But dealing with reality isn't something religion does well.
The Church's job is to teach people how to live a moral life. Whether people are strong enough to follow the Church's teachings is irrelevant. Sex should be limited to marriage.
I haven't followed that personally in my life, and I've used plenty of contraception. That doesn't mean it's right, it just means I'm not a perfect human being.
I'm pretty sure the reason WHY the Catholic religion has no use of contraception in their religion as I stated earlier, that doesn't make it any less dangerous or wreckless when they apply it.
Unless of course you live in the unrealistic world where everyone waits to have sex until their married and there are no drugs in the world. Is that the case?
Myself and others live in the REAL world, where things have to be combated using REALISTIC means and contraception is one of them.
The belief that somehow having a packaged rubber balloon in your pocket ENCOURAGES people to have sex is ridiculous. The desire, will, and action is there without a piece of rubber.
The Church's job is to teach people to live a moral life. The fact that many people don't have the strength to do so doesn't change the Church's mission.
I have broken this rule myself and had sexual partners and I have used contraception. That doesn't mean the definition of morality changes. That just means I failed to live up to a higher standard.
