The main purposes of the Institute are:

* the theological formation of the faithful, laity and religious, through systematic study and scientific examination of Catholic doctrine;

* preparation of pastoral workers for local communities

* preparation for the various activities of the lay apostolate.

The courses of the Institute are carried out with the academic guidance of the School of Theology of the Pontifical University of the Holy Cross.

The Institute has a specific didactic methodology, which offers the traditional forms of on site teaching (lessons, written assignments, oral examinations) in a flexible form, suited to those who for geographical, professional or family reasons are unable to attend an Institute requiring daily attendance.

All didactic activity is carried out at the University.

The Institute fosters frequent dialogue between students and professors: lesson meetings are particularly important moments in this pedagogical relationship and therefore attendance is compulsory.

The dates of the meetings are indicated on the academic calendar.

Furthermore, a professor with the role of tutor is assigned to each student; the tutor's role is to help students resolve any doubts or difficulties regarding their studies, especially of an organizational or methodological nature.
