Are Roman Catholics expected to never use contraception/artificial birth control in any circumstance whatsoever?
The only exceptions I've heard of are:
1. Health issues, where women's lives are at stake because of pregnancy.
2. With the permission of one's parish priest after showing that they are not opposed to having children (Nancy Pelosi had 5 kids and I believe claimed that after that she was allowed to use birth control).
The second proposition probably isn't true, but I'd heard it so I figured I'd ask for clarification.
I know so many Catholics who only have 1 or 2 kids but seem to be devout in all other areas, so I don't know if there are exceptions, or if that is just one of those things that everyone just constantly confesses, and still does anyway.
