After 1989 the cooperation between Catholic theological faculties and the secular academies was standarized. The rules of cooperation between seminaries and theological faculties, existing either in ecclesiastical universities or in the state-controlled ones, were also circumscribed. The aim of this collaboration is to gain the academic degrees by the prospective priests. The author of an article recalls the legal rules, that regulate this cooperation and points the chances of it. Thanks to the collaboration, the seminary is raising academic qualifications of employees, and the students are being educated by the university standards. The university gains an unique group of students, whose spiritual and moral formation, may be an example for a modern graduate in theology. Moreover, throughout affiliating seminaries to the theological faculties, the university has chance to benefit of the rich seminary archives and libraries, and to examine the great architectural, musical and painting treasures, concentrated in diocesan cities.
