Anglican + Roman Catholic + Some Modifications = AA WR

WESTERN RITE ORTHODOXY is the use of the traditional Roman Catholic or Episcopalian Services and Devotionals, as they were done before the changes of the last fifty years. The Antiochian Archdiocese has made some modifications, which reflect proper Orthodox theology. The primary service is the Gregorian Rite Roman Mass, or its Anglican derivative, the 1928 Book of Common Prayer (BCP) Holy Communion Service. – St. Nicholas Antiochian Orthodox Church 1/16/2008
