Introduction
Abortion has recently become a hot topic again in American politics. With President Trump's appointments of conservative judges to the Supreme Court and the States' legislators proposing and passing more restrictions on abortions, it is very possible that we will see the decision that legalized abortion (Roe v. Wade) challenged, if not overturned.
I was in a discussion with a fellow pro-life advocate this week, and he took issue with my use of science to make the case for the humanity of the unborn. His position was that we did not need to use science but only use the Bible to make the case. So, I was in a position of needing to defend my defense.
Sources of Truth
I want to start out by affirming my pro-life brother in his belief that the Bible is indeed sufficient to make the case, but it is sufficient to make the case to Christians- those who recognize the Bible as an authoritative (and inerrant) source of truth. But not everyone accepts the Bible as an authoritative source of truth. Not everyone in America (and especially not in American government) is a Christian, and even if people are Christians, there is no guarantee they hold the Bible to be inerrant and the final authority in their lives. For people in these two categories, making appeals to the Bible to argue for anything is not going to get very far. If we want to see a non-Christian or a more "liberal" Christian agree with us against abortion (or any other matter of truth), we need to argue to our conclusion using a source of truth that they also recognize.
