Administration of the Armenian church in America has been divided since 1933, when a split developed over the status of the church in Soviet Armenia. The Armenian Apostolic Church, fearing communist infiltration, chose to ally itself with the Catholicate of Cilicia in Lebanon rather than with the Patriarchate in Armenia. The Armenian Church of America, the church's original U.S. diocese, founded in 1892, remained loyal to the Patriarchate in Armenia.
A "unity commission" is working to bring together the two jurisdictions, both of which are based in New York. There are an estimated 1 million Armenian Christians in the United States.
