承傳自歐洲的前輩，「神格一位論派」與「普救論派」兩個宗派於十八世紀初開始在美國成形。她們起初乃是自由派新教團體，強調一種建基於耶穌及聖經教訓的道德生活。從二十世紀開始，該兩個團體進行了一場進化，離開她們的基督教根基（但未有完全遺棄基督教），成為崇尚個人信仰自由的自由宗教群體。
今天，我們的 UU 教會歡迎任何於生命深處追尋意義、價值、目標、與靈性深度的人，及希望在一個自由的宗教群體裡分享及享受深度生命的人。加入
UU 教會不要求篤信某些教義或信經。
在一九六一年，「美國神格一位論聯會」與「美國普救論教會」合拼，成為我們今日的宗派，「UU
聯會」。聯會總部位於波士頓。我們在北美洲擁有剛超過一千間教會，在世界各地也有我們的教會。
譯自：
The Unitarian and Universalist denominations took shape in America in the late 1700s, drawing upon
their European antecedents. They began as liberal Protestant Christian bodies emphasizing moral and ethical living based on
the teachings of Jesus and Scripture. Beginning in the early 20th century these two bodies underwent an evolution whereby
they moved away from their Christian base (without fully abandoning it) to be free religious communities based on individual
freedom of belief.
Today we welcome into our Unitarian Universalist (UU) congregations all who seek meaning, value,
purpose, and spiritual depth into their lives; and who wish to be part of a liberal religious community where those lives
can be shared and enjoyed. There are no doctrinal or creedal requirements for joining a Unitarian Universalist congregation.
In 1961 the American Unitarian Association and the Universalist Church in America joined to form
our present denomination, the Unitarian Universalist Association. The headquarters of the UUA are in Boston, Massachusetts.
We have just over 1,000 congregations in North America, and a few in various other parts of the world.
