CUMMING -- Organ music echoed through the room, and voices rang out at The Episcopal Church of the Holy Spirit on Wednesday evening. Many attended the newly renovated church’s short dedication service, which was led by the 10th bishop of the Episcopal Diocese of Atlanta, Right Rev. Robert C. Wright, and Rev. Keith Oglesby, the church’s rector since 2009. Holy Spirit, which sits on Pilgrim Mill Road in Cumming, was expanded with possibility in mind, its mission “building to serve.”
