There certainly are (and even for those of us not counting themselves as Christians, 'do unto others...' would seem to be a pretty universal starting point!)
What is considered moral for some (eg women's rights) is not necessarily moral for others. There are still many places that a woman can not vote or must obey her husband! That's just one of many things.
This is where...
'do unto others...'
... utterly fails. And why there are religious wars at all!
