History of this community

Q: So UUGSB is starting anew, after a 60+ year history?

A: Yes! Here’s our origin story, and why we’re making a fresh start now.

1957: A group of friends, many of them scientists at Brookhaven National Lab, started a weekly discussion group that met in their homes. Advertising attracted more members. They began using the YMCA in Patchogue. Seeing a need for some kind of education for their children, the group decided that Unitarianism fit well with their humanist bent, so they became the Unitarian Fellowship of Brookhaven.

1961-2010: After buying the property at 51 Browns Lane in Bellport Village, the group was known as the UU Fellowship of Bellport. The late 80s saw some decline in membership as the founding members and their children got older. The first of several ministers was hired.

2010-2012: The congregation dreamed of growing larger, and decided to move. As the search for a new location continued, the group gathered in temporary locations.

2012: We purchased the former Sayville public library building and adopted the name “UU Congregation of the Great South Bay.”

2012-2018: Even as we settled into our new home, we discovered additional work that had to be done to the property. Meanwhile, the period of dislocation and relocation took a toll on our membership. Longtime members moved away from Long Island. Elder members cut back their participation from necessity. Others decided to join nearby UU congregations.

The core group of remaining members has resolved to make a fresh start, beginning with a spruce-up of our building & grounds, a revamped website and a publicity campaign to introduce ourselves to the wider community.

2019-?: We’re forward-thinking and have high hopes for the next stage of this journey. We are now, as in the beginning, a lay-led bunch, mostly with a humanist bent, who seek meaningful connection and a better world.

“I love to walk in the forest, and everywhere in the forest there is death…Yet there is also new life emerging from the midst… Fallen trees become rich nurse logs… A great-grandchild shares the stage with a dying dad.” — Jaco Ten Hove, in “After a Dying Dad” from Winter 2016 UU World.

History of the UU denomination

from “Unitarian Universalism: A Short History” by James Ishmael Ford

“…Personally, at the beginning, I blame the Enlightenment. [When people] noticed they could take the same skills that were revealing the secrets of the natural world to the workings of the mind and heart and even to their religions, something wondrous birthed into the world. It would variously be called rational religion and liberal religion.

“Throughout the eighteenth century, some broad principles were worked out through a critical engagement with traditional Christian doctrines and texts. One scholar tagged these as freedom, tolerance, and reason. While these currents would find homes in nearly all religions, by the first decades of the nineteenth century in North America two denominations emerged that were particularly devoted to this approach, the Universalist Church of America and the American Unitarian Association. Despite their deep similarities, for various reasons it would take more than a hundred years for these two communities to consolidate. Finally in 1961, they did, forming the Unitarian Universalist Association.
