A Catholic university is a private university run by the Roman Catholic Church or by Roman Catholic organizations such as religious institutes. Those with closer ties to the Holy See are specifically called pontifical universities.
By definition, Catholic canon law states that "A Catholic school is understood to be one which is under control of the competent ecclesiastical authority or of a public ecclesiastical juridical person, or one which in a written document is acknowledged as Catholic by the ecclesiastical authority" (Can. 803). Although some schools are deemed "Catholic" because of their identity and a great number of students enrolled are Catholics, it is also stipulated in canon law that "no school, even if it is in fact Catholic, may bear the title 'Catholic school' except by the consent of the competent ecclesiastical authority" (Can. 803 §3).
According to the census of the Vatican's Congregation for Catholic Education, the total number of Catholic universities and higher education institutions around the world is 1,358. The Dominican Order is "the first order instituted by the Church with an academic mission", founding studia conventualia in every convent of the order, and studia generalia at the early European universities such as the University of Bologna and the University of Paris. The Catholic religious order with the highest number of universities around the world today is the Society of Jesus with 114.
Like other private schools, Catholic colleges and universities are generally nondenominational, in that they accept anyone regardless of religion or denominational affiliation, race or ethnicity, nationality, or civil status, provided the admission or enrollment requirements and legal documents are submitted, and rules and regulations are obeyed for a fruitful life on campus. However, non-Catholics, whether Christian or not, may or may not participate in otherwise required campus activities, particularly those of a religious nature.
