Mt. Calvary Holy Church was founded in Winston-Salem, North Carolina in 1927 by Bishop Brumfield Johnson when Johnson left the United Holy Church of America along with 200 followers. Johnson next led a revival in Huntington, Long Island, New York, which resulted in a branch of the Mt. Calvary church being founded there as well. In 1929, Johnson and his followers traveled to Boston, where they chartered the Mt. Calvary Holy Church on July 27, 1929. In 1960, the headquarters moved to Boston, following a fire at the headquarters in Buffalo, NY. National Mt. Calvary Holy Church Convocations were held in Boston until an international headquarters was established in Washington, D.C. in 1991.

The Founder of this great church was Bishop Brumfield Johnson, a young, spirit-filled minister, associated with the United Holy Church of America and serving as pastor of the church in Summit, New Jersey. In 1928, Bishop Johnson and Elder Robert Pugsley traveled to Winston-Salem, North Carolina to conduct a revival. Approximately 250 persons were saved at this revival, and many of these new converts desired a church home shepherded by Bishop Johnson. The Winston-Salem church was officially incorporated in 1929.

Bishop Johnson continued the work started in Winston-Salem. During a conference in Summit, New Jersey in 1929, twenty other ministers joined him. Bishop Johnson then traveled with an evangelistic team to Huntington, Long Island, New York where a great revival was held and many were blessed, healed, and saved. This led to the establishment of the Mount Calvary Holy Church in Huntington. 

Bishop Johnson and his fledging group of ministers then traveled to Boston, Massachusetts where they adopted the principles adhered to by the Mount Calvary Holy Church. It was there that the church was chartered on July 27, 1929, with the following persons signing the charter: Bishop Brumfield Johnson, Bishop Lee R. Ligons, Rev. Van T. Pope, Rev. William Bryant, Bro. Augustus A. Granville, Sis. Josephine M. Spencer, Sis. Bessie L. Lipscomb, and Sis. Nancy Hall. In the early 1930s, Mount Calvary began to spread her wings as churches were planted in various cities across the country, including Staten Island, New York, Durham, North Carolina, and Columbus, Ohio. The first Headquarters was established in Baltimore, Maryland, and later relocated to Buffalo, New York in 1942. The Headquarters was then moved to Boston, Massachusetts in 1960 after the Buffalo church was destroyed by fire. The National Convocations were held in Boston until the International Headquarters was established in Washington, DC in 1991.
