Is this some new religion?
Not at all. Unitarian Universalism has its roots in -- no surprise -- two historic religions: Unitarianism and Universalism. Both were based in Europe and are hundreds of years old. In 1961, the two religions merged and the resulting faith has reflected goals of spiritual and intellectual honesty, and an urge to make the world a better place.
You'll probably recognize the names of some recent Unitarian Universalists, like Robert Fulghum, Christopher Reeve and Kurt Vonnegut, as well as those of historical Unitarians and Universalists, such as Presidents John and John Quincy Adams, Charles Dickens, Louisa May Alcott, e.e. cummings, and Frank Lloyd Wright.
