1849
A congregation begins
Rev. James A. Gloucester, who had been enslaved, organized Siloam Presbyterian Church in Brooklyn. The congregation became a place of worship and resistance to slavery.
Our Story
Since 1849, Siloam has been a place of refuge, courage, and community. Our story is woven into the story of Brooklyn—and the ongoing work of justice.
Over 175 years of faith & service

From the Underground Railroad to the movement for equal education, our congregation has understood that faith and justice belong together.
1849
Rev. James A. Gloucester, who had been enslaved, organized Siloam Presbyterian Church in Brooklyn. The congregation became a place of worship and resistance to slavery.
19th century
Siloam participated in the Underground Railroad, providing food, clothing, and refuge to people escaping slavery. Its Literary Union fought segregation and advocated for Black educators.
1944
Under Rev. George Shippen Stark, Siloam moved from Lafayette Avenue to its current home at 260 Jefferson Avenue, closer to Brooklyn’s growing African American community.
1948–1988
Rev. Milton A. Galamison led the church for forty years and became a nationally recognized voice in the struggle for educational equality and the desegregation of New York City public schools.
Today
Siloam carries its legacy forward through worship, a community food pantry, health ministry, youth partnerships, and the arts—serving God by serving all people.
