Ecclesiastical Faculties consist of academic programs being offered since the university was founded in 1611, which prepare young men for the priesthood and for lay ministry service in the church.

The degree programs for undergraduate studies were first offered, where the Faculties of Sacred Theology and Philosophy were founded.

It is tasked with the formation of the clergy and of the faithful at the level required for the certification of academic degrees conferred under the authority of the Holy See.

[2] The Faculty of Sacred Theology is as old as the university itself, since the primary purpose of the Dominican Fathers in founding this institution of learning was to train from among the young men who flocked to their lecture rooms worthy ministers of the altar.

And, in seeking the accreditation of the program by the Commission on Higher Education in 1995, the university responded to the needs for well-trained teachers of religion and values.

[5] The Faculty of Canon Law aims to study and to promote the juridical disciplines in the light of the Gospel and to mold the students in the spirit of the Church's common Law, so that they may be prepared for scientific research regarding its development and interpretation, to teach the same in seminaries, houses of studies and Ecclesiastical Faculties, and be trained for professional practice in diocesan and religious curias as well as to hold special ecclesiastical posts.
