St. Mary's came into existence on January 6, 1945, under the direction of
Fr. Edward Wahl of the Oratory. At that time, there were only five adult Black
Catholics in Rock Hill. Since community services were limited, youth groups
were encouraged to meet at the Oratory, for recreation and prayer. As the
numbers increased, the need for a church became apparent. By 1946, with help
from many benefactors and Bishop Walsh, the Parish purchased the present site
on Crawford Road and began arrangements for construction.The first Mass was
celebrated on July 4, 1946.
In 1949, A Women's Club became active as an affiliate of the Diocesan Council. The club was later renamed St. Mary's Rosary and Confraternity Society, and to this day, still exists. At that time, the men also formed the Holy Name Society. Membership increased to include a Gospel Choir which today is recognized both locally and regionally. Parish families were priveleged to share the combined contributions of exceptional Priests and Religious Sisters, who, in addition to regular responsibilities, supported community services, such as the Dorothy Day Soup Kitchen in the church annex; later transferred to Bannon Hall, a Parish on-site facility. The primary purpose of this service is to provide a meal during the day, to anyone in need. The Soup Kitchen is still in operation, with volunteers ensuring that the obligation is fulfilled. Future plans for building improvements, though somewhat restricted, are periodically updated as needs arise.
