[link|http://www.biblegateway.com/passage/?search=john%203:16;&version=9;|John 3:16]:

I think that's the usual minimum.

But since there are [link|http://www.paintcreek.org/resources/sermons/moral_atheist.shtml|atheists who are Unitarian Universalists], there are probably Christians out there who reject that passage.
