Brooklyn's 863 Parishes by Neighbourhood: Sunday Morning in the Most Densely Churched Borough

Brooklyn holds 863 parishes inside its borders, the highest parish count of any New York City borough and the highest parish-per-square-mile count of any American jurisdiction of comparable size. Brooklyn's 70 square miles hold roughly 12 parishes per square mile, a density that outpaces Manhattan (not the per-capita rate but the per-area rate), Chicago, and every other American metro. The neighbourhoods that hold the densest parish counts are almost all twentieth-century immigrant-era neighbourhoods: East Flatbush, Crown Heights, Bedford-Stuyvesant, Sunset Park, Bushwick, Bensonhurst.

Bedford-Stuyvesant and Crown Heights: the Black Baptist and AME grid

Bedford-Stuyvesant and Crown Heights hold the highest parish density in the borough, most of it Baptist, AME, AME Zion, Church of God in Christ, and Pentecostal. The neighbourhoods absorbed much of the Great Migration into Brooklyn between 1915 and 1970, and the resulting church grid is tight: a parish every block or two on Fulton Street, Nostrand, Bedford, and Eastern Parkway. Mount Sinai Baptist Church in the Bedford area is representative of the 1940s-founded congregation size (200 to 400 members). The mega-church scale that Houston and Atlanta Black Baptist congregations reached never took hold in Brooklyn, where real-estate constraints kept Baptist parishes modest.

Sunset Park: Chinese, Mexican, and Norwegian layers stacked on the same streets

Sunset Park holds three distinct parish grids on top of each other. The Norwegian Lutheran and Reformed parishes from the 1890–1940 Brooklyn Norwegian enclave (Lapskaus Boulevard) sit on Fifth Avenue and Fourth. The Mexican Catholic parishes planted from 1990 forward, many of them with Our Lady of Guadalupe devotions, sit on Fifth and Sunset Park itself. The Fujianese and Cantonese evangelical congregations that filled Eighth Avenue after 2000 added a third layer. Three of the four largest Norwegian Seamen's Church parishes in the United States were in Sunset Park before the 1970s; two remain.

Bensonhurst and Bay Ridge: the Italian Catholic anchor

Bensonhurst and Bay Ridge hold the largest cluster of Italian-origin Catholic parishes in the five boroughs. The Diocese of Brooklyn maintains St. Athanasius, St. Dominic, St. Finbar, and St. Philip Neri parishes in Bensonhurst alone; Bay Ridge holds St. Anselm and Our Lady of Angels. Bensonhurst's parish grid dates to the 1900–1930 Italian migration that displaced an earlier Norwegian population west to Sunset Park. The 2000s Chinese and Hispanic in-migration has added Spanish-language Mass times at several of the Italian-founded parishes.

Flatbush and East Flatbush: Caribbean Protestant and Catholic

Flatbush and East Flatbush hold one of the densest Caribbean-origin parish grids in the United States. Haitian Catholic parishes, Jamaican and Trinidadian Pentecostal parishes, Seventh Day Adventist congregations (the Caribbean Protestant identity overlaps heavily with Adventism), and Baptist parishes founded by Caribbean migrants sit on nearly every ten blocks. Flatbush alone has more than 60 parishes in a 3.1-square-mile area. The Bedford-Stuyvesant / Crown Heights / Flatbush triangle holds roughly 340 of Brooklyn's 863 parishes inside a 9-square-mile footprint.

Greenpoint and Williamsburg: Polish Catholic and Hasidic boundary parishes

Greenpoint holds what is arguably the largest Polish-language Catholic parish population outside Poland. The six Polish national parishes in Greenpoint (and adjoining Williamsburg, north of the Williamsburg Bridge) serve a community that has recovered from its 1990s post-communist peak and that still offers Polish-language Sunday Mass at six places within a one-mile radius. On the Williamsburg side, the parishes border the large Satmar Hasidic community that sits south of the Williamsburg Bridge — a neighbourhood with essentially no Christian parishes but more than 100 Jewish houses of worship.

Park Slope and Brooklyn Heights: the historic mainline Protestant grid

Park Slope, Brooklyn Heights, and Boerum Hill hold the older Episcopal, Presbyterian, and Congregational parishes founded between 1820 and 1880 for the Brooklyn professional class. Bedford Central Presbyterian Church, Plymouth Church (Abolitionist anchor where Henry Ward Beecher preached for 40 years), Grace Church, and the Cathedral Basilica of St. James (the original Roman Catholic cathedral of Brooklyn) all sit in the Heights / Fort Greene / Downtown Brooklyn cluster. The old New Utrecht Reformed Church, now in Bensonhurst, predates all of them — its 1700 congregation is the oldest continuously-operating Dutch Reformed church in the United States outside Albany. The present New Utrecht Reformed Church building is on its 1828 foundation.

Saint Laurence and the John Wesley Methodist node

St. Laurence Catholic Church and John Wesley United Methodist Church are representative of the mid-century Brooklyn parish scale: 150 to 400 weekly attendees, a single pastor, a building that predates the Second World War, and a Sunday schedule of two or three services.
