St. Mary Armenian Church is one of only five Armenian churches in New Jersey and draws members from several nearby counties. Led by Father Souin, who has been pastor for nine years, the church's motto is "The Little Church that Shares and Cares at Prayer." The Divine Liturgy is conducted in English and Armenian, with hymns sung in Armenian by a choir.
St. Mary parishioners have many opportunities to take part in Armenian cultural activities. In addition to a regular Sunday school, the church runs the Aratian Armenian School, which provides three levels of instruction (Pre-K/K, beginner, and intermediate) in Armenian language, history, dance and music. The church also has youth groups that emphasize Armenian heritage. Choreg (traditional Armenian bread), fresh from St. Mary's kitchen, is sold on Sundays, and Armenian food is a part of many church activities.
