Earlier quoted context omitted.
It's quite simple, really: «Love one another». This is THE thing that Jesus said we should do, and it takes precedence over anything else. For example, sure, some minor book in the Bible might say that's it's kinda bad to be gay, but hating other people that disrespect a minor recommendation is contrary to the most important commandment.
I struggle to grasp this concept when USA, a very Christian county, doesn't seem to have policies that follow loving each other. Income inequality is rising and there is plenty of argument on who can marry whom, etc. It's very strange that a religion founded on love has not been in some military conflict more than a decade or two.
There are many christian churches and religious groups that function more as social organizations than religious ones. I wish they organized around something besides religion as it would make it less confusing but I don't really have a problem with this. I just don't expect the same views and behaviors from them as I would from myself or from people who take their religious beliefs more seriously.
Most political leaders in the United States these days make only the most feeble attempts to convince constituents of their "faith". So it should not surprise you that this country is not a beacon of Christian values in policy or actions.
