other woman, claiming all the while to be following the Law of Moses and so they were a good Jew. Absolute nonsense, you are an adulterer, says Jesus. The human heart is deceitful above all things and will twist anything round to turn good into evil.
19:10-12
The disciples were, evidently, infected by the spirit of the age, seeming to think that the lifelong commitment of marriage was not such a good idea after all. How can two people possibly be happy together forever? We need to beware of being infected by the spirit of the age. “This teaching is not meant for everyone”. Jesus does not mean that marriage as a lifelong relationship is only applicable to some marriages. What He means is that not everyone will get married. He mentions some who were born eunuchs and some who were made eunuchs. Now this includes physical eunuchs, but I believe we can give it a wider application. There some for whom marriage may well be impossible for reasons from birth, disabilities of some sort or other (of course, not all disabilities make marriage impossible, far from it). For others the circumstances of life will just mean it never happens, sometimes for definite reasons, sometimes for no discernible reason, it just never happened. Then there will be those who renounce marriage for the sake of the kingdom.
I have written two longer discussions of the practical implications on Jesus’ teaching on divorce:
Mark 10:10-12 - Adultery and divorce - Part 1
Mark 10:10-12 - Adultery and Divorce - Part 2
