Founded in 1913, St. Constantine Church was the first Greek Orthodox Church on Long Island. The church became Brooklyn’s Cathedral in June 1966.

The Cathedral is a center of the Greek Orthodox Faith and Hellenism in Brooklyn, and is visited by many dignitaries from Greece, Cyprus and the United States.

Christians of the Eastern Churches call themselves Orthodox. This fifth century description means “true praise.” In other words, to bless, praise, and glorify God the Father, Son, and Holy Spirit is the fundamental purpose of the Orthodox Church.

While the Orthodox Church contains individuals from numerous ethnic and cultural backgrounds,
a large percentage of her membership is composed of persons who were born in America. In recognition of this, Orthodoxy has been formally acknowledged as one of the Four Major Faiths in the United States.

Following the practice of the Early Church, Orthodoxy treasures the various cultures of its people, but it is not bound to any particular culture or people. The Orthodox Church welcomes all.

There are about five million Orthodox Christians in the United States. The largest Orthodox Christian community is the Greek Orthodox Archdiocese of America, which has about 500 parishes throughout the United States.
