What does your religious/spiritual beliefs say about these three things? (Commitment as in commitment to a single partner)
Is commitment the middle way? Can celibacy be spiritually healthy? Can casual sex be spiritually detrimental? Why?
If your spiritual beliefs don't say anything, feel free to just give your opinion.
Different movements of Judaism have different slants on this, so I am only representing my own view, not that of all Jews.
What is licit is sex between a husband and wife. Anything else is sin. That's what I believe, and that's what I live in my life (I'm divorced and celibate).
I believe this is for the best of people, especially children.
1. Sex is extremely powerful -- it binds you to the other person. This is especially true for women in general. Are there exceptions? Of course. But we don't make recommendations on the basis of exceptions, we make recommendations based on what is the most good for the most people. The heartbreak is bad enough when you end things in a relationship with no sex -- it is devestating when you break off a relationship and you have had sex.
2. Women in general (with exceptions) have a much harder time than men with casual sex. There are of course men who do not want casual sex -- I am simply talking about the top of the bell shaped curve. This societal push for women to be as casual about sex as men are is, I believe, anti-women. Women should not need to become like men--we are fine the way we are.
3. Not only do all methods of birth control have a method failure rate (meaning sometimes they do not work even when used properly), the truth is that often times people do not use them properly. The result is that there are plenty of babies born in this world for couples who contracept. It is a given that the most ideal arrangement for children, all other things being equal (like that they are loved, etc.) is to be raised in a committed married home with both a father and a mother. For example, the single biggest factor for childhood poverty is for a child to be raised by a single mom. That doesn't mean that there aren't rich moms. Again, we are speaking to the top of the bell shaped curve. Children should not be deliberately brought into a family that is less than the ideal. Heck even if the couple is married, they will be imperfect, and may even divorce later. But the idea is to give children the best environment we can. In my view, therefore, doing things which can result in a pregnancy outside of marriage is abusive to children. It puts the selfish needs of adults above the care of children.
