how can we governmentaly make decisions based on any one religion's principles and say that it is a seperate government and state or say that is a land of religious freedom if you could get penalized based on someone else's religous principles.
Is there a more foundational role to the government?

we can feed the poor and provide shelter for the needy and help with the healing of the sick through our vote as well, but I am not sure if these are things that the government should be in. I can't see why not.

I suppose if you have a Christian majority in a democracy they have the right to impose their principles on people who do not want them. It just feels a little more like controlling actions instead of changing hearts.

Is the government about rewarding and punishing the outward actions? But what actions?
