The Church of Christ among the Garo people is one and a half century old. Way back in 1863, on 8th February, the first two Garo converts Omed Watre Momin and his nephew Ramke Watre Momin were baptized in Gauhati by Dr. Miles Bronson, an American Baptist Missionary of the Nowgong Baptist Station. Immediately after their baptism, both of them wanted missionaries to be sent to their people so that they too might get to hear the good news. When their request went unheeded, they decided that they themselves must go. The duo returned to their homeland in March 1864 and began evangelizing their own countrymen. After three years of painstaking efforts, Omed was able to win thirty-seven of his tribesmen for Christ. Dr. Miles Bronson came to Rajasimla village and baptized the new believers and thus the first Garo Church was established at Rajasimla village in April 14, 1867, with Omed as the Pastor.
The following year, another 23 converts were won by Ramke and baptized by Bronson in Damra in June 28, 1868 and thus another indigenous church was established there which was later shifted to Nishangram. Thus, the first two converts became the harbinger of the gospel to the Garos. The Garos were in the forefront of pioneering mission work in places like Arunachal, Bhutan, Impur area of Nagaland and Kangpokpi area of Manipur. One of the stalwarts who spearheaded the mission work among the Garo Christian was Rev. Thangkan K. Sangma who even participated in the World Mission Conference held at Edinburgh, Scotland, in 1910.
