In 1953, Gurukul received a new life with a wider participation of the Lutheran Churches and so was named as Gurukul Lutheran Theological College and Research Institute. The college was then affiliated to the Senate of Serampore College for graduate and postgraduate Studies. Dr. Sigfrid Estborn became its Principal. Then Gurukul merged with the United Theological College, Bangalore and Serampore College, West Bengal in 1971. From then on, Gurukul became a centre for continuing and extension education for the churches in India under the stewardship of Dr. K. Rajaratnam.
