You're right about my expectation of consistency for there to be social benefit. I just have an expectation of consistency from those claiming to have a monopoly on fundamental truth in the universe. My expectation has nothing to do with social good in that case.
About The Greatest Commandment and the Golden Rule? As directly quoted from Jesus? If so, this definition of "Christian" is far too encompassing to be useful in this discussion.

What I'm quoting is even less controversial than the Nicene Creed, which is unanimous among major Christian denominations. They can't even agree on what day of the week is the sabbath and what day of the year is Easter, but they all agree on The Nicene Creed. And they absolutely agree on The Greatest Commandment.
There is not as much controversy about the basics as you seem to think there is.
