Holy Eucharist, Rite II according to the Book of Common Prayer is celebrated each week. The three Sunday services differ in style. St. Peter's Chapel located on Solomons Island and Middleham Chapel located on H. G. Trueman Road, Lusby are the more traditional services. The worship service in the Great Hall is somewhat informal with a mixture of traditional and contemporary music. Volunteers are involved in each service as greeters, lay chalicists, readers, and coffee hour hosts. Each Wednesday morning a service of Holy Eucharist with the laying on of hands is held at St. Peter's Chapel. Middleham Chapel is home to a Tracker Action Nyack pipe organ, and St. Peter's has a two manual Wickes pipe organ.
Choir — The choir is open to all ages and voices. They practice once a week and singing in rotation at the three Sunday services. Everyone is welcome and no audition is necessary.
Acolytes — Youths age 9 or older may volunteer to be an acolyte. Acolytes serve or assist the priest conducting the service. They are trained to serve at both chapels and the Great Hall for Sunday services and other special services throughout the year.
Altar Guild — Anyone may be a member of the altar guild. Members prepare the worship spaces for all services by arranging flowers, cleaning the materials for the Eucharist, tidying up the chapels, filling the liquid candles and listing hymns.
Lay Chalicists — Lay chalicists assist the rector during the Sunday services and special services throughout the year. Responsibilities include serving the chalice during the Eucharist, reading the Epistle, leading the Psalm and conducting the prayers of the people. They also lead Morning Prayer in the chapels when requested by the clergy. Training is provided.
Lay Readers — A lay reader is the person who is assigned to read the first lesson on Sunday during the Eucharist at one of the three worship services.
