Communities in Mississippi are using the Bible to reject any sex education other than abstinence. Interestingly, Mississippi's divorce rates are among the highest in the country, and by region the South has the highest rate.
Jesus didn't hand out many laws. He taught by parable and the example of his actions. However, Jesus spoke clearly about divorce: In the Gospel of Mark, he said: "Anyone who divorces his wife and marries another woman commits adultery against her. And if she divorces her husband and marries another man, she commits adultery."
It seems that Mississippi's adherence to biblical law, which I'm not encouraging, extends to sex education, for which I can't find any specific law. But Mississippi doesn't do the same on divorce.
This is just another example of using the Bible when it says what you want it to say.
What God has joined together, let no man put asunder.
So, sex is a dirty, shameful, disease-causing act — that you save for the one you marry.
