The Graduate School of Philosophy and Religion was founded in June 1993.  Initially, it offered two programs: an MA in philosophy and an MA in religious studies. It established a Ph.D. program in philosophy in October 1997 and a Ph.D. program in religious studies in June 2001.  All four programs are recognized by the Commission on Higher Education.

Since 1996, the Graduate School of Philosophy and Religion has dedicated itself to preparing its graduates for service to society in Thailand and around the world.
The Graduate School shares the vision and mission of Assumption University, which is to become an international community of scholars, enlivened by Christian inspiration, engaged in the pursuit of truth and knowledge, and serving society.

The Vision
The Graduate School of Philosophy and Religion strives to assist its graduates in the development of high intellectual and moral values, so they can serve as a beacon of light in their own communities.

The Mission

1. To create persons of integrity committed to lifelong learning that will continue to guide the graduate in their personal growth.
2. To achieve this goal, an interdisciplinary approach is used in all programs. There is a special attempt to harmonize the intellectual and the spiritual in consonance with the saying of Einstein: "Science without religion is lame, but religion without science is blind." The school also follows the path of harmony between Eastern and Western thought in philosophy, religion and science.
3. To enhance this harmony, the school promotes pluralistic thinking. The school is itself a community of professors and students who come from diverse backgrounds of religious belief, culture, and nationality.

Objectives of the Curricula

1. To train graduates to be critical and creative thinkers so they can serve important roles in an evolving democratic and global society.
2. To create graduates of high intellectual honesty who will stand up for their ideals.
3. To imbue graduates with the crucial intellectual and moral values, that will allow them to renew society from within.
4. To encourage a temperament in the students for creating, maintaining and participating in a truly democratic society.
5. To form trustworthy and open-minded leaders, who respect others, and are willing to sacrifice themselves for the sake of the common good.
6. To prepare graduates to be able to harmonize communities in the emerging pluralized global society.
