"St. Mary's Orthodox Church is an intriguing and complex religious institution. The community is characterized by an acceptance of diversity and eclecticism, an emphasis on the notion of the congregation as a family, and a deep commitment to the act of devotion.

Its religious tradition is of the Antiochian strand of Eastern Orthodoxy, but it is a pan-Orthodox church with an English language liturgy and a congregation comprised of Syrians, Lebanese, Greeks, Russians, Eritreans, Ethiopians, Ukrainians, Romanians, Bulgarians, Koreans, Chinese, Latinos, and American-born converts."
