We live in a culture that doesn’t understand the word “truth.” For example, as Catholics, we believe that abortion is wrong. However, if you believe it is wrong and you “personally wouldn’t have one, but it’s not my place to tell someone else that they can’t,” then you are confused. If it is wrong, it is wrong for everyone, whether or not they subscribe to the same faith or worldview is irrelevant. If it is true, then it is ALWAYS true for EVERYONE.
We’re all sinners. That doesn’t make it ok, but it is a fact. We all have to be diligently working to eradicate sin from our lives. Not only that, but we have a responsibility to help others do so as well. Moral relativism means that morality (the truth of what is right and wrong) is relative to each culture. That means, what is true for me may not be for you… which doesn’t make sense. To use the issue of abortion again, it is always wrong. Just because YOU might disagree doesn’t change the truth. You simply disagree with the truth.
We have a responsibility to correct sinfulness—our own and that of others. We have a responsibility to share the truth… and to live by it.
