I’m a protestant, and I oppose contraception. The world should have listened to Pope Paul VI.
Bump
I once had a long car ride with a Unitarian-Universalist gal (to be fair, she had been brought up Catholic) wherein for hours we talked back and forth about the morality of contraception.
We both persisted in this converstion through sunshine and snowstorm, hour after hour, because we both believed that IF it is true that contraception is morally objectionable, it MUST be something rooted in Natural Law, i.e. what is right and fitting for us as human beings, discernible by reason guided by good will.
So we we weren't just talking about Onan. We were talking about the whole consequences of a wholly Onanistic mentality and culture.
We came to the the conclusion that contraception really launched our society off in the wrong direction, It is a choice against the normal and in favor of the subnormal. It is a choice against whole sex in favor of fragmented, functionally impaired sex. It is a thread which, if you cut it and then start pulling it out, necessarily unravels the whole sweater.
I wish I could remember that whole conversation. (It was years and years ago.) I really think everybody could figure this out, if they looked deeply enough into how God's design works --- how all the threads are connected.
I know of a Protestant minister who had his vasectomy reversed when he realized how much God hated contraception. His wife promptly gave birth to two more children within just a few years. He in turn is encouraging others to do the same.
