"Liturgical services are not one of the 'aspects' of the Church; they express its very essence, are its breath, its heartbeat, its constant self-revelation."
--Fr. Alexander Schmemann
"During the dark ages of Orthodox Theology, our Church survived because of the richness of her liturgical life. If you understand our various liturgical services, you will understand the whole theology of the Orthodox Church. While others talk about liturgical poverty and liturgical renewal, as Orthodox, we must concentrate our efforts on liturgical understanding."
--An Orthodox Hierarch
The communal worship of the parishes of our Archdiocese depends on the labors of our bishops and clergy, and of the dedicated work of multiple departments and organizations.
