I think the main body of debate your leaning toward is, is contraception right or wrong? In the NT Paul said that there is nothing evil within itself only the misuse of it, so there's nothing really evil about using contraception, just the method would be questionable. Paul said all things are lawful unto me, what he was saying was to silience the religious critics asking him many questions about many subjects. Paul basically said, where it doesn not conflict with scripture or you find no express directive from God then use your godly common sense and choice as to what belief you want to hold. There's no directive about preventing life, only taking it, as you and I would both agree, abortion is murder but an unfertilized egg is no life at all requiring both the male and the female to make it so. I must admit, I might disagree to some extent with the 'pill' or the morning after pill bu condoms and what not, I can't see an issue...
