Re: churches
The Orthodox Church in America (OCA) hasn’t been affiliated with the Russian Orthodox Church in over a century, and today consists predominantly of converts (of western and central European ancestry) with services almost exclusively in English.
ROCOR is an extension of the Russian Orthodox Church, but accounts for a small number of total Eastern Orthodox Christians in the United States.
Most Eastern Orthodox Christians in the United States belong to either the OCA, Greek, or Antiochian dioceses/metropolises.
