procreation

[Raymott]

I'd have a lot to add. I'd be breaking the rules then, so it's better to pass.


I.

A wise move I think

[sky753]

The position of the Vatican is that unless you are attempting to become pregnant (or impregnate your wife), you should abstain from sex.
The function of sex is procreation, not for fun or to express love or any other reason.
If you do have sex, and God intends for a pregnancy to occur, it is not your right to try to prevent it - which is what a condom does. Using a condom is frustrating God's will.
The prevention of HIV is simple: a virgin male marries a virgin female, and they remain faithful to each other.
Anyhow, that's the argument. I don't subscribe to it myself, and logically it seems quite easy to refute, but millions (billions?) of Catholics are required to believe if.

A valuable backgound helps us to comprehend the passage! Thanks!
