You might THINK the Unitarian church "stands for the principles of Jesus."  Maybe they do.  If so, that's an accident; a mere coincidence.  There are people with backgrounds in Christianity, Buddhism, Hinduism, Judaism, animism, etc. who call themselves Unitarians.  Unitarianism has no creed, no specific concept of God(s).  In fact, they are very proud to have no creed, because they think creeds cause divisiveness between people who believe or don't believe in them.  They focus mainly on "social justice", helping our fellow man (and woman, and animal), and all manner of feel-good things which are not inherently related to any particular theology.
