Saint John's Church is a congregation of Christians worshiping in the  Diocese of Maryland of the Episcopal Church in the United States of America and within the Anglican Communion. The congregation maintains a full regimen of daily worship in accordance with The Book of Common Prayer of the Episcopal Church. The purpose of Saint John's Church is the worship of Almighty God, the disciplined spiritual formation of its members, and evangelical witness to a new life in Christ Jesus through service to others. This high calling is attempted through the Holy Eucharist as a covenant of renewal and reconciliation; in the Daily Office of the Church as a sacrifice of praise in prayer; in the offering of our personal time, fortunes, and abilities for God's service in the community; and by engaging in serious study of our rich Christian heritage. To further these ends and as a witness to all, the congregation supports a liturgical musical program of highest quality to preserve to our use in our day and for generations to come the spiritual treasury and deep well of the Anglican musical heritage. Our mission is to take up our part in restoring all people to unity with God and each other in Christ.
