Pontifical universities are "academic institutes established or approved directly by the Holy See, composed of three main ecclesiastical faculties (Theology, Philosophy and Canon Law) and at least one other faculty. These academic institutes deal specifically with the Christian revelation and related disciplines, and the Church’s mission of spreading the Gospel, as proclaimed in the Apostolic Constitution both" Sapientia christiana". Many of them, on the other hand, have most of their students studying secular topics.
Pontifical universities follow a European system of degrees in the sacred faculties, granting the baccalaureate, the licentiate, and the doctorate. These ecclesiastical degrees are prerequisites to certain offices in the Roman Catholic Church, especially considering that bishop candidates are selected mainly from priests who are doctors of sacred theology (S.T.D.) or canon law (J.C.D.) and that ecclesiastical judges and canon lawyers must have at least the Licentiate of Canon Law (J.C.L.).
Compared to secular or Catholic universities, which are academic institutions for the study and teaching of a broad range of disciplines, ecclesiastical or Pontifical universities are "usually composed of three principal ecclesiastical faculties, theology, philosophy, and canon law, and at least one other faculty. A Pontifical university specifically addresses Christian revelation and disciplines correlative to the evangelical mission of the Church as set out in the apostolic constitution Sapientia christiana".
