You're right, I left that out. But you do so with the knowledge that becoming pregnant is a possiblity and you you don't use anything that would thwart that act.
The Church does allow certain things that would thwart procreation, though:
- natural phenomena like menopause and infertility - the Church doesn't ask for post-menopausal married women to stay celibate, does it?
- certain types of actions intended to prevent conception - e.g. the rhythm method/"Natural Family Planning".
I'm not really sure why the Church frowns on spatial barriers (e.g. a condom, which places
a physical divide between the egg and sperm), but not temporal barriers (e.g. NFP, which places
a span of time between the egg and sperm).
That's the thing. They are not imposing it on anyone. They are voicing their opinion. It's just the same as almost any other Christian religion.
There's one big difference I see: in the Catholic Church, the Church itself claims authority over its membership. In most Protestant denominations, the minister is viewed (hopefully) as a wise person who should be respected, but with no more authority than any other person.
How? By saying we don't agree with this? This is imposing their beliefs on others? Someone can tell me that they don't believe in God, they are voicing their opinion but I don't think they are trying to impose their beliefs on me.
Analogy time:
- saying "I don't believe in God" is
not an imposition of beliefs.
- saying "take down your crucifix"
is an imposition of beliefs.
- saying "I think condoms are wrong" is
not an imposition of beliefs.
- saying "keep the price of condoms high"
is an imposition of beliefs.
