With the completion of the Sharon Hall, Sharon Bible College was born in 1955 where several pastors have been trained. Unfortunately the 1950's were a period of unrest within the Indian Pentecostal Church. During the split in Indian Pentecostal Church, the Sharon Hall was often used as a place of mediation, but Pastor Thomas remained neutral. Several independent churches approached Pastor Thomas to help them with building churches and buying burial grounds and to give them a hand in common fellowship. As a result Pastor Thomas decided to remain independent. Although it had a small beginning the church began to grow in leaps and bounds beginning the middle of the 60's He called it a fellowship of churches thus it is called Sharon Fellowship Churches of India, but commonly called as Sharon Church.
