Worship at St. Gregory the Great centers around the celebration of Holy Eucharist. Relying on the flexibility and liturgical richness of The Book of Common Prayer, the congregation of St. Gregory practices both traditional and innovative modes of worship. The language of the service is inclusive, as is congregational participation in worship roles: acolytes, lay readers, Eucharistic ministers, ushers, altar guild members, flower guild members, and musicians. All confirmed members of the church, regardless of age, race, gender, or sexual orientation are encouraged to assist in the experience of worship. Most importantly, all of the congregation are invited to the Eucharistic table to share the bread and wine.
