Diocese of Vellore of the Church of South India
The Diocese of Vellore is one among the 24 dioceses of Church of South India. The motto chosen for the diocese was "In the Cross of Christ I Glory" (based on Galatians chapter 6 verse 14). Its emblem includes a banyan tree - the tree under which the Scudder brothers prayed before they decided to begin their work in the area of Vellore. History
The diocese was created by bifurcating the western half of the Diocese of Madras and was officially formed on 26 January 1976.

St. John's Church, Vellore Fort

St. John's Church, Vellore located inside the Vellore Fort was raised in 1846 by the Government of Madras for the officers and men of the East India Company military station. The church is named after St. John the Evangelist. However, the church was never officially consecrated and hence not officially named St. John’s Church. St. John's Church is the oldest standing church in the Vellore Diocese.
