Birth control or contraception is against the divine law and natural law and no human law can trump the divine or natural law. Such a law is an evil and really no law at all and certainly not good for the human race and each person’s end and eternal destiny.
Unfortunately, not every one believes in God or the God of Christianity nor do all people agree on what the natural law specifies or even if there is a natural law although the natural law can be derived by the natural light of reason. Being that God created human beings with free will, he doesn’t force people to believe in Him so we can’t force the faith on people against their will although we ought to catechize and evangelize as Jesus commissioned us at the same time respecting people’s freedom as God created us.
In a democratic society such as the U.S.A., the state is by the people and for the people. The people also elect representatives to represent them in running the government. Our kind of government seems to be the best kind of government respecting and protecting the people’s individual freedoms and what not. So, let’s say the question comes up on whether birth control or contraception should be made legal or not. Well, according to our system of government, the people themselves probably ought to decide by vote, the majority vote winning I suppose. Personally, I wouldn’t vote for it of course and neither would I if I was an elected representative of the state. People generally know the views of the representatives before they elect them and which I would express, for example, if I made a run to be a representative. If you vote for me, your going to have a good idea of what I vote for concerning legislative laws in congress.
In conclusion, I personally could not in good conscience vote to pass a law that is against the divine law which I believe is only detrimental to human society, their happiness, and eternal salvation. It would entail formal cooperation in sin even if I never used contraceptives or believed they should not be used. But, God has not appointed me to rule over all other human beings and force my belief as it were on them. Accordingly, it seems to me as I said, it should be decided by the people in a vote. And if by majority vote contraception was made legal say, I still wouldn’t consider this absolutely lawful as it is against the divine law so such a law should not be forced on the people in a way that would go against the conscience of the people who are against it such as forcing a person to take contraceptives. It would be a kind of law that is essentially a personal choice, it would allow people to use contraceptives if they personally chose too without penalties from the state. And no company should be forced by the state to make contraceptives but if some chose to do so they wouldn’t be prosecuted by the state. If the state tried to force one such as a christian to do something against their conscience, faith, religion, and the divine law, well that is where we draw the line and say no and may have to sacrifice our life for what we believe and merit eternal life. As St Peter said, ‘We must obey God rather than men’.
