Our services are sung in English and we have service booklets for those who would like to join in singing the prayers, as well as those who simply wish to follow along. We typically stand to worship, but we do have chairs and you are welcome to sit as needed. You will notice considerable diversity in the way participants engage in various gestures of piety during our services: making the sign of the cross, lighting candles, kissing icons and crosses, singing, standing, sitting, bowing, prostrating - each person participates in the service personally, even as we all are worshiping God together.
Each week, our liturgical cycle begins with Great Vespers on Saturday evening. The principal service of the week is the Divine Liturgy on Sunday morning, which is preceded by the Priest's service of Proskomede and Third Hour Prayers. Other services, including the Great Feasts of the Church, special Lenten services, and the services of Holy Week are served as announced.
