The Cathedral parish is composed of several hundred souls of various ethnic heritages, third generation Romanian-Americans, and a growing number of those newly-arrived from Romania. Services are celebrated in both the Romanian and English languages.

In faith and practice, the Orthodox Christian Church is the organic continuation of the One, Holy, Catholic and Apostolic, True Church established by Jesus Christ. She maintains, without addition or subtraction, the faith, "once and for all delivered to the saints", and taught by the Apostles since the day of Pentecost, two millennia ago. She is the Biblical Church revealed in the pages of the New Testament.
