I apologize to pacifist readers. I still maintain, however, that there has been a pre-1800 Christian consensus concerning the other issues, abortion, premarital sex, homosexuality, and social drinking, which Martin mentioned last time. I thought one received moral guidance only from the revealed word of God which in this case is unavailable. Further, some extra-biblical knowledge is required. Scripture is a sufficient source of moral principles, but of course we have the responsibility of applying those principles to present circumstances.
Murder is wrong.
Abortion is murder. Therefore, abortion is wrong. So there are a number of factors entering into the development of a biblical ethic, and each of these can lead to disputes. Nevertheless, a high degree of agreement has been achieved. Consider, for example, the moral issues connected with privacy, free speech, reproductive technology, psychotherapy, democracy, genetic engineering, and the environment.
