Over 125 years old, The Cathedral Church of Saint John the Divine is the largest cathedral in the world. It is the “mother church” of the Episcopal Diocese of New York and the seat of its Bishop. The church is chartered as a house of prayer for all people and as a unifying center of intellectual light and leadership.
While Cathedrals traditionally do not have their own congregations, St. John the Divine is home to the Congregation of Saint Saviour, which operates independently from the Cathedral. The congregation has approximately 400 members. Information about services and times can be found below. Furthermore, all those who would like to attend worship services and anyone seeking a place for prayer or meditation will be welcomed without charge. For sightseeing, visit the admissions page to learn more.
Like the great Medieval cathedrals and churches of the world, St. John the Divine is unfinished and will continue to be constructed over many centuries. Currently, funding is mostly directed towards maintaining the architectural integrity of the Cathedral and prioritizing serving the community through programming and social initiatives.
Some of St. John’s community initiatives include the soup kitchen (which serves roughly 25,000 meals annually), the distinguished Cathedral School (which prepares young students to be future leaders), Adults and Children in Trust (a renowned preschool, afterschool and summer program), and the outstanding Textile Conservation Lab (which preserves world treasures). The Cathedral also organizes several yearly concerts, exhibitions, performances and civic gatherings to allow for conversation, celebration, reflection and remembrance—such is the joyfully busy life of this beloved and venerated Cathedral.

Photography Exhibition: Into the Streets! New York City’s Pride March 1975 – 1976

TICKETS/REGISTER LINK
“Out of the Closets! Into the Streets!: New York City’s Pride March, 1975-1976” opens to the public on May 8. Featuring 20 photographs by internationally-recognized multi-media artist @franciscoalvaradojuarez, this exhibition provides a window into the world of New York City’s early Pride marches, known at the time as the “Christopher Street Liberation Day March.” The marches served as a vital call for increased queer visibility at a time when New York still enforced so-called “sodomy laws” that targeted the LGBTQ+ community. Alvarado Juárez’s photos of the 1975 and 1976 marches showcase the racial and ethnic diversity of the early Pride parades and reveal the nuanced bonds of kinship formed among marchers from disparate backgrounds. Continuing the Hispanic Society’s commitment to exhibiting work by artists active in the local community, “Out of the Closets! Into the Streets!” constitutes the second installment of the annual series “Arte en el Alto Manhattan” which highlights artists residing in Upper Manhattan. Stay tuned for updates on special events and programming related to this exhibition.
