Under the leadership of the Reverend Ray Pradat (1970-73), there was a substantial growth in membership. On January 29, 1977, at the 150th Annual Council in Oxford, Mississippi, Calvary Episcopal Church became a parish with the Reverend James Pulliam as its first rector. (An interesting side note in the history of Calvary Cleveland: Bishop Duncan Gray served the church during its early organizational days (1925-26), Bishop Duncan Gray, Jr. served as Vicar 1953-57, and Bishop Duncan M. Gray, III spent some of his formative years in Cleveland while his father was at Calvary). In order to accommodate the increase in numbers, a duplex located next door to the rectory was purchased and converted into a Sunday school and office complex.
Some recent improvements to other buildings include the addition of three large stained glass windows (memorials) in the church proper, extensive landscaping, a fountain outside the church, and renovations to the interior of the church itself. As part of the interior renovation, a new sacristy and vesting room were added on the west side and a covered walkway connecting the church and parish hall was added on the east side.
Recently the Episcopal Church Women (ECW) and Men’s Group collaborated to update the Rectors’ and Church office. Major renovations to the Rayner House were carried out in 2010.
