My convictions will go with me into marriage, despite the fact that I'm not Catholic. It's not moot. Opposing abortion at any stage in any way is never moot. This is not a religious mandate, it's my personal opposition to killing unborn babies even "some percent of the time"
There are unabortive methods, Disphragms, spermicides, condoms, sponges, film... So my opposition is not to your using birth control, it's using the killing kind.
Why choose the abortive kind for reasons other than convienence?
Ok, hypothetical situation.
Someone needs to take birth control, and has no other options. Yet she still wishes to have relations with her husband. What if she abstains on ovulation days (Catholics support the "rhythm method", and now you know which days these will be thanks to the pill), and also used other precautions, such as a condom or diaphragm? The pill would then never be an abortificant.
Is that ok?
The post was about birth control and child spacing. That was all. If you are not Catholic, you are morally able to use a condom.
