Medak was formerly popular as Siddapur Medak, the prefix however, lost its importance in the popular usage. It is located in Telangana State. Sangareddy is the district headquarters of Medak.
The district was situated between 77° 28' and 79° 10'E, of the eastern longitudes and 17° 23' and 18° 19'N, of northern latitudes. The district is bounded by Nizamabad District to the north, Hyderabad District to the east and south, Warangal and Nalgonda Districts to the east, and Karnataka state to the west.
The district has population 30,33,288 as per the 2011 census which accounts for 8.62% of the total population of the State with 13.6% decadal growth.
The church was built under the stewardship of the Methodist Christian, the Reverend Charles Walker Posnett, who was driven by the motto My best for my Lord. Charles Posnett had arrived in Secunderabad in 1895, and after first ministering among British soldiers at Trimullghery, had launched into the villages and had reached Medak village in 1896. In those days there was no railway to Medak (the journey of 60 miles (97 km) from Hyderabad had to be done on horseback - and Posnett could do it in a day) and in the whole Medak area there were hardly two hundred Christians, who were using a small tiled house as their place of worship.
As the number of Christians increased, Charles Posnett raised a moderate structure in the Mission Compound in the shape of a church, but thought it unworthy, and early in 1914 laid the foundations of the present cathedral church, on 1,000 acres (4.0 km2) of land in Ghusnabad area. When the people of Medak district were suffering from famine between 1919 and 1921, Charles Posnett helped them by employing them in the construction of the church instead of running a free kitchen. Construction went on for 10 years. Charles Posnett consecrated the church in 1924, thanking God for mitigating the sufferings of the people.
