Brief History: All Nations Theological Seminary has taken its shape in a gradual process. It was started as Good Shepherd Bible Institute by Rev. Dr. David W. Cho and his wife Mrs. Grace Cho in 2001. It was initially run in rented facilities at Panjabi Para, Siliguri. The purpose of this Institute was to train the local Christian leaders in the word of God and to offer them the Certificate of Theology for the work of God in the Himalayan regions and beyond. In two years thirty students were trained for the mission of God.

The passion of developing many more national and international mission-oriented Christian leaders with appropriate biblical and theological knowledge for the mission of God in the Himalayan and Trans-Himalayan regions continued to grow in the heart of Rev. Cho. This very passion and his love for God and for the Himalayan people led him to look for a suitable land to build a permanent place for the Theological Seminary. In 2001, Rev Cho with the help of Pastor Purna Bahadur Chettri and other local leaders formed the trust, “Gospel Crossing Asia” and registered with the Government of West Bengal, India. In the same year, about four acres of land for the Theological Seminary was purchased at Bainya Khari, Matigara and registered in the name of the Trust. The foundation of the new Seminary was laid on 12th September, 2001 and by the middle of 2003, the new campus along with the basic administrative facilities for operating residential theological training for about eighty students had been set up.

Since June 2003, Good Shepherd Bible Institute was shifted from a rented building to its own new campus and was renamed, “All Nations Theological Seminary.” From that very moment, the Seminary started to enrol students for the Bachelor of Theology course along with the course Certificate of Theology. From 2006, the Seminary stopped the course Certificate of Theology and started the higher course, Master of Divinity. Since then, the Seminary has been constantly striving for academic excellence, ministerial skills development, and character formation of every single student. In 2013, the Seminary received its academic recognition from Asia Theological Association for both Bachelor of Theology and Master of Divinity programmes.

The blessing of the Almighty God is very much evident in the short history of All Nations Theological Seminary. It was started in a rented building with handful of people. Today it has a beautiful campus in four acres of land with concrete administrative buildings, sufficient class rooms, spacious library with about 12000 title books, chapel building with 300 seating capacity, separate hostel buildings for boys and girls with 60 beds capacity in each hostel, beautiful kitchen and dining hall, staff quarters and guest rooms. Over the few years, about two hundred fifty young men and women from different states of India and from neighbouring countries have been trained for the mission of God. Most graduates are presently rendering effective service for churches and societies, especially in the Himalayan regions and its surrounding places. They are passionate to save lost souls, to serve people, and to sacrifice themselves for the cost of the cross. All these evidences clearly prove the significant existence of All Nations Theological Seminary in Siliguri, at the foothills of Himalayas.
