I also think that Christian scripture teaches us that we should be socially responsible. To me, this means being generous and caring to people who are in need. It may take the form of volunteering or something as simple as giving someone a shoulder to cry on.
I suppose people who actually read Christian scripture may interpret things different ways so it really means something different to everyone.
It is a bit unrealistic, but the scriptures give us the (sometimes false) security that the good will end up good and the bad will end up bad; that the bad people will be punished, and that good people will be rewarded.
It is comforting to think that this is possible, but, realistically speaking, one would perhaps be less angry, less frustrated, and less spiteful if one simply looks at the reality of it all: Bad things CAN and DO happen to good people, and good things happen to bad people. Life is not fair, and there is no certainty in it.
However, keeping faith in the scriptures does seem to help some people who need that assurance.
I think that the most attractive thing about Christian scripture as it relates to society is its emphasis on treating all people fairly and caring for all people. This is something that we do not always do as well we might in our society.
I am thinking, for example, of Jesus's idea that whenever people do something to the "least of his brothers" they are doing it to him as well. This would imply that our society should be compassionate to all people and should treat them as we would like to be treated ourselves. I believe that this is a very profoundly ethical stance and I think that we would be better off if we adhered to it more closely.
I think in the Christian scriptures there are many teachings which can reduce the element of extremism from the world but only if it is acted upon. For example there is a teaching in the new testament that if someone slaps you on right side of your face then turn the left side of your face to him or her to be slapped again.
If this teaching is acted upon then the result is peace in the world.
