First of all, what the hell is wrong with this hypothetical woman if her first husband finds her to be unclean and her second ends up detesting her? Did they uncover some crazy spring break photos of her on the internet?
Second of all, why would god find a need to specifically draw attention to such a rare instance of a woman’s second husband dying and her choosing to return to her first husband?
Either way, it is there, clear as a summer day: “and he writes her a certificate of divorce”. So divorce is OK, right? Wrong! This is just another one of those tricks that god likes to play on people to keep himself entertained. Or, at least that’s what Jesus says:
“The Pharisees came and asked Him, “Is it lawful for a man to divorce his wife?” testing Him. And He answered and said to them, “What did Moses command you?” They said, “Moses permitted a man to write a certificate of divorce, and to dismiss her.” And Jesus answered and said to them, “Because of the hardness of your heart he wrote you this precept. But from the beginning of the creation, God ‘made them male and female.’‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh’; so then they are no longer two, but one flesh. Therefore what God has joined together, let not man separate.” In the house His disciples also asked Him again about the same matter. So He said to them, “Whoever divorces his wife and marries another commits adultery against her. And if a woman divorces her husband and marries another, she commits adultery.” Mark 10:2-12
Well, which is it? Can we divorce or can’t we? If I want a divorce I can certainly find a verse that says it is OK, (I just can’t remarry my first husband if my second one dies, AND, since I am a mere woman, I can’t be the one to make that decision, it has to come from my husband) but if I don’t, I can certainly find a verse in the Bible that says it is not OK.
This is the problem with the Bible (among infinite other things). I can find any excuse in any verse in the Bible to justify why I said or did something and why I feel the way I do. In fact, I can change my mind from day-to-day it’s OK! It’s in the Bible!
