Everyone has different values. Do you want to live in a society that tells people to do what's right based on what each individual values or doesn't value?
In a democracy/republic we as a group create laws that are voted on. These are our civic laws that govern us as a group. So it's not an individual but what a majority of individuals value.
In a dictatorship, it'd be an individual, which may ok by me if I gets to be the dictator. :yes:
There is a system to determine the values we govern ourselves by. The Bible has no authority in this system anyway. It's the reality of what we have now. So how do you like it?
Morals are my personal sense of right and wrong. They may at times conflict with civic laws. Ok, well the civic laws are enforced by the group. There's no "earthly" enforcement of biblical laws. Your biblical morality is between you and God anyway. You are free to accept this morality as long as they don't conflict with civic laws at least in the US. I'm thinking Mormons and polygamy for example.
So you don't need to worry so much about my individual morality since we have enforcement of civic laws.
You and I may disagree on some moral issue, however the group provides enforcement not according to our individual morality but on civic laws.
Some civic law you don't like, you are free to try and change it. Like the homosexual community are trying to change our civic laws regarding marriage. Maybe you don't like it but as part of the group you have to respect the civic laws.
